Figure 3 Correlation between dobutamine echocardiography and thallium single-photon emission computed tomography (Tl-SPECT) in a patient demonstrating nontransmural infarction in the apical septum (long arrow) and transmural infarction of the apical lateral segment (short arrow) by contrast-enhanced magnetic resonance imaging (ceMRI). The resting echocardiogram shows akinesia of both segments, and Tl-SPECT shows a severe perfusion defect.
