Rapid development or evolution of a nonenhancing adrenal mass or masses with an adreniform shape or high T1 signal intensity on MR images of a patient under stress or with a bleeding diathesis, including anticoagulant use, suggests acute adrenal hemorrhage. Chronic hemorrhage appears as a thin-walled pseudocyst or atrophy. Imaging findings that may indicate underlying tumor include intralesional calcification, enhancement, and hypermetabolic activity on PET images.

Longer PET acquisition times during PET/MRI for rectal cancer increases the number of FDG-avid lymph nodes detected without increasing scan time.

PI-RADS v2 is a strong predictor of CS-PCa in the non-academic setting and can be further strengthened when utilized with PSA density.

ADC values and categories help to diagnose CS-PCa when lesions are assigned a PI-RADS v2 score of 4.
