Dual-isotope Tl/ I-MIBG SPECT can assess trigger zones (dysfunctions in the autonomic nervous system located in areas of viable myocardium) that are substrate for ventricular arrhythmias after STEMI. This study evaluated the necessity of delayed acquisition 201 123 and scatter correction for dual-isotope Tl/ I-MIBG SPECT studies with a CZT camera to identify trigger zones after revascularization in patients with STEMI in routine clinical settings. Methods. Sixty-nine patients were prospectively enrolled after revascularization to 201 123 undergo Tl/ I-MIBG SPECT using a CZT camera (Discovery NM 530c, GE). The
