    ABSTRACT: This paper describes the external audit measurements conducted in 2 UK centres implementing Total Skin Electron Beam Therapy (TSEBT) and the results obtained. Measurements of output, energy, beam flatness and symmetry at standard distance (95cmSSD or 100cmSSD) were performed using a parallel plate chamber in solid water. Similarly, output and energy measurements were also performed at the treatment plane for single and dual fields. Clinical simulations were carried out using thermoluminescent dosemeters (TLD) and Gafchromic film on an anthropomorphic phantom. Extended distance measurements confirmed local values for the beam dosimetry at centres A and B were within 2% for outputs and 1mm agreement of the expected R50,D value. Clinical simulation using TLD showed an agreement of -1.6% and -6.7% compared to the expected mean trunk dose for each centre respectively and a variation within 10% (±1SD) across the trunk. The film results confirmed that the delivery of the treatment technique at each audited centre complies with EORTC recommendations. This audit methodology has proven to be a successful way to confirm the agreement of dosimetric parameters for TSEBT treatments at both audited centres and could serve as the basis for an audit template to be used by other audit groups. Advances In Knowledge: TSEBT audits are not established in the UK due to a limited number of centres carrying out the treatment technique. This paper describes the audits performed at two UK centres prior to their clinical implementation.

    ABSTRACT: This paper presents an overview of the recent developments and requirements in radiotherapy dosimetry, with a particular emphasis on the development of optical fibre dosimeters for radiotherapy applications, focusing particularly on in-vivo applications. Optical fibres offer considerable advantages over conventional techniques for radiotherapy dosimetry, due to their small size, immunity to electromagnetic interferences and their suitability for remote monitoring and multiplexing. The small dimensions of optical fibre based dosimeters, together with being lightweight and flexible, mean that they are minimally invasive and thus particularly suited to in-vivo dosimetry. This means that the sensor can be placed directly inside a patient, e.g. for brachytherapy treatments, the optical fibres could be placed in the tumour itself, or into nearby critical tissues requiring monitoring, via the same applicators or needles used for the treatment delivery thereby providing real-time dosimetric information. The paper outlines the principal sensor design systems along with some of the main strengths and weaknesses associated with the development of these techniques. The successful demonstration of these sensors in a range of different clinical environments is also presented.

    ABSTRACT: In 2011, the ICRP recommended a substantial reduction in the equivalent dose limit for the lens of the eye, in line with a reduced threshold of absorbed dose for radiation-induced cataracts. This is of particular relevance in Interventional Radiology (IR) where it is well established that staff doses can be significant, however there is a lack of data on IR eye doses in terms of Hp(3). Hp(3) is the personal dose equivalent at a depth of 3mm in soft tissue and is used for measuring lens dose. We aimed to obtain a reliable estimate of eye dose to IR operators. Lens doses were measured for four interventional radiologists over a 3-month period using dosimeters specifically designed to measure Hp(3). Based on their typical workloads, two of the four interventional radiologists would exceed the new ICRP dose limit with annual estimated doses of 31mSv and 45mSv to their left eye. These results are for an "unprotected" eye and for IR staff who routinely wear lead glasses, the dose beneath the glasses is likely to be significantly lower. Staff eye dose normalised to patient Kerma-Area Product (KAP) and eye dose per procedure has been included in the analysis. Eye doses to IR operators have been established using a dedicated Hp(3) dosimeter. Estimated annual doses have the potential to exceed the new ICRP limit. Advances in knowledge: We have estimated lens dose to interventional radiologists in terms of Hp(3) for the first time in an Irish hospital setting.

    ABSTRACT: Visuospatial ability is fundamental to the cognitive understanding of the three-dimensional environment, and is widely recognised as an important skill in the performance of challenging visuospatial tasks. Its contribution to attainment and performance in a variety of professional disciplines is recognised, but there is relatively little known in relation to its relevance in radiological practice. On the basis of a review of the existing cognitive psychological literature and on the basis of the author's own observations, and on the assumption that spatial ability is of increasing and fundamental importance to high-level performance as a radiologist, it is proposed that consideration should be given to the testing of visuospatial ability as part of the selection process for prospective applicants to radiology training programmes.

