• Gleason scores influence diagnostic performance of MRI for prostate cancer detection. • Addition of DWI does not improve low risk prostate cancer detection. • Combined T2WI and DWI may help select intermediate or high risk patients.

POHL development is associated with increased number of OBC sessions, and POHL severity was correlated with various biomarkers of SOS.

CIFH should be considered a mimicker of metastasis in patients with gastrointestinal malignancy during chemotherapy. CIFH can be differentiated from metastasis on the basis of gadoxetic acid-enhanced MR and DW imaging findings; an ill-defined margin on HBP images was especially characteristic.

The proposed MR classification is useful to predict a disc with concordant pain. Disc protrusion with HIZ on MR imaging predicted positive discography in patients with discogenic low back pain.

Institutional review board approval and informed consent were obtained. The purpose of the study was to prospectively evaluate magnetic resonance (MR) urethrography for the depiction of obliterative urethral stricture. Twelve patients with obliterative urethral stricture were examined preoperatively with T2-weighted, T1-weighted, and contrast material-enhanced T1-weighted MR imaging of a urethra distended with sterile lubricating jelly. Ten of the 12 patients were examined with conventional retrograde urethrography (RGU) combined with voiding cystourethrography (VCUG) prior to MR imaging. Each imaging result was compared with either a surgical specimen or a description of the surgical findings to determine which method allowed accurate estimation of stricture length. MR measurements of stricture length demonstrated significantly lower errors (P < .05) and better linear fit to surgical measurement than did conventional RGU combined with VCUG measurements (r(2) = 0.85, P < .001 and r(2) = 0.03, P > .05, respectively). MR imaging of the urethra distended with sterile lubricating jelly is an effective tool for evaluating obliterative urethral strictures.
