Sonographic evaluation of acute intrascrotal pathology.

High-resolution, real-time sonography is commonly used for the evaluation of acute scrotal pathology. Pulsed and color Doppler techniques enhance diagnostic accuracy [1, 2]. However, extensive distortion of intrascrotal anatomy can occur with advanced inflammation, infarction, or trauma, leading to decreased specificity of the sonographic examination.

Surveillance of infrainguinal vein grafts with duplex sonography.

This review considers the relative roles of traditional noninvasive vascular tests and conventional duplex and color flow Doppler sonography in the surveillance of infrainguinal autologous vein grafts. The purpose of surveillance is to identify significant anatomic or flow abnormalities that predispose to thrombosis, but can be repaired before graft thrombosis occurs. Although a few authors believe that serial measurements of the ankle-brachial index and other noninvasive vascular tests can serve as the primary method of surveillance for infrainguinal grafts, most authors do not concur.
