Radionuclide assessment of peritoneovenous shunt patency.

Denver shunt patency can be easily assessed by sequential scintigraphy with a Gamma camera after an intraperitoneal injection of 99mTc sulphur colloid. If the shunt is patent, the tracer will be seen throughout the shunt upto it's opening into the right atrium. The following case report illustrates the application and usefulness of this procedure.
