Correlation of edematous mass as measured by the T2 SI ratio in patients with acute MI in different muscle groups with infarct mass (5SD LGE); differences as per paired t-test with corresponding P value and Pearson's correlation coefficient with P value. Intraclass correlation coefficient for interrater reliability and intrarater agreement.
