| Research Abstract |
We performed a mathematical compartment model analysis with Tc-99m MIBI. A 2-compartment model was better than other model in our study. There were significant correlations between the rate constants and heart to mediastinum ratio. Therefore, the pharmacokinetics of Tc-99m MIBI might show the condition of myocardium. Moreover, the influx rate constant in patients with ischemic heart disease was reduced than it in normal control. This method might be useful to evaluate the condition of myocardial abnormality.
