Spatial variation in the background source distribution makes tumor detection difficult for single-detector probes. Using a single energy window that brackets the photopeak helps discriminate against background events dominated by Compton scattering.

The physical properties of three surgical probes containing different radiation detectors are compared: a NaI(Tl) scintillator with a flexible, fiber-optic light guide, and two semiconductor detectors that operate at room temperature, CdTe and HgI2.

All gallium-67 citrate scans obtained in patients with acquired immunodeficiency syndrome (AIDS) at the Clinical Center, National Institutes of Health (Bethesda, Md.) were retrospectively analyzed and correlated with the results of bronchoscopy, ches

Eleven patients with high-risk thyroid carcinoma of anaplastic or mixed anaplastic-differentiated histology were treated using an early multimodality approach. Patients were classified using the prognostic index for thyroid carcinoma developed by the

A hand-held, dual-detector probe has been developed for surgical tumor staging. This dual probe simultaneously monitors counts from a possible tumor site along with counts from adjacent normal tissue using two concentric, collimated scintillation det

We used an observer-performance study to compare four different modes of presenting count-rate data from a radiation detector. Observers searched for small, concealed radioactive sources using a hand-held radiation-detector probe. The modes of count-

Ligation of the splenic artery was performed upon six children with a variety of peripheral cytopenias associated with hypersplenism to decrease splenic hyperfunction while preserving some splenic tissue. While this procedure initially improved the p

Indium-111 attached to bleomycin is useful in the scintigraphic localization of a variety of tumors. Since it does not normally accumulate in bowel and feces, it is superior to other radiopharmaceuticals, such as gallium-67 citrate, in the demonstrat

The results of bone scanning with the newer technetium-99m complexes were correlated with clinical, laboratory, and radiographic findings in 26 patients with malignant lymphoma (10 with Hodgkin's disease and 16 with non-Hodgkin's lymphomas). Abnormal
