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. (Korean J Nucl Med
