SCINTISCAN DEMONSTRATION OF LOCALIZED BOWEL LOOP INFLAMMATION - COMPARISON OF TC-99M DEXTRAN, TC-99M CITRATE, AND TC-99M HUMAN-IMMUNOGLOBULIN-G

A 60-year-old man with localized small bowel inflammation underwent ab dominal scintigraphy with Tc-99m human polyclonal immunoglobulin G and two experimental inflammation-seeking agents, Tc-99m dextran and Tc-9 9m citrate. The abnormal loop was visualized in all the three studies, Additionally, the Tc-99m dextran study revealed exudation and luminal transit of the tracer suggestive of regional protein-losing enteropat hy, The authors conclude that Tc-99 dextran and Tc-99 citrate are clin ically suitable inflammation-seeking agents that need further evaluati on, especially for locating abdominal inflammations.
