Multiparametric MRI (mpMRI) has become an invaluable tool in assessment of men at risk for prostate cancer [1, 2]. The increase in DWI IQ translated into significantly better perception of overall IQ of the whole mpMRI exam and logistic regression analysis revealed ME as the single significant predictor of good whole MRI IQ. Finally, despite the fact that HBB and ME are very often used simultaneously, no study investigated the effect of those techniques in combination or the specific contribution of one intervention alone regarding IQ in prostate MRI. an enlarged prostate congenital abnormalities Population: Lim et al. Depending on the type of MRI machine being used, your feet might go in first with your head and neck outside the scanner or vice versa. Despite this conclusion, significant opportunities exist for further refinement of active surveillance protocols to better risk-stratify men at initial entry into these protocols and to better target the regions of the prostate that could harbor a malignancy that would require a delayed therapeutic intervention.
