    ABSTRACT: To determine if the histology of a breast malignancy influences the appearance of untreated osseous metastases on FDG PET/CT. This retrospective study was performed under IRB waiver. Our Hospital Information System was screened for breast cancer patients who presented with osseous metastases, who underwent FDG PET/CT prior to systemic therapy or radiotherapy from 2009 to 2012. Patients with invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), or mixed ductal/lobular (MDL) histology were included. Patients with a history of other malignancies were excluded. PET/CT was evaluated, blinded to histology, to classify osseous metastases on a per-patient basis as sclerotic, lytic, mixed lytic/sclerotic, or occult on CT, and to record SUVmax for osseous metastases on PET. Following screening, 95 patients who met the inclusion criteria (74 IDC, 13 ILC, and 8 MDL) were included. ILC osseous metastases were more commonly sclerotic and demonstrated lower SUVmax than IDC metastases. In all IDC and MDL patients with osseous metastases, at least one was FDG-avid. For ILC, all patients with lytic or mixed osseous metastases demonstrated at least one FDG-avid metastasis; however, in only three of seven patients were sclerotic osseous metastases apparent on FDG PET. The histologic subtype of breast cancer affects the appearance of untreated osseous metastases on FDG PET/CT. In particular, non-FDG-avid sclerotic osseous metastases were more common in patients with ILC than in patients with IDC. Breast cancer histology should be considered when interpreting non-FDG-avid sclerotic osseous lesions on PET/CT, which may be more suspicious for metastases (rather than benign lesions) in patients with ILC.

    ABSTRACT: To investigate and compare the quantitative accuracy of (90)Y imaging across different generation PET/CT scanners, for the purpose of dosimetry after radioembolization with resin microspheres. A strict experimental and imaging protocol was followed by 47 international sites using the NEMA 2007/IEC 2008 PET body phantom with an 8-to-1 sphere-to-background ratio of (90)Y solution. The phantom was imaged over a 7-day period (activity ranging from 0.5 to 3.0 GBq) and all reconstructed data were analysed at a core laboratory for consistent processing. Quantitative accuracy was assessed through measures of total phantom activity, activity concentration in background and hot spheres, misplaced counts in a nonradioactive insert, and background variability. Of the 69 scanners assessed, 37 had both time-of-flight (ToF) and resolution recovery (RR) capability. These current generation scanners from GE, Philips and Siemens could reconstruct background concentration measures to within 10 % of true values over the evaluated range, with greater deviations on the Philips systems at low count rates, and demonstrated typical partial volume effects on hot sphere recovery, which dominated spheres of diameter <20 mm. For spheres >20 mm in diameter, activity concentrations were consistently underestimated by about 20 %. Non-ToF scanners from GE Healthcare and Siemens were capable of producing accurate measures, but with inferior quantitative recovery compared with ToF systems. Current generation ToF scanners can consistently reconstruct (90)Y activity concentrations, but they underestimate activity concentrations in small structures (≤37 mm diameter) within a warm background due to partial volume effects and constraints of the reconstruction algorithm. At the highest count rates investigated, measures of background concentration (about 300 kBq/ml) could be estimated on average to within 1 %, 5 % and 2 % for GE Healthcare (all-pass filter, RR + ToF), Philips (4i8s ToF) and Siemens (2i21s all-pass filter, RR + ToF) ToF systems, respectively. Over the range of activities investigated, comparable performance between GE Healthcare and Siemens ToF systems suggests suitability for quantitative analysis in a scenario analogous to that of postradioembolization imaging for treatment of liver cancer.