    ABSTRACT: In the last decade, electronic brachytherapy (EB) has emerged as an attractive modality for the treatment of skin lesions and intraoperative partial breast irradiation, as well as finding wider applications in intracavitary and interstitial sites. These miniature x-ray sources, which operate at low kilovoltage energies (<100kV), have reduced shielding requirements and inherent portability, so can be used outside the traditional realms of the radiotherapy department. However, steep dose gradients and increased sensitivity to inhomogeneities challenge accurate dosimetry. Secondly, ease of use does not mitigate the need for close involvement by Medical Physics Experts and consultant oncologists. Finally, further studies are needed to relate the more heterogeneous dose distributions to clinical outcomes. With these provisos, the practical convenience of EB strongly suggests that it will become an established option for selected patients, not only in radiotherapy departments but also in a range of operating theatres and clinics around the world.

    ABSTRACT: Objectives: Diffusion-weighted imaging (DWI) is an important technique for the localisation of prostate cancer and its response assessment during treatment with radiotherapy. However, it has known limitations in terms of distortions and artefacts using standard acquisition techniques. This study evaluates two alternative methods which offer the promise of improved image quality and the potential for more reliable and consistent diffusion data. Methods: Three DWI techniques were investigated; single-shot EPI, EPI combined with reduced volume excitation (ZoomIT) and read-out segmentation with navigator-echo correction (RESOLVE). Daily measurements of ADC value were made in a quality assurance phantom to assess the repeatability of each sequence. In order to evaluate the geometric integrity of these sequences, ten normal volunteers were scanned and the prostate was contoured to compare its similarity with T2-weighted images. Results: Phantom ADC values were significantly higher using the standard EPI sequence compared to the other two sequences. Differences were also observed between sequences in terms of repeatability with RESOLVE and EPI performing better than ZoomIT. Overall the RESOLVE sequence provided the best agreement for the in vivo data with smaller differences in volume and higher contour similarity compared to T2-w imaging. Conclusions: Important differences have been observed between each of the three techniques investigated with RESOLVE performing the best overall. We have adopted this sequence for routine radiotherapy simulation of prostate patients at our Centre. Advances in Knowledge: This work will be of interest to the increasing number of Centres wanting to incorporate quantitative DWI in a clinical setting.

    ABSTRACT: Objectives: This study investigated the effectiveness of stereotactic body radiotherapy with helical tomotherapy (T-SBRT) for treating medically inoperable primary and second-primary (SPLN) early stage non-small cell lung neoplasm and evaluated whether the movement of organising pneumonia (OP) within the irradiation field (IF) can be detected via analysis of radiological changes. Methods: Patients (n = 16) treated for 1 year (2011-2012) at our hospital by T-SBRT at a total dose of 60 Gy in five fractions were examined retrospectively. Outcome and toxicity were recorded, and were separately described for SPLN. Computed tomography scans were reviewed by a single radiologist. Results: Of 16 the patients, five (31.3%) had primary lung malignancies, 10 (62.5%) had SPLN, and one case (6.2%) had isolated mediastinal metastasis of lung neoplasm. Pathological evidence was obtained for 72.2% of all lesions. The median radiological follow-up was 11.0 months (10.5 for SPLN). For all cases, the 6- and 12-month survival rates were 100% and 77.7% (100% and 71.4%, respectively, for SPLN), and the 6- and 12-month loco-regional control rates were 100% in all cases. Two (12.5%) of 16 patients developed grade 3 late transient radiation pneumonitis following steroid therapy and one (6.2%) presented asymptomatic infiltrates comparable to OP opacities. Conclusions: T-SBRT seems to be safe and effective. Advances in knowledge: Mild OP is likely associated with radiation-induced anomalies in the IF, identification of migrating opacities can help discern relapse of radiation-induced opacities.

