  • We evaluated 85 cases with atrophy of left lobe among 11,133 cases performed liver scan using $^{99m}Tc-phytate$ from January 1984 to January 1990 at Kyungpook National University Hospital in association with underlying causes and related conditions. Seventeen cases seemed to be due to biliary tract diseases, eg, cholelithiasis, cholangiocarcinoma, clonorchiasis and postcholecystectomy state. Fifteen cases were patients with primary and metastatic hepatic malignancies. One case had a history of hepatic irradiation. Thirty cases comprised acute hepatitis, chronic hepatitis, liver cirrhosis and fatty liver. However no causative abnormalities could be detected in 22 cases despite of meticulous diagnostic work-up.

  • Tetrofosmin is a ligand that forms a lipophilic, cationic complex with Tc-99m. Tc-99m tetrofosmin was developed as a myocardial perfusion imaging agent and also used to depict tumors. Mediastinal tumors is also detected by Tc-99m tetrofosmin. We report a case of extracardiac mediastinal activity detected by Tc-99m tetrofosmin scintigraphy, which revealed thymoma.

  • Radionuclide therapy has been an important field in nuclear medicine. In radionuclide therapy, relevant evaluation of Internally absorbed dose is essential for the achievement of efficient and sufficient treatment of incurable disease, and can be accomplish by means of accurate measurement of radioactivity in body and its changes with time. Recently, the advances of nuclear medicine imaging and multi modality imaging processing techniques can provide change of more accurate and easier measurement of the measures commented above, in cooperation of conventional imaging based approaches. in this review, basic concept for internal dosimetry using nuclear medicine imaging is summarized with several check points which should be considered In real practice.
