ROLE OF MRI IN STAGING OF PROSTATIC CANCER BASED ON PIRADS CLASSIFICATION VERSION 2

Abstract

Prostate cancer is the most common cancer in elderly males, affecting mainly lifestyle with risk of morbidity rather than affecting the lifetime (low mortality rate). MRI examination of the prostate gland has a high specificity and sensitivity in primary diagnosis or staging over clinical assessment alone (PSA level and DRE), and other modalities like ultrasound. mp-MRI is considered the best anatomical and functional imaging modality that is used for detection and characterization of prostate tumors and for clinical staging of patients with prostate cancer, including (T1, T2 and DWI & ADC). Despite prostatic biopsy is still the gold standard technique in diagnosis of prostate cancer. The combination of multi-parametric MR and prostatic biopsy is very beneficial, as mp-MRI will add multiple advantages like reduced risk of re-biopsy and associated complications, evaluated extra-capsular spread which is the most important factor in treatment planning of prostate carcinoma.
