Table 2: 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 -test with corresponding value and Pearson’s correlation coefficient with value. Intraclass correlation coefficient for interrater reliability and intrarater agreement.
