During the last two decades, Magnetic Resonance Imaging (MRI) of the prostate has evolved to become a promising tool in preoperative evaluation of prostate cancer. Several studies have evaluated the radiological and histopathological correlation. However, the sensitivity and specificity in regard to staging have shown wide ranges and poor reproducibility. These discrepancies can be explained by difference in patient selection, MRI methods, and criteria used for diagnosis. More studies are therefore needed to evaluate the clinical impact of preoperative MRI in patients with prostate cancer.
