ABSTRACT
Phase and Amplitude Image were developed to overcome the subjective nature of interpretation for cinematic endless loop display of radionuclide gated blood pool scan. To evaluate the usefulness of color coded phase image in coronary artery disease, we conducted a clinical study with coronary angiography and phase image in 23 patients, and compared the results of those studies. 1) The results of coronary angiography revealed normal coronary artery in 6, 1 vessel disease in 11, 2 vessel disease in 4, and 3 vessel disease in 2 patients. 2) Color-coded Phase Image revealed abnormal phase area in 2/2(100%) of 3 vessel disease patients and in 3/4(75%) of 2 vessel disease patients, in 5/11(45%) of 1 vessel disease patients, and only 1/6(16%) of normal coronary artery. 3) Among the patients who disclosed abnormal phase image, 5 patients of 2-or3-vessl disease revealed abnormal phase through whole left ventricular area, but 3 patients with right coronary artery lesion and 2 patients with left antrior descending artery lesion showed localized abnormal phase area, infero-apical and anterior portion respectively, which were in accord with each coronary lesion. We concluded that the phase image may be useful in evaluation of the regional wall motion abnormalities in the patients of coronary artery disease. Further studies seem to be neccessary to clarify the sensitivity and specificity of the phase image in the each disease entity group.
