Defect of 18F-FDG Uptake Observed in Infarcted Myocardium Showing Reverse Redistribution on Rest / 24-Hour Delayed 201Tl Myocardial SPECT after Acute Myocardial Infarction / 핵의학분자영상

ABSTRACT

Reverse redistribution is frequently observed after revascularization in acute myocardial infarction, and usually regarded as a predictor of viable myocardium on stress/rest and 2- to 4-hour redistribution 201Tl SPECT. However, there is not enough report of reverse redistribution in case of 24-hour delayed SPECT, which is commonly used for viability assessment. In this report, a case of reverse redistribution on rest and 24-hour delayed 201Tl SPECT is reported with use of automatic segmental quantitative analysis. The myocardium of reverse redistribution was dysfunctional on gated SPECT, and diagnosed as non-viable on 18F-FDG PET.
