Scrotal imaging.

Watanabe Y. Department of Radiology, Kurashiki Central Hospital, Kurashiki, Japan. Color Doppler
ultrasound has been the mainstay for the evaluation of the scrotum in a variety of clinical settings.
However, ultrasonography results are not always accurate or conclusive. Despite the high cost and
limited availability, magnetic resonance imaging with the dynamic contrast-enhanced subtraction
technique provides accurate information on morphology as well as blood flow. Infrared scrotal
thermography increases accuracy in the diagnosis of varicocele. This article attempts to summarize
recent advances in scrotal imaging with regard to testicular and extratesticular disorders.
