title: Foot pedal-activated injector for contrast-enhanced sonography.
abstract: We assessed the feasibility and convenience of an injector that is electrically activated by a foot pedal for contrast-enhanced sonography. Thirty-seven patients with liver lesions underwent contrast-enhanced sonography using an injector that is activated by a foot pedal. The contrast agent was injected by pressing the foot pedal. All the studies were successfully performed without complications. The device enables the sonologist to keep the probe stationary during the injection and avoids the need for additional personnel. Pedal activated injection is a safe, useful, and convenient method of contrast-enhanced sonography.