    ABSTRACT: Current cancer therapy strategy is mostly population-based, however, there are large differences in tumor response among patients. It is therefore important for the treating physicians to know individual tumor response. In recent years, many studies proposed the use of computerized PET/CT image analysis in the evaluation of tumor response. Results showed that the computerized analysis overcome some major limitations of current qualitative and semi-quantitative analysis and led to improved accuracy. In this review, we summarize these studies in the four steps of the analysis: image registration, tumor segmentation, image feature extraction, and response evaluation. Future works are proposed and challenges described.

    ABSTRACT: Central nervous system (CNS) stimulation is becoming increasingly prevalent. Deep brain stimulation (DBS) has been proven to be an invaluable treatment for movement disorders and is also useful in many other neurological conditions refractory to medical treatment such as chronic pain and epilepsy. Neuroimaging plays an important role in operative planning, target localisation and in post-operative follow up. The use of imaging in determining the underlying mechanisms of DBS is increasing, and the dependence on imaging is likely to expand as deep brain targeting becomes more refined. This article will address the expanding role of radiology and highlight issues, including MRI safety concerns, that radiologists may encounter when confronted with a patient with CNS stimulation equipment in situ.

    ABSTRACT: Objectives: To analyze imaging features of subtypes of Castleman Disease (CD), emphasizing differentiating features from lymphoma. Methods: IRB-approved, HIPAA compliant, retrospective study examined 30 patients with CD. 30 patients (20 women, mean age: 46 years, range 22-87) with histopathologically confirmed CD and pre-treatment imaging formed the analytic cohort. Imaging at presentation in all patients (30 CT, 5 PET/CT, 4 MR, 3 US) and subsequent imaging in three cases that developed lymphoma was reviewed by two radiologists in consensus. Results: Subtypes: hyaline-vascular(n=18); multicentric not otherwise specified (NOS)(n=6); HHV-8 associated( n=2); mixed unicentric(n=2); pure plasma-cell variant(n=1); unicentric NOS(n=1). Distribution: unicentric(n=17); multicentric(n=13). Nodal sites: unicentric: 13thoracic, 3abdominal and 1 cervical; multicentric: 9abdominal, 8thoracic, 6cervical, 5inguinal, 4axillary and 4supraclavicular. On CT, differentiating features from lymphoma were calcification(n=8; 26.7%) and heterogeneous enhancement(n=5; 19.2%). No association between CD subtype, degree or enhancement pattern, or calcification was noted. On PET/CT(n=5), nodes were typically FDG-avid(n=4). On ultrasound(n=3), nodes were hypoechoic, homogeneous with posterior acoustic enhancement. On MR(n=4), nodes were hypointense(n=2) to isointense(n=2) on T1-weighted images and isointense(n=1) to hyperintense(n=3) on T2-weighted images. All(n=4) demonstrated homogeneous enhancement. Three cases developed non-Hodgkin's lymphoma, 2 of the 3 had larger spleens, and these cases had effusions/ascites. Conclusions: CD can be unicentric or multicentric, and involve nodes above and below the diaphragm. Patients with CD can develop lymphoma. Advances in knowledge: Assessing individual risk of developing lymphoma in patients with CD is difficult, though the findings of splenomegaly, pleural effusion and ascites may be suggestive.

    ABSTRACT: Objectives: Intravenous pulse methylprednisolone therapy (IPMT) is an important treatment option for postinfectious obliterative bronchiolitis (OB), although it must be used carefully and only in selected patients because of its drawbacks. This study evaluated whether computed tomography (CT) and clinical features of children with postinfectious OB can predict their responsiveness to IPMT. Methods: We searched the medical records for patients (< 18 years) who were diagnosed with postinfectious OB between January 2000 and December 2011. Seventeen children who received IPMT were included in this study. All underwent chest CT before and after IPMT. The radiologic features seen on pretreatment CT were recorded. The air-trapping area percentages on pre- and post-treatment CT images were determined. The nine patients who exhibited decreased air-trapping on post-treatment CT scans relative to pretreatment scans, were classed as responders. The patient ages and time from the initial pneumonia to IPMT were recorded. Results: All responders, but only four non-responders, had thickened bronchial walls before treatment (p = 0.029). The two groups did not differ significantly in terms of bronchiolitis, bronchiectasis or the air-trapping extent, although the responders had a significantly shorter median interval between the initial pneumonia and IPMT (4 vs. 50 months, p = 0.005) and were significantly younger (median, 2 vs. 7.5 years, p = 0.048). Conclusions: Immediate IPMT may improve the degree of air-trapping in children with postinfectious OB if they show a thickened bronchial wall on CT. Advances in knowledge: Children with postinfectious OB may respond favorably to IPMT when pretreatment CT indicates bronchial-wall thickening.

