technetium-tc-99m-gluconate and Postoperative-Complications

Scintigraphy, ultrasound and magnetic resonance imaging were undertaken within three days on 73 patients who had had renal transplantation. Clinical and histological criteria were used to assess the ability of diagnosing rejection of the transplant. In all instances of rejection cortex-marrow differentiation was absent on magnetic resonance (MR) imaging; there were no false-negative results. Sensitivity as to rejection was 100% for MR imaging, 58% for scintigraphy and 32% for ultrasound. It may be possible to distinguish between cytomegalovirus infection and rejection reaction by MR imaging. It is concluded that MR imaging is the most reliable method for predicting rejection reactions, while ultrasound and scintigraphy are valuable for making other diagnostic decisions.
