Methods:Twenty-nine patients (21 males,8 females;62±11 yrs) with recent AMI were studied.Within 6 days after AMI, the patients were performed Tl-201 R-RD perfusion SPECT using 4 mCi activity.CMR was carried out 5-20 minutes after 0,15 mmol/kg of iv.Gadobutrol injection.Myocardial perfusion and contrast enhancement was analyzed using a 17 segment model.Myocardial perfusion was scored in Tl-201 SPECT as follows:0=normal (70%-100% maximal myocardial activity(mma), 1= 69-50% mma, 2= 49-30% mma ,3=29-10% mma and 4=<10% mma ;Myocardial contrast enhancement on CMR images was graded as:0=no contrast enhancement, 1=hyperenhancement of 0-25% of the wall thickness(WT) 2=hyperenhancement of 26-50 % of the WT, 3=hyperenhancement of 51-75 % of WT and 4=hyperenhancement of 76-100 % of WT.In CMR the existence of microvascular obstruction(MO) was also evaluated.Total segment scores(TSS) in R,RD and CMR for each patient were calculated by summing of 17 segment score values.	./cache/cord-015354-yknwveyz.txt	./txt/cord-015354-yknwveyz.txt