    ABSTRACT: Objectives: To evaluate the role of an ultra-low-dose dual-source computed tomography coronary angiography (CTCA) scan with high pitch for delimiting the range of the subsequent standard CTCA scan. Methods: Thirty patients with an indication for CTCA were prospectively examined using a two-scan dual-source CTCA protocol (2 x 64 x 0.6 mm; pitch 3.4; rotation time of 280 msec; 100 kV): Scan 1 acquired with one fifth of the tube current suggested by the automatic exposure control software (CareDose 4D, using 100 kV and 370 mAs as a reference) with the scan length from the tracheal bifurcation to the diaphragmatic border. Scan 2 was acquired with standard tube current extending with reduced scan length based on Scan 1. Nine central coronary artery segments were analyzed qualitatively on both scans. Results: Scan 2 (105.1±10.1mm) was significantly shorter than Scan 1 (127.0±8.7mm). Image quality scores were significantly better for Scan 2. However, in 5 of 6 patients (83%) with stenotic coronary artery disease, a stenosis was already detected in Scan 1 and in 13 of 24 patients (54%) with non-stenotic coronary arteries, a stenosis was already excluded by Scan 1. Using Scan 2 as reference, the positive and negative predictive value of Scan 1 was 83% (5 of 6 patients) and 100% (13 of 13 patients), respectively. Conclusions: An ultra-low-dose CTCA planning scan enables a reliable scan length reduction of the following standard CTCA scan and allows for correct diagnosis in a substantial proportion of patients. Advances in knowledge: Further dose reductions are possible due to a change in the individual patient's imaging strategy as a prior ultra-low-dose CTCA scan may already rule out the presence of a stenosis or may lead to a direct transferal to an invasive catheter procedure.

    ABSTRACT: Objectives: We report our experience in providing palliative radiation (RT) to patients with head and neck cancers (HNC). Our hypofractionated regimen, "0-7-21", treats patients with 24 Gy in 3 fractions. Methods: Patients, disease and response data were retrieved for candidates of "0-7-21" from 2005-2012. Primary endpoints included symptom and tumour size responses to RT based on RECIST guidelines. Secondary endpoints included progression-free survival within the irradiated field (PFS), overall survival (OS) and symptomatic progression-free survival (SPFS), calculated using Kaplan-Meier method and adverse events. Cox proportional hazards regression and logistic regression were used to investigate for prognostic factors. Results: A total of 110 patients were included. Among the patients, 40% and 31% had complete response for symptoms and tumour size respectively, 42% and 50% had partial response for symptoms and tumour size respectively, and 15% had stability of symptom and tumour size. Median 6-months OS was 51% and PFS within the irradiated field was 39%. Planning target volume was predictive of OS (p<0.001), PFS (p<0.001) and SPFS (p<0005) while higher TNM stage was associated with poorer tumour response (p=0.02). Conclusion: "0-7-21" is an effective and well-tolerated palliative RT regimen for patients with HNC. There was excellent symptom and local control with acceptable toxicity profile in these patients. Advances in knowledge: This is the first study to describe the outcomes of 0-7-21 in treating advanced head and neck cancers. The positive results suggest that 0-7-21 provides excellent palliation with minimal toxicity, with significantly less on-treatment time than current published palliative RT regimen.

