“…This is significant for localizing the tumor in the prostate and is increasingly expected to help guide therapy. There are also recent data suggesting that multiparametric MRI may have a role in active surveillance of low-risk patients [7]. …”

Objective The purpose of this study was to systematically review and meta-analyze dynamic contrast-enhanced MRI (DCE-MRI) for the detection of prostate cancer in comparison with standard evaluation with T2-weighted imaging. Materials and Methods A PubMed electronic database search for the terms “dynamic contrast-enhanced,” “prostate,” and “MRI” was completed for articles up to September 17, 2013. All included studies had histopathologic correlation. Two by two contingency data were constructed for each study. A binormal bayesian ROC model was used to estimate and compare sensitivity, specificity, and AUC among eligible modalities. Results Both DCE-MRI (0.82–0.86) and diffusion-weighted MRI (DWI) (0.84–0.88) yielded significantly better AUC than T2-weighted imaging (0.68–0.77). Moreover, partial AUC for the combination of DCE-MRI, DWI, and T2-weighted imaging was improved significantly (0.111; 0.103–0.119) when compared with DCE-MRI alone (0.079; 0.072–0.085) and T2-weighted imaging alone (0.079; 0.074–0.084) but not DWI alone (0.099; 0.091–0.108). Sensitivity and specificity were similar among the four modalities. Conclusion DCE-MRI improves AUC of tumor detection overall compared with T2-weighted imaging alone. Methods for DCE-MRI analysis require standardization, but visual analysis performs similar to semiquantitative methods. A two-parameter approach using DCE-MRI and T2-weighted imaging or DWI and T2-weighted imaging may be sufficient, and the latter may be more favorable for most routine prostate cancer imaging.

“…Since these characteristics are different for malignant and benign tissues, highresolution mpMRI provides valuable data that helps characterize the extent and biological behavior of prostate cancer. Owing to these capabilities, MR imaging of the prostate is increasingly being used to assist patients and clinicians to make management decisions [4][5][6][7][8].…”

Practical aspects of prostate MRI: hardware and software considerations, protocols, and patient preparation

et al. 2015

View full text Add to dashboard Cite

The use of multiparametric MRI scans for the evaluation of men with prostate cancer has increased dramatically and is likely to continue expanding as new developments come to practice. However, it has not yet gained the same level of acceptance of other imaging tests. Partly, this is because of the use of suboptimal protocols, lack of standardization, and inadequate patient preparation. In this manuscript, we describe several practical aspects of prostate MRI that may facilitate the implementation of new prostate imaging programs or the expansion of existing ones.
