Abstract :
In patients with coronary artery no simple relation exists between the visually or quantitatively evaluated severity of coronary artery stenoses and its effects on regional myocardial perfusion. We described 3D technique that visualizes and quantifies regional myocardial perfusion parameters from biplane coronary angiograms by using the impulse response analysis technique and combine it with 3D structure of coronary tree as an “integrated” 3D image. This 3D fusion image may provide useful information in evaluation of hemodynamic consequence of coronary lesions on myocardial perfusion
