BACKGROUND The delivery of a simultaneous integrated boost to the intra-prostatic tumour nodule may improve local control. The ability to deliver such treatments with hypofractionated SBRT was attempted using RapidArc (Varian Medical systems, Palo Alto, CA) and Multiplan (Accuray inc, Sunnyvale, CA). MATERIALS AND METHODS 15 patients with dominant(More)
Cancers arise from unregulated cellular growth and exhibits a range of pathophysiological characteristics and behaviour. The term " tumour heterogeneity " encompasses a broad range of tumour features that have arisen as a result of different mechanistic processes including stem-cell origin, tumour evolution (linked to genetic mutations and adverse tumour(More)
BACKGROUND AND PURPOSE Magnetic resonance (MR) and computed tomography (CT) images are degraded in the presence of metallic implants. We investigate whether SEMAC (Slice Encoding for Metal Artifact Correction) MR is advantageous for radiotherapy (RT) planning. METHODS Conventional and SEMAC MR protocols were compared (1.5T). A spine fixation device(More)
BACKGROUND To evaluate diffusion-weighted MR neurography (DW-MRN) for visualizing the brachial plexus and for the assessment of brachial plexopathy. METHODS 40 oncological patients with symptoms of brachial plexopathy underwent 1.5 T MRI using conventional MR sequences and unidirectional DW-MRN. The images were independently reviewed by two radiologists.(More)
Sarcomas of the prostate are rare tumours. Their clinicopathologic features are well described, however, the imaging features of these tumours have rarely been documented. The purpose of this article is to illustrate the imaging findings of prostate sarcomas, with an emphasis on their appearance on magnetic resonance imaging and to identify features that(More)
The growing use of cross-sectional imaging has led to increasing detection of incidental lesions that previously remained undiscovered. These incidental lesions are unexpected, usually asymptomatic and are not related to the patient's presenting complaint or past medical history. Incidental findings in the kidneys are common and most of them are renal(More)