    ABSTRACT: In recent decades, the use of radiopharmaceuticals in the assessment of hepatocellular carcinoma (HCC) has become established, and new findings indicate that radiolabelled choline has considerable potential in this setting. Therefore, in this study we aimed to assess the diagnostic role of (11)C-choline positron emission tomography (PET)/CT, compared with conventional imaging with CT/MRI, in patients with HCC. The study population comprised 45 patients (male to female ratio = 37:8, median age 70.5 years) referred to our institution owing to HCC: 27 at initial diagnosis and 18 for restaging after recurrence. In all cases we performed whole-body (11)C-choline PET/CT and compared its findings with contrast-enhanced CT (n = 35) or MRI (n = 29) or both (n = 15) for a total of 50 paired scans. The reference standard was either histological proof (21 patients) or a multidisciplinary consensus. Diagnostic accuracy was then determined in a scan-based (SBA) and a lesion-based analysis (LBA). On SBA the sensitivity and specificity for PET were 88 and 90 %, respectively, whereas for CT/MRI they were 90 and 73 %, respectively (p > 0.05). On LBA the overall sensitivity and specificity were 78 and 86 %, respectively, for PET vs 65 and 55 % for CT/MRI. Overall we investigated 168 disease sites, of which 100 were in the liver and 68 were extrahepatic. When considering only liver lesions, (11)C-choline PET and CT/MRI showed an accuracy of 66 and 85 %, respectively, while for extrahepatic lesions PET showed an accuracy of 99 %, while the accuracy of CT/MRI was 32 %. In both cases, there was a statistically significant difference in accuracy between the two modalities (p < 0.01). Combination of the PET results with those of CT/MRI resulted in the highest diagnostic accuracy in both analyses, at 92 % for SBA and 96 % for LBA. In 11 patients (24 %) the PET findings modified the therapeutic strategy, the modification proving appropriate in 10 of them. (11)C-Choline PET showed good accuracy in investigating patients with HCC and prompted a change in treatment planning in almost one fourth of patients. The main strength of (11)C-choline PET/CT resides in its ability to detect extrahepatic HCC localizations, but the combination with conventional imaging modalities allowed for the highest diagnostic accuracy.

    ABSTRACT: Despite good to excellent inter-reader agreement in the evaluation of amyloid load on PET scans in subjects with Alzheimer's disease, some equivocal findings have been reported in the literature. We aimed to describe the clinical characteristics of subjects with equivocal PET images. Nondemented subjects aged 70 years or more were enrolled from the MAPT trial. Cognitive and functional assessments were conducted at baseline, at 6 months, and annually for 3 years. During the follow-up period, 271 subjects had (18)F-AV45 PET scans. Images were visually assessed by three observers and classified as positive, negative or equivocal (if one observer disagreed). After debate, equivocal images were reclassified as positive (EP+) or negative (EP-). Scans were also classified by semiautomated quantitative analysis using mean amyloid uptake of cortical regions. We evaluated agreement among the observers, and between visual and quantitative assessments using kappa coefficients, and compared the clinical characteristics of the subjects according to their PET results. In 158 subjects (58.30 %) the PET scan was negative for amyloid, in 77 (28.41 %) the scan was positive and in 36 (13.28 %) the scan was equivocal. Agreement among the three observers was excellent (kappa 0.80). Subjects with equivocal images were more frequently men (58 % vs. 37 %) and exhibited intermediate scores on cognitive and functional scales between those of subjects with positive and negative scans. Amyloid load differed between the EP- and negative groups and between the EP+ and positive groups after reclassification. Equivocal amyloid PET images could represent a neuroimaging entity with intermediate amyloid load but without a specific neuropsychological pattern. Clinical follow-up to assess cognitive evolution in subjects with equivocal scans is needed.

    ABSTRACT: The objective of this study was to determine the incremental staging information provided by positron emission tomography/computed tomography (PET/CT) and its impact on management plans in patients with untreated stage III-IV head and neck squamous cell carcinoma (HNSCC). We prospectively studied, between September 2011 and February 2013, 84 consecutive patients [median age 63.5 years (39-84); 73 men] with histologically confirmed HNSCC. First, based on a conventional work-up (physical examination, CT imaging of the head, neck and chest), the multidisciplinary Head and Neck Tumour Board documented the TNM stage and a management plan for each patient, outlining the modalities to be used, including surgery, radiation therapy (RT), chemotherapy or a combination. After release of the PET/CT results, new TNM staging and management plans were agreed on by the multidisciplinary Tumour Board. Any changes in stage or intended management due to the PET/CT findings were then analysed. The impact on patient management was classified as: low (treatment modality, delivery and intent unchanged), moderate (change within the same treatment modality: type of surgery, radiation technique/dose) or high (change in treatment intent and/or treatment modality → curative to palliative, or surgery to chemoradiation or detection of unknown primary tumour or a synchronous second primary tumour). TNM stage was validated by histopathological analysis, additional imaging or follow-up. Accuracy of the conventional and PET/CT-based staging was compared using McNemar's test. Conventional and PET/CT stages were discordant in 32/84 (38 %) cases: the T stage in 2/32 (6.2 %), the N stage in 21/32 (65.7 %) and the M stage 9/32 (28.1 %). Patient management was altered in 22/84 (26 %) patients, with a moderate impact in 8 (9.5 %) patients and high impact in 14 (16.6 %) patients. PET/CT TNM classification was significantly more accurate (92.5 vs 73.7 %) than conventional staging with a p value < 0.001 (McNemar's test). PET/CT should be implemented in the routine imaging work-up of stage III-IV HNSCC.

