Abstract

A quantitative method for external detection of mesenteric arteriovenous shunts was developed. 99mTc-Human Serum Albumin Microspheres (15-30 /n) were injected into the superior mesenteric artery of dogs through an angiographic catheter, followed by external scintillation counting of the liver activity, which represented the shunted spheres. Thereafter, 99mTc- sulfur colloid was injected identically and the liver activity counted again. The liver net count after sulfur colloid represented a 100% shunt, when a correction factor for the actual liver uptake was applied. Then a shunt rate was calculated. Eleven animal studies were performed and shunt rates similar to previous in vitro determinations were obtained. This method is suitable for clinical investigation and can conveniently be applied to mesenteric arteriography.