    ABSTRACT: Objective: To evaluate the feasibility of measuring the stiffness of corpus cavernosum penis (CCP) with shear-wave elastography (SWE). Methods: 40 healthy volunteers with ages ranging from 19 to 81 years (mean 36, SD 17 years) were selected in this study. The ultrafast ultrasound device-Aixplorer (SuperSonic Imagine, Aix en Provance, France) was used for the research and the probe selected was SuperLinear SL15-4. The shear wave stiffness (SWS) of corpus cavernosum penis (CCP) was measured using SWE images. The measurement indexes of SWS included: ➀ SWS of CCP measured in the transverse section (SWS-T), ➁ SWS of CCP measured in the longitudinal section (SWS-L), ➂ mean of SWS-T and SWS-L (SWS-M). The interval of hormone test and SWE examination of each subject was less than 7 days. Paired t-test was used to analyze the differences between SWS-T and SWS-L. The Pearson correlation was used to analyze the correlation of SWS of CCP with age as well as sex hormone levels. Results: There was no significant difference between SWS-T and SWS-L (P>0.05). SWS (SWS-T, SWS-L, SWS-M) was negatively correlated with age and estradiol value, and SWS (SWS-T, SWS-L, SWS-M) was positively correlated with testosterone value. Conclusion: SWE could serve as a new noninvasive method of evaluating the stiffness of CCP. Advances in knowledge: It is the first time that we have discussed the feasibility of measuring the stiffness of CCP with SWE and analyzed the correlation of SWS of CCP with age as well as sex hormone levels.

    ABSTRACT: Objectives: To simultaneously improve patient care processes and clinical research activities by starting a hypothesis-driven reorganisation trajectory mimicking the rigorous methodology of a prospective clinical trial. Methods: The design of this reorganisation trajectory was based on the model of a prospective trial. It consisted of 1) listing problems and analysing their potential causes, 2) defining interventions, 3) defining endpoints and 4) measuring the effect of the interventions (i.e. at baseline and after one and two years). The primary endpoint for patient care was the number of organisational root causes of incidents/ near incidents; for clinical research it was the number of patients in trials. There were several secondary endpoints. We analysed the data using two sample z-tests, chi square, a Mann Whitney U test and the one-way ANOVA with Bonferroni correction. Results: The number of organisational root causes was reduced by 27% (p<0.001). There was no effect on the percentage of patients included in trials. Conclusions: The reorganisational trajectory was successful for the primary endpoint of patient care and had no effect on clinical research. Some confounding events hampered our ability to draw strong conclusions. Nevertheless, the transparency of this approach can give medical professionals more confidence in moving forward with other organisational changes in the same way. Advances in knowledge: This paper is novel because managerial interventions were set up similarly to a prospective clinical trial. This study is the first of its kind in radiotherapy and this approach can contribute to discussions about the effectiveness of managerial interventions.

    ABSTRACT: Objectives: A review of SBRT for oligometastases defined as three or fewer sites of isolated metastatic disease. The aim was to identify local control, overall survival (OS) and progression free survival (PFS) of patients receiving SBRT for OM disease. Methods: Data was analysed for SBRT delivered between 1/9/10-31/3/14. End points included local control, progression free survival, overall survival and toxicity. Results: 76 patients received SBRT. Median age was 60 (31-89) years. 44 were male. Median follow-up was 12.3(0.2-36.9) months. Major primary tumour sites included colorectal (38%), breast (18%) and prostate (12%). Treatment sites included lymph nodes (42%), bone and spine (29%) and soft tissue (29%). 42% were previously treated with conventional radiotherapy. 45% were disease free after SBRT. 4% had local relapse, 45% had distant relapse, 6% had local and distant relapse. Local control was 89%. OS was 84.4% at 1 year and 63.2% at 2 years. PFS was 49.1% at 1 year and 26.2% at 2 years. Toxicities included duodenal ulcer and biliary stricture formation. Conclusion: SBRT can achieve durable control of OM lesions and results in minimal radiation-induced morbidity. Advances in knowledge: This cohort is one of the largest reported to date and contributes to the field of SBRT in oligometastases which is emerging as an important research area. It is the only study reported from the UK and uses a uniform technique throughout. The efficacy and low toxicity with durable control of local disease with this approach is shown setting the foundations for future randomised studies.
