| Research Abstract |
Myocardial perfusion of the whole heart obtained by SPECT (Single Photon Emission Computed Tomography) can be expressed using a single disc, i.e., Bull's Eye Map. When myocardial hypo-perfusion area is depicted, clinicians estimate the responsible coronary artery visually using the Bull's Eye Map. Recently, multi-slice CT has become able to offer clear coronary artery imaging. And the coronary tree can be superimposed into the Bull's Eye Map. Using this superimpose technique in 20 patients, we generated the borderlines of the coronary arteries (LAD : left anterior descending artery, LCX : left circumflex artery, and RCA : right coronary artery. Using the Bull's eye map with the borderlines of the coronary territories, responsible coronary arteries will be estimated more accurately.
