OBJECTIVES The purpose of this study was to determine how frequently and for what reasons the addition of electrocardiographically gated technetium-99m (Tc-99m) sestamibi single-photon emission computed tomographic (SPECT) images add value to nongated SPECT perfusion images. BACKGROUND Electrocardiographic gating of Tc-99m sestamibi SPECT images permits(More)
To compare the myocardial uptake pattern of 99mTc-labeled methoxyisobutyl isonitrile [( 99mTc] MIBI) and 201TI, planar scintigraphy were performed in both patients with documented coronary artery disease and subjects with a low likelihood of disease. Quantitative analysis was employed using a standard interpolative background subtraction algorithm and a new(More)
Sestamibi planar myocardial perfusion studies were performed at Hotel-Dieu de Montreal on 28 patients with documented coronary artery disease and 16 normal subjects. Stress and rest studies were performed on separate days. These studies were sent to Virginia for interpretation while blinded as to age, sex, and other clinical information. Studies were(More)
Mini-watermelon [Citrullus lanatus (Thunb.)] cultivars Valdoria and Vanessa were evaluated at 20, 30, 40, or 50 days after anthesis to determine maturity at harvest. Fruit circumference, weight, ground spot color, and number of senescent tendrils were measured as external indicators for each watermelon. Soluble solids content (SS), pH, and SS:total acid(More)
The present study used 51 patients in a prospective, crossover, blinded comparison of dipyridamole thallium-201 imaging and dobutamine echocardiography for (1) detection of coronary artery disease (CAD), (2) detection of inducible ischemia, and (3) determination of myocardial viability. The detection of CAD was based on quantitative defects on initial(More)