    ABSTRACT: Monitoring of response to neoadjuvant chemotherapy (NCT) is important for optimal management of patients with breast cancer. (99m)Tc-3PRGD2 SPECT is a newly developed imaging modality for evaluating tumor vascular status. In this study, we investigated the application of (99m)Tc-3PRGD2 SPECT in evaluating therapy response to NCT in patients with stage II or III breast cancer. Thirty-three patients were scheduled to undergo (99m)Tc-3PRGD2 SPECT at baseline, after the first and second cycle of NCT. Four patients had extremely low (99m)Tc-3PRGD2 uptake at baseline, and were not included in the subsequent studies. Changes in tumor to nontumor (T/N) ratio were compared with pathological tumor responses classified using the residual cancer burden system. Receiver operator characteristic analysis was used to compare the power to identify responders between the end of the first and the end of the second cycle of NCT. The impact of breast cancer subtype on (99m)Tc-3PRGD2 uptake was evaluated. The correlation between (99m)Tc-3PRGD2 uptake and pathological tumor response was also evaluated in each breast cancer subtype. Surgery was performed after four cycles of NCT and pathological analysis revealed 18 responders and 15 nonresponders. In patients with clearly visible (99m)Tc-3PRGD2 uptake at baseline, the sensitivity, specificity, and negative predictive value of (99m)Tc-3PRGD2 SPECT were 86.7 %, 85.7 % and 86.7 % after the first cycle of NCT, and 92.9 %, 93.3 % and 93.3 % after the second cycle, respectively. Among these patients, the HER-2-positive group demonstrated both higher T/N ratios and a greater change in T/N ratio than patients with other breast cancer subtypes (P < 0.05). A strong correlation was found between changes in T/N ratio and pathological tumor response in the HER-2-positive group (P < 0.03). (99m)Tc-3PRGD2 SPECT seems to be useful for determining the pathological tumor response in patients with stage II or III breast cancer undergoing NCT, especially those with the HER-2-positive subtype.

    ABSTRACT: Myocardial contractile function is under the control of cardiac sympathetic activity. Three-dimensional speckle tracking echocardiography (3D-STE) and cardiac imaging with (123)I-metaiodobenzylguanidine ((123)I-MIBG) are two sophisticated techniques for the assessment of left ventricular (LV) deformation and sympathetic innervation, respectively, which offer important prognostic information in patients with heart failure (HF). The purpose of this investigation was to explore, in patients with systolic HF, the relationship between LV deformation assessed by 3D-STE and cardiac sympathetic derangement evaluated by (123)I-MIBG imaging. We prospectively studied 75 patients with systolic HF. All patients underwent a 3D-STE study (longitudinal, circumferential, area and radial) and (123)I-MIBG planar and SPECT cardiac imaging. 3D-STE longitudinal, circumferential and area strain values were correlated with (123)I-MIBG late heart to mediastinum (H/M) ratio and late SPECT total defect score. After stratification of the patients according to ischaemic or nonischaemic HF aetiology, we observed a good correlation of all 3D-STE measurements with late H/M ratio and SPECT data in the ischaemic group, but in patients with HF of nonischaemic aetiology, no correlation was found between LV deformation and cardiac sympathetic activity. At the regional level, the strongest correlation between LV deformation and adrenergic innervation was found for the left anterior descending coronary artery distribution territory for all four 3D-STE values. In multivariate linear regression analyses, including age, gender, LV ejection fraction, NYHA class, body mass index, heart rate and HF aetiology, only 3D-STE area and radial strain values significantly predicted cardiac sympathetic derangement on (123)I-MIBG late SPECT. This study indicated that 3D-STE measurements are correlated with (123)I-MIBG planar and SPECT data. Furthermore, 3D-STE area and radial strain values, but not LVEF, predict cardiac sympathetic derangement in human postischaemic HF.

