BACKGROUND The uptake of F-18 deoxyglucose into dysfunction segments after myocardial
infarction identifies metabolically active (FDG+) or inactive (FDG-) myocardium. Although …

A 82Sr/2Rb generator (Squibb Diagnostics, Inc) provided • 2Rbeluted with a 0.9% NaCl
aqueous solution. The activity was infused into the patient by a microprocessor controlled …

Conclusion: This study demonstrates that FDG-PET is more sen sitive than sestamibi-
SPECT in the preoperative localization of parathyroid adenomas in patients with primary …

The utility of computed tomography (CT) in the study of the anatomy, physiology, and pathology
of the human body has been the subject of considerable interest since the introduction of …

Brain imaging is performed using radiopharmaceuticals by single photon emission
computed tomography (SPECT) and positron emission tomography (PET). SPECT and PET …

Positron emission tomography (PET) requires positronemitting radionuclides that emit 511-keV
photons detectable by PET imagers. Positron-emitting radionuclides are commonly …

The extent of ischemic and hibernating myocardium, which may be detected by increased
postexercise uptake of fluoro-18 deoxyglucose (FDG) using positron emission tomography, …

A variety of periodic and aperiodic psyiologic motions affect the quality of CT images. This
study was initiated to estimate what an optimal scan period should be in the design of CT units…

The white and gray matter of the brain can be clearly differentiated by computed tomography
(CT). The differentiation is enhanced by the administration of contrast material. Without …

SPECT and PET were measured and compared. Both SPECT and PET studies were performed
in two groups of 18 patients each, with Group I using HE SPECT and Group II using UH …
