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)
RATIONALE AND OBJECTIVES To assess if ferumoxtran-10 (f-10) improves accuracy of MRI to detect lymph node (LN) metastasis in advanced cervical cancer. MATERIALS AND METHODS F-10 MRI component of an IRB approved HIPAA compliant ACRIN/GOG trial was analyzed. Patients underwent f-10 MRI followed by extra-peritoneal or laparoscopic pelvic and abdominal(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)
