    ABSTRACT: Objectives: To determine the comparative diagnostic performance of standard-b-value (>=500mm(2)) versus low-b-value (<500s/mm(2)) DWI for discriminating malignant from benign vertebral compression fractures. Methods: 12 studies with a total of 350 malignant and 312 benign vertebral fractures were included. Results: The ADC value of benign vertebral compression fractures was lower than malignant vertebral compression fractures (SMD= 1.81, 95%CI 0.98 to 2.64 Z=4.27,P<0.05). ADC value difference were more pronounced in the group of low-b-value DWI (SMD= 2.31, 95%CI 1.02 to 3.60 Z=3.51,P<0.05) than group of standard-b-value DWI (SMD= 1.38, 95%CI 0.18 to 2.59 Z=2.25,P<0.05). Ethnicity stratified analysis demonstrated higher ADC values in benign vertebral compression fractures in comparison to malignant tissues in both the Asian and Caucasian subgroups (Asians: SMD=2.400, 95 % CI=1.447∼3.354, P<0.05; Caucasians: SMD=0.592, 95 % CI=-0.848∼2.032, P<0.05, respectively). And the ADC value difference were more pronounced in the group of Asian. Conclusions: ADC value appear to be a reliable method to differentiate benign from malignant fractures. Low-b-value DWI were more valuable parameters than standard-b-value DWI for discriminating malignant from benign vertebral compression fractures. And the diffusion characteristics of the benign vertebral fractures such as the osteoporosis, trauma and infection have rarely been investigated separately. Advances in knowledge: The use of low-b-value DWI for differentiation of benign and malignant vertebral fractures is recommended.

    ABSTRACT: Objective: to study the precise location of fracture line in Hangman's fracture to determine the fracture patterns, symmetry and involvement of different vertebral elements. Methods: Thirty-two cases of hangman's fractures were retrospectively evaluated. All patients presented with motor vehicle accidents. CT scans were studied to accurately localise the fracture lines. Symmetry of fractures lines on both sides was assessed and involvement of the vertebral bodies, lamina, facet joints and foramen transversarium was also determined. Results: Twenty patients showed asymmetric fracture locations, 13 of them had a unilateral pedicle fracture and a contralateral pars fracture which comprised the commonest injury pattern (40% of cases). Less frequent combinations for the two sides of asymmetric C2 ring disruption include pars-vertebral body (3 patients), pedicle-vertebral body (2 patients), and pedicle-lamina (2 patient). Twelve patients showed symmetrical fractures (5 through the pars and 7 through the pedicles). Vertebral body and facet joint involvement were demonstrated in 15 (47%), 16 (50%) cases respectively. Eighteen cases had fractures extending into the foramen transversarium (56%). In total, 26 fracture lines primarily affected the pars (40%) and 31 affected the pedicles (49%). Conclusions: asymmetric Hangman's fracture is more common with the usual pattern being fracture pedicle on one side and pars on the other followed by the symmetric bilateral pedicle and bilateral pars fractures. Fracture lines running into the transverse foramen and facet joints are very frequent as well as those involving the vertebral bodies. Advances in knowledge: Controversy in literature regarding the fracture locations in Hangman's injury due to lack of studies that address this subject. This paper is the first to describe precisely the anatomical locations and patterns of this injury.

    ABSTRACT: Biochemical recurrence after treatment for prostate cancer (PCa) is a significant issue. Early diagnosis of local recurrence is important for making prompt treatment decisions and is strongly associated with patient prognosis. Without salvage therapy, the average time from development of local recurrence to distant metastasis is approximately 3 years. Biochemical recurrence does not differentiate local recurrence from systemic disease; there is no reliable way to clinically diagnose local recurrence. Recent advances in multiparametric MRI (mp-MRI) techniques have markedly improved detection of local recurrence following therapy. However, a wide variety of entities can mimic recurrent PCa at mp-MRI. Therefore, the purpose of this pictorial review is to discuss the MRI findings of locally recurrent PCa and its mimics, emphasizing the key MRI features that help to differentiate local recurrence from its mimics.

    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: 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: 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.
