Real-time ultrasound. A new method for studying gall-bladder kinetics

Abstract

Real-time ultrasound is a satisfactory method for studying changes in human gall-bladder size. It is superior to many other methods since it is non-invasive, harmless and does not rely on the metabolism of a contrast agent. It is also easy to identify and to compensate for changes in the gall-bladder axis. Rapid serial images are easily obtained and show similar contraction patterns to those resulting from conventional techniques.