    ABSTRACT: To determine whether (18)F-FDG uptake in breast cancer correlates with immunohistochemically defined subtype and is able to predict molecular subtypes. This retrospective study involved 306 patients with 308 mass-type invasive breast cancers (mean size 2.65 cm, range 1.0-15.0 cm) who underwent (18)F-FDG PET/CT before therapy. The correlations between primary tumour (18)F-FDG uptake on PET/CT, expressed as SUVmax, and clinicopathological findings and molecular subtype, i.e. luminal A, luminal B (HER2-negative), luminal B (HER2-positive), HER2-positive and triple-negative, were analysed. The predictors of these subtypes were investigated. The mean SUVmax of the 308 tumours was 5.33 ± 3.63 (range 1.15-19.01). Among the subtypes of the 308 tumours, 87 (28.2 %) were luminal A, 111 (36.0 %) were luminal B (HER2-negative), 31 (10.1 %) were luminal B (HER2-positive), 26 (8.4 %) were HER2-positive and 53 (17.2 %) were triple-negative, and the corresponding mean SUVmax were 3.41 ± 2.07 (range 1.18-14.30), 5.17 ± 3.52 (range 1.35-19.01), 6.57 ± 3.84 (range 1.42-15.58), 7.55 ± 3.63 (range 2.30-13.60) and 6.97 ± 4.17 (range 1.15-16.06), respectively. A cut-off value of 3.60 yielded 70.1 % sensitivity and 66.1 % specificity with an area under the receiver operating characteristics curve (AUC) of 0.734 for predicting that a tumour was of the luminal A subtype. A cut-off value of 6.75 yielded 65.4 % sensitivity and 75.2 % specificity with an AUC of 0.704 for predicting a HER2-positive subtype. SUVmax, a metabolic semiquantitative parameter, shows a significant correlation with the molecular subtype of breast cancer, and is useful for predicting the luminal A or HER2-positive subtype.

    ABSTRACT: The prostate-specific membrane antigen (PSMA) has recently emerged as a target for radionuclide imaging and therapy of prostate cancer [1, 2]. However, PSMA expression was also shown on the cell membrane of endothelial cells of tumour neovasculature in a number of other cancers such as renal cell carcinoma [3, 4], colon carcinoma, neuroendocrine tumours, melanoma or breast cancer [3]. However, to our knowledge no study has yet investigated the expression of PSMA in the neovasculature of differentiated thyroid cancer (DTC).[68Ga]PSMA-HBED-CC can be used for positron emission tomography (PET)/CT-based staging of prostate cancer [1] as well as for eligibility screening for and monitoring of PSMA-targeted radionuclide therapy [2].Considering the limited number of therapeutic options currently available for patients with metastasized, 131I-negative, [18F]-2-fluorodeoxyglucose-positive DTC [5], we hypothesized that PSMA expression could be present in DTC as well. This would provide an intere ...

    ABSTRACT: The purpose of the study was to assess the prevalence of pulmonary embolism (PE) and other lung diseases among pregnant women with suspected PE and to calculate the radiation exposure to patient and fetus in this population. As a secondary aim, we evaluated the negative predictive value of a normal ventilation/perfusion single photon emission computed tomography (V/P SPECT) examination in pregnancy. We studied all 127 pregnant women who had suspected PE and had undergone V/P SPECT at our institution in the course of a 5-year period. Radiation exposure to patient and fetus and the negative predictive value of a normal V/P SPECT examination were also measured. V/P SPECT identified PE in 11 women (9 %). Moreover, in 15 women (12 %) the examination revealed pneumonia (in 2 cases in addition to PE) and in 1 woman signs of airway obstruction were revealed. Among the 116/127 women (91 %) where PE was ruled out by V/P SPECT, none was diagnosed subsequently with PE or deep venous thrombosis (DVT) during the same pregnancy or puerperal period. For P SPECT, the calculated fetal absorbed dose was < 0.6 mGy,and the calculated breast absorbed dose 0.6 mGy. For V SPECT, the calculated fetal absorbed dose was < 0.014 mGy and the breast absorbed dose 0.25 mGy. The prevalence of PE was low (9 %) among pregnant women with suspected disease. Pneumonia was diagnosed in 12 % of patients. The negative predictive value of V/P SPECT was high, and the radiation exposure from V/P SPECT was low both for fetus and patient.

