A rare scintigraphic phenomenon of “superscan” is considered – an abnormally high diffuse accumulation osteotropic radiopharmaceutical by all skeletal parts in combination with the absence kidney and tissue background imaging. This feature reflects a generalized bone system lesion metastatic, metabolic or hematological nature. We present clinical observation retrospective assessment data obtain...

Filling defects are often observed on 99mTc sulfur colloid liver scans. Hot spots are much less frequently seen. Superior vena cava syndrome is the most frequent cause of this finding. In this report 3 patients with S.V.C and budd - Chiari syndrome with HOT SPOT on liver scan are presented. Mechanisms of scintigraphic patterns are reviewed.

This study evaluated the diagnostic accuracy of case-based reasoning (CBR) to automatically detect significant coronary artery disease from dipyridamole 201Tl myocardial SPECT perfusion scintigrams. Methods: The study population included 240 patients (182 men, 58 women; mean age 6 SD, 61 6 12 y) on whom coronary angiography and perfusion scintigraphy were performed within 6 6 11 d of each other...

The transport and intralymphatic deposition of interstitially injected radiocolloid of suitable physical properties are medi ated through physiological processes and provide the means for obtaining scintigraphic images of drainage lymph nodes relevant to the injection site. In a large series of patients with breast carcinoma, high correlation has been shown between the internal mammary lymphosc...

Mucosa-associated lymphoid tissue (MALT) lymphoma has been established as a distinct entity among non-Hodgkin's lymphomas, and the most common primary site is the stomach. We describe scintigraphic findings in a patient with MALT lymphoma of the thyroid. A 71-year-old woman with Hashimoto's thyroiditis suffered from rapid cervical swelling, and ultrasonography and CT revealed a thyroid nodule. ...
