title: Real-time ultrasound. A new method for studying gall-bladder kinetics.
abstract: Real-time ultrasound has been found to be a satisfactory method for studying changes in 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. We have also found it easy to identify and 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.
