“…On MRI, CaP is typically intermediate in signal intensity on T1‐weighted images and low in signal intensity on T2‐weighted images relative to the normal peripheral zone (35–38). Low signal intensity within the peripheral zone on T2‐weighted images, however, also can be seen in other non‐neoplastic aetiologies, such as prostatitis, post‐biopsy haemorrhage, post‐radiation fibrosis and following hormonal therapy (39–41). Despite the non‐specificity of MRI, endorectal MRI combined with large field‐of‐view pelvic MRI with a body surface coil sorts patients into two groups: those who are potential surgical candidates and those who are not (39, 41).…”

“…Evaluation of transitional zone CaP with MRI is more difficult, as the central gland (often with BPH) has a greater percentage of fibrous stroma than the peripheral zone, which results in heterogeneous and lower T2‐weighted signal intensity (39, 45, 53).…”

“…The large array of techniques, including T1-weighted images, T2-weighted images, dynamic contrast enhanced (DCE) T1-weighted images, MR spectroscopy, diffusion weighted images and others, provides many opportunities to evaluate biologic processes. For prostate cancer, T2-weighted images are currently the most commonly used technique [33,34].…”

Management decisions for patients with prostate cancer present a dilemma for both patients and their clinicians because prostate cancers demonstrate a wide range in biologic activity, with the majority of cases not leading to a prostate cancer related death. Furthermore, the current treatment options have significant side effects, such as incontinence, rectal injury and impotence. Key elements for guiding appropriate treatment include: distinction of organ-confined disease from extracapsular extension (ECE); and determination of tumor volume and tumor grade, none of which have been satisfactorily accomplished in today's pre-treatment paradigm. Magnetic resonance imaging (MRI) has the capability to assess prostate tissue, both functionally and morphologically. MRI as a staging tool has not shown enough consistency or sufficient accuracy for widespread adoption in clinical practice; yet, recent technical developments in MRI have yielded improved results. At our institution we have combined the use of new endorectal 3 Tesla MRI technology, T2-weighted, and high spatial resolution dynamic-contrast enhanced (DCE) MRI to non-invasively assess the prostate with higher signal-to-noise ratio and spatial resolution than previously achieved. This approach allows assessment of prostate-tissue morphology and kinetics, thus providing a non-invasive tool for tumor detection and staging and, consequently, directing biopsy and treatment specifically to diseased areas for a pre-treatment evaluation that can assist in the rational selection of patients for appropriate prostate cancer therapy.
