The purpose of this study is to evaluate perfusion density of an old myocardial infarction using cardiac multidetector computedtomography (MDCT) with arterial phase. We included 56 patients with an old myocardial infarction who had undergonemedical treatment, primary angioplasty or bypass graft. Cardiac MDCT without stress perfusion was used for calculationof density of myocardial perfusion and global left ventricular function in patients was also analyzed according to initialand last follow-up echocardiography. All patients showed decreased perfusion in the left ventricular wall. Densities of normalventricular wall, cavity of the left ventricle, and infracted wall were 105±29 HU, 471±117 HU, and 11±29 HU (-64HU-57 HU), respectively. Subendocardial fat depositions were observed in 19 patients (34%). Ejection fractions of initialand last follow-up periods near to the date of cardiac CT were 61±9 % and 57±12 %, respectively. In conclusion, decreasedperfusion less than 60 HU in cardiac CT with arterial phase was helpful in diagnosus of an old myocardial infarction.
