WebGated emission scans were obtained over 42 cm of body length, including the thorax and upper abdomen, with 3 bed positions of 10 min each. Transmission scans were obtained after injection with the same bed positions of 3 min each. The trans-mission acquisition was not gated with respiration. The gated emission data were reconstructed by use of ... WebMethods and results: Separate acquisition, dual isotope ECG-gated SPECT was performed in 97 patients with a low likelihood of CAD (Group 1) and 46 patients with single-vessel CAD (Group 2). Mild CAD was defined by stenosis of 50-75% (Group 2a, n=22) and moderate to severe CAD was defined by stenosis >/=76% (Group 2b, n=24).
