FIGURE 4. Left ventricular functional images obtained by ECG-gated myocardial SPECT from same patient as in Figure 3. Outer cage and solid surface represent endocardial surfaces at end-diastole and end-systole, respectively. In initial images, anteroapical wall, septum, and lateral wall were hypokinetic and inferior wall was akinetic. In reinjection images, anteroapical wall, septum, and lateral wall were normokinetic and inferior wall was akinetic. Worsening of regional wall motion was observed in anteroapical wall, septum, and lateral wall. These findings suggested left anterior descending artery disease and left circumflex artery disease.
