Nucl. Med. Technol.1985 Mar 01; 13 AB - This paper presents a method used to evaluate solid and liquid phase markers for radionuclide gastric emptying studies. We conducted in vitro and in vivo comparative experiments employing several radiolabeled markers. Among the solid phase markers tested, Tc-99m-sulfur colloid in vivo-labeled liver and I-131-fiber performed optimally. However, Tc-99m sulfur colloid in scrambled egg showed very acceptable performance and it is significantly easier to prepare. Among liquid phase markers, we found In-111-DTPA stabilized with 1% albumin to be a good agent and appropriate for dual isotope emptying studies.