    ABSTRACT: Purpose Fusion dual-tracer SPECT imaging enables physiological rather than morphological voxel-based partitioning and dosimetry for 90Y hepatic radioembolization (RE). We evaluated its prognostic value in a large heterogeneous cohort of patients with extensive hepatic malignancy. Methods A total of 122 patients with primary or secondary liver malignancy (18 different cell types) underwent SPECT imaging after intraarterial injection of 99mTc macroaggregated albumin (TcMAA) as a simulation of subsequent 90Y microsphere distribution, followed by administration of an excess of intravenous 99mTc-labelled sulphur colloid (TcSC) as a biomarker for functional liver, and a second SPECT scan. TcMAA distribution was used to estimate 90Y radiation absorbed dose in tumour (D T) and in functional liver. Laboratory and clinical follow-up were recorded for 12 weeks after RE, and radiographic responses according to (m)RECIST were evaluated at 3 and 6 months. Dose-response relationships were determined for efficacy and toxicity. Results Patients were treated with a median of 1.73 GBq activity of resin microspheres (98 patients) or glass microspheres (24 patients), in a whole-liver approach (97 patients) or a lobar approach (25 patients). The objective response rate was 41 % at 3 months and 48 % at 6 months. Response was correlated with D T (P P D T was independently associated with survival (P P P Conclusion Fusion dual-tracer SPECT imaging offers a physiology-based functional imaging tool to predict efficacy and toxicity of RE. This technique can be refined to define dosing thresholds for specific tumour types and treatments, but appears generally predictive even in a heterogeneous cohort.

    ABSTRACT: A 46-year-old woman with an history of colon cancer treated with left hemicolectomy, chemotherapy, radiotherapy and pulmonary nodule resections was referred for a series of fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT to assess the disease status.The last FDG PET/CT revealed a focal uptake to an endotracheal lesion almost completely obstructing the lumen (arrows); PET scan, endotracheal FDG uptake, maximum intensity projection (a), PET sagittal view (b), CT sagittal view (c), axial view (d).The patient underwent bronchoscopy which restored the patency of the tracheal lumen. Morphological assessment and immunohistochemistry identified the excised specimen as metastatic adenocarcinoma of the large intestine (CDX2-ck20 positive, ck7-TTF1 negative).From 20 to 50 % of primary extrapulmonary solid malignancies show pulmonary metastases during their biological course [1]. Endotracheal/endobronchial metastases from non-lung cancer are rare and might be mainly associated with ...

    ABSTRACT: The aim of this study was to determine the prevalence of salivary and lacrimal gland dysfunction and a second primary malignancy in patients from Taiwan with thyroid cancer after radioiodine therapy. This nationwide population-based cohort study was based on data obtained from the Taiwan National Health Insurance Database from 2000 to 2011. A total of 1,834 thyroid cancer patients treated with (131)I therapy and 1,834 controls (thyroid cancer without (131)I therapy) selected by 1:1 matching on a propensity score were enrolled. The cumulative (131)I dose in each patient was calculated. A Cox proportional hazards model was applied to estimate the effect of radiation from the (131)I therapy on the risk of salivary and lacrimal gland impairment as well as second primary malignancies in terms of hazard ratios (HRs) and 95 % confidence intervals (CIs). In patients treated with (131)I therapy and in controls, the incidence rates of salivary gland dysfunction were 6.76 and 1.01 per 10,000 person-years, respectively (HR 6.81, 95 % CI 0.74 - 55.3), the incidence rates of keratoconjunctivitis sicca (KCS) were 13.6 and 16.3 per 10,000 person-years, respectively (HR 0.84, 95 % CI 0.41 - 1.73), and the incidence rates of second primary malignancy were 76.7 and 62.4 per 10,000 person-years, respectively (HR 1.23, 95 % CI 0.88 - 1.72). The risk of salivary secretion impairment significantly increased with increasing administered doses (HR 14.3, 95 % CI 1.73 - 119.0). However, there was no increase in the incidence of KCS or secondary cancer in patients treated with higher doses. (131)I therapy insignificantly increased the risk of salivary gland dysfunction and second primary malignancy. In patients with higher cumulative doses, an increase in the incidence of salivary gland dysfunction was observed. By contrast, we did not find an association between (131)I treatment and KCS development.
