Superior MRI image quality (IQ) is indispensable for the radiologist to deliver an accurate diagnosis [3]. Lim et al. ME was a statistically significant predictor of good IQ (score 4, 5) for whole MRI IQ for R1 (b=1.09, OR 2.98 [95% CI 1.29, 6.87]) and R2 (b=1.01, OR 2.73 [95% CI 1.24, 6.04]), respectively.

T2W ( a , b ),, MeSH 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. Mp-MRI assesses water molecule motion (called water diffusion) and blood flow (called perfusion imaging) within the prostate. In many cases, MRI gives information that cannot be seen on an X-ray, ultrasound, or computed tomography (CT) scan. Multiparametric MRI (mpMRI) has become an invaluable tool in assessment of men at risk for prostate cancer [1, 2]. showed 12% of patients were stratified into a higher risk category using an mpMRI/TRUS fusion biopsy, and 18% were upgraded to intermediate or high risk from the low risk group.102 Panje et al. Results from mpMRI can be integrated into currently available clinical staging systems, and the information can be extrapolated to help risk stratify patients, guide therapy choice, and inform surgical technique.
