[Three-dimensional assessment of myocardial blood flow and glucose metabolism using oblique-angle tomograms and polar map displays of cardiac PET images].
To evaluate clinical value of three-dimensional assessment of cardiac PET image, oblique-angle tomograms and polar map displays were reconstructed from transaxial PET images using 18F-2-fluoro-2-deoxyglucose and 13N-ammonia in 19 patients with coronary artery disease. Short-axis and vertical long-axis images enabled to evaluate extent and severity of perfusion abnormality easily in the anterior and inferior regions which were tangential in the transaxial images. Using polar map displays, perfusion/metabolism mismatch may be more easily assessed. Thus, semiquantitative analysis of ischemic and infarcted myocardium may be permitted with PET studies.
