Abstract

PURPOSE: The aim of this study is to better understand the pattern and nature of reverse redistribution (RR) in myocardial perfusion imaging.
MATERIALS AND METHODS
In consecutive 20 acute myocardial infarction (MI) patients, frequency of RR was correlated with that of subendocardial MI that was detected by myocardial contrast echocardiography (MCE). RR was judged to be present when there was more than one grade of worsening in perfusion at 24 hr delayed images compared with the initial rest images. MCE evaluated the significant lack of opacification in the subendocardial myocardium relative to the subepi-cardial myocardium to suggest the subendocardial MI. Kendall's nonparametric correlation coefficiency was calculated.
RESULTS
Concordant cases were 15 of 20 (75%) and correlation was statistically significant (p=0.0285).
CONCLUSION
Our results suggested that RR was correlated with MCE-detected nontransmural MI.
