Summary

Radionuclide imaging is now commonly used for assessing patients with ischemic heart disease. Myocardial SPECT imaging with technetium-99m labeled perfusion agents is especially useful since regional myocardial perfusion and function are simultaneously estimated by using ECG-gated acquisition. In the present study, we developed two kinds of software program for image processing in the ECG-gated imaging. One is to quantify regional wall thickening of the left ventricle on the basis of changes in regional myocardial radioactivity from end-diastole to end-systole. The other is to generate a superimposed display of three-dimensionally reconstructed coronary artery trees and myocardial SPECT images. We evaluated utilities of these two software programs to the decision-making and effect-evaluation of coronary revascularization therapies in patients with ischemic heart disease and found promising roles in the clinical care.
