Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the study was to examine the influence of external beam radiation on the prostate and prostate cancer using novel quantitative MRI techniques. Twenty-two men, previously diagnosed with prostate cancer, were studied using T1 and T2 relaxation mapping and contrast agent kinetic methods before and after treatment by radiotherapy. The MRI findings will be correlated with biochemical (prostate specific antigen) progression and biopsy results. All 22 patients have been recruited and studied pre-treatment. So far nineteen patients have returned for follow-up MRI. The data is both complete and of a high quality. Data analysis of the pre-treatment phase has provided important and novel information about the microvascular characteristics of prostate cancer. These results have been accepted for publication in the leading radiology journal. Preliminary analysis of the post- treatment data is promising and awaits clinical interpretation.
