[Evaluation of 99mTc-DTPA-HSA abdominal imaging of protein-losing gastroenteropathy].
Abdominal images were obtained after the intravenous injection of 99mTc-HSA-D in 8 patients with protein-losing gastroenteropathy (PLG). Six neck images and 7 abdominal images were obtained in 11 patients with ischemic heart disease as a control study. We evaluated all the images with respect to visualization, initial appearance time, and movement of abnormal radioactivity. In 7 of 8 patients with PLG, abnormal radioactivity in the intestine appeared from 10 min to 4 hours after injection, and moved 6 hours after injection. In 6 of 7 abdominal images of control cases, slight activity was observed in the alimentary tract 6 hours or 24 hours after injection. The thyroid was not visualized in any of the 6 cases. In conclusion, if radioactivity in the alimentary tract was first observed 6 hours or later after injection, the diagnosis of PLG may be difficult by this method alone. It still may be necessary to perform the alpha 1-antitrypsin test for the correct diagnosis of PLG.
