ECG-gated 99mTc-MIBI SPECT was performed in 33 patients, including 17 normal subjects and 16 patients with old myocardial infarction. To compare the findings by echocardiography (UCG), regional wall motion was qualitatively assessed by cine-mode display and quantitatively measured as an increase in regional count from end-diastole to end-systole. The percent count increase and relative count increase was measured to display on the Bull's eye polar map. In the study of normal subjects, the count increase was greater in apical regions and smaller in septal regions. Regional wall motion by this method correlated well with UCG findings (agreement: 97%, complete agreement: 60%). A mild but significant correlation was observed between the count increase by this method and the percent wall thickening by UCG. We conclude that regional wall motion can be accurately evaluated with ECG-gated 99mTc-MIBI SPECT, which thus permits simultaneous assessment of regional wall motion and myocardial perfusion.
