Is apparent diffusion coefficient value a strong predictor of unsuspected aggressiveness of prostate cancer before radical prostatectomy?
Decreasing ADC value is a stronger indicator of aggressive prostate cancer as defined by molecular markers or postsurgical histology than biopsy characteristics.
When CTA is indeterminate in blunt thoracic trauma, conventional angiography is unlikely to show an aortic or intrathoracic great vessel injury and may be unnecessary. A grading system for mediastinal hematomas could help triage patients to conventional angiography when further imaging is desired.
