Optimal timing of imaging in gastric emptying scintigraphy for the detection of delayed emptying.

Objective: The purpose of this study was to evaluate a standard 4-h imaging protocol for gastric emptying scintigraphy (GES) in detecting delayed gastric emptying (GE).

Subjects And Methods: Gamma camera imaging was performed in the anterior and posterior views at 0, 0.5, 1, 1.

Myocardial ischemia in female patients with rheumatoid arthritis assessed with single photon emission tomography-myocardial perfusion imaging.

Background: Non-specific cardiac symptoms in female patients with rheumatoid arthritis (RA) could indicate early cardiovascular disease.

Materials And Methods: Myocardial perfusion imaging (MPI), with 99mTc tetrofosmin stress-rest single photon emission computer tomography (SPECT), in 13 RA female patients with atypical cardiac symptoms, was compared to 44 weight- and age-matched females with similar cardiac complaints (control group). Smoking, hypertension, diabetes mellitus, dyslipidemia, obesity and cardiac heredity were recorded and compared between the study and control group.
