To enable the detection of small ischemic lesions, the authors proposed a new "distance-subtraction” method: after suitable centering of the axial slices, 3D "distance-shaded” images of the stress study were subtracted from the corresponding views of the rest study. With this technique, small changes in surface-to-observer distance were highlighted, thus enabling us to detect nontransmural ischemic areas of the myocardium. General characteristics and possibilities of the subtraction technique were tested on a simple myocardial phantom. Some clinical results of the application of this method on CAD patients are presented and discussed. In CAD patients in whom only nontransmural ischemic lesions are present, the subtraction of "distance-shaded” images is decisive for a correct diagnosis.
