“…A sensitivity of 55-88% and 46-90% and a specificity of 67-82% and 74-96% were reported by different authors for T2WI and DCE-MRI, respectively. [8][9][10] The introduction of diffusion-weighted imaging (DWI) by measurement of the restriction of water diffusion of suspicious lesions has significantly improved the detection and localization of PCa in clinical practice.…”

Biparametric Magnetic Resonance Imaging (bpMRI) of the prostate combining both morphologic T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI) is emerging as an alternative to multiparametric MRI (mpMRI) to detect, to localize and to guide prostatic targeted biopsy in patients with suspicious prostate cancer (PCa). BpMRI overcomes some limitations of mpMRI such as the costs, the time required to perform the study, the use of gadolinium-based contrast agents and the lack of a guidance for management of score 3 lesions equivocal for significant PCa. In our experience the optimal and similar clinical results of the bpMRI in comparison to mpMRI are essentially related to the DWI that we consider the dominant sequence for detection suspicious PCa both in transition and in peripheral zone. In clinical practice, the adoption of bpMRI standardized scoring system, indicating the likelihood to diagnose a clinically significant PCa and establishing the management of each suspicious category (from 1 to 4), could represent the rationale to simplify and to improve the current interpretation of mpMRI based on Prostate Imaging and Reporting Archiving Data System version 2 (PI-RADS v2). In this review article we report and describe the current knowledge about bpMRI in the detection of suspicious PCa and a simplified PI-RADS based on bpMRI for management of each suspicious PCa categories to facilitate the communication between radiologists and urologists.

“…A total of 12 systematic reviews [11][12][13][14][15][16][17][18][19][20][21][22] were relevant and met the preplanned inclusion criteria; however, none of them covered both of the guideline objectives or used the same study selection criteria as ours. A total of 8663 original studies in English were identified and 15 were analyzed.…”

“…In a meta-analysis including a total of 698 patients with a previous negative prostate biopsy, the average sensitivity of DWI for detecting a carcinoma of the prostate is 38 % and the average specificity is 95 % [25]. The test quality parameters are slightly better for the combination of T2w images with DWI than for T2w images alone [26].…”

“…In MRI examinations with a field strength of 1.5 T, the application of a combined endorectal body phased-array coil is superior to the exclusive use of a phased-array coil without an endorectal coil with respect to image quality and local staging [26]. By using a combined endorectal body phased-array coil, the sensitivity and the positive predictive value for the detection of prostate cancer could be increased in individual studies even in 3 T MRI examinations [27].…”

The Working Group Uroradiology and Urogenital Diagnosis of the German Roentgen Society has developed uniform recommendations for the preparation and implementation of prostate MRI. In the first part detailed recommendations are given in tabular form regarding 1. anamnestic data before prostate MRI, 2. termination of examinations and preparation of examinations, 3. examination protocol and 4. MRI-guided in-bore biopsy. In the second part, the recommendations are discussed in detail and relevant background information is provided. Key Points: Citation Format

The Clinical Value of Diffusion-Weighted Imaging in Combination With T2-Weighted Imaging in Diagnosing Prostate Carcinoma: A Systematic Review and Meta-Analysis

Abstract: T2WI combined with DWI may be a valuable tool for detecting prostate cancer in the overall evaluation of prostate cancer, compared with T2WI alone. High-quality prospective studies of T2WI combined with DWI to detect prostate carcinoma still need to be conducted.
