technetium-tc-99m-gluceptate and Contusions

Unilateral focal areas of intense, increased renal uptake of Tc-99m oxidronate sodium (technetium-99m HDP) were incidentally detected in the bone scan of a female patient who subsequently gave a history of recent trauma to her flank. Increased renal parenchymal uptake of Tc-99m HDP in this patient was thought to be due to kidney contusion. The case is interesting in itself and for its possible implications regarding the use of radio-labeled phosphate compounds for detection of renal contusion.

The diagnosis of renal trauma for many years was achieved through history, clinical findings, the performance of a survey film of the abdomen, urinalysis, excretory urography, aortography, and selective renal artery arteriography. The development of the scintillation camera and the availability of 99mTc, as well as 99mTc labeled pharmaceuticals, approximately fifteen years ago has widened this diagnostic horizon. Exquisite new imaging modalities have become available recently. As a result of constantly improving technology, these techniques--including computed tomography, sonography, with real time enhancement, and digital video subtraction angiography--are utilized more and more frequently. The full impact of these newest wonders is not yet realized. Cost-effectiveness, radiation exposure, accumulative drug side-effects, availability of facilities and personnel and professional and technical training have become major considerations.
