  		FIGURE 1. Assessment of LV shape using the sphericity index of gated SPECT. Bold lines represent tracing of LV contours using quantitative gated SPECT algorithm on end-diastolic images. Lines with arrowheads represent measurements of the long and vertical axes of the left ventricle. L = long axis of left ventricle; V = vertical axis of left ventricle.

  		FIGURE 2. Representative gated SPECT images from good responders (A) and poor responders (B). Shown are ungated perfusion polar maps before therapy (left panels) and serial 3-dimensional displays of end-diastolic (grid) and end-systolic (solid) surfaces from a right anterior oblique 30° view (middle and right panels). Small perfusion defects are present in apical and posterior myocardium of good responders (extent of defect, 4%). Three-dimensional displays show that LV shape is preserved as a prolate ellipse (sphericity index, 1.7). LVEF increased by 33% after ß-blocker therapy. In contrast, multiple perfusion defects were observed in poor responders (extent of defect, 11%) and the LV cavity is spheric (sphericity index, 1.3). LVEF increased by only 6% after 4 mo of ß-blocker therapy.
