[A case of myocardial infarction with ventricular tachycardia, which had discrepancy of defect size between 123I-MIBG and 201TlCl myocardial imaging].
123I-MIBG and 201TaCl myocardial imaging were carried out in 69 years-old man who had anterior myocardial infarction with ventricular tachycardia. In planar and SPECT imaging, the defect size of 123I-MIBG was larger compared to that of 201TlCl. The zone of fractionated activity was corresponded with the defect of 123I-MIBG. Thus, the denervated but viable myocardium could be detected by 123I-MIBG and 201TlCl myocardial imaging. 123I-MIBG may give a useful clinical information, since denervation may play a role in causing ventricular arrhythmia after myocardial infarction.
