The safety, clinical usefulness and the optimal dose of 123I-orthoiodohippurate (123I-OIH) were evaluated in patients with mild renal disorders. 123I-OIH was administered intravenously to 45 patients, and 39 of those patients were analyzed for the clinical usefulness. The numbers of cases analyzed were 10 for 9.25 MBq (0.25 mCi), 18.5 MBq (0.5 mCi) and 74(More)

We reported two patients with liver transplantation who are performed hepatobiliary scintigraphy in rejection. In one patient hepatobiliary scintigraphy shows dilatation of bile duct but it shows good clearance from liver. In another patient hepatobiliary scintigraphy shows delayed clearance from liver. Both patients recovered from rejection. There are four(More)
