METHODS Thirty-two patients with clinical node-negative breast cancer underwent sentinel node localization study as part of a National Cancer Institute-sponsored multicenter trial. Anatomical and histopathologic characteristics of sentinel lymph node (SLN) and a kinetic analysis of nodal uptake were studied. Patients were injected with 1 mCi/4 ml unfiltered 99mTc-sulfur colloid in four divided ...

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.

Bone marrow infarction was investigated by 99mTc-sulfur colloid imaging in 42 patients with sickle cell anemia (SS) over a period of 2 yr. Marrow defects were demonstrated in 28 patients (66.6%), and in 15 (aged 19--52 yr), they were matched by roentgenographic evidence of medullary bone infarction. Repeated images showed no change in the size or site of these defects. Among 13 patients (aged 6...

Five cases are presented in which lesions affecting the spleen were suspected either clinically or on routine 99mTc-sulfur colloid liver scans. Using 99mTe, transmissionemission scans were performed on these patients; these scans were all abnormal. Sub sequent diagnostic studies confirmed three real lesions. The other two patients had intrathoracic abnormalities producing the abnormal scans. Th...

Intrarenal splenosis is very rare and its management is not well established. We present a patient in whom an enhancing left renal mass was incidentally detected on a Computerized tomographic (CT) scan, concerning for renal cell carcinoma. However, the lesion was determined to represent intrarenal splenosis, confirmed by Technetium-99m (99mTc) sulfur colloid scan and percutaneous biopsy, which ...
