AB  - The purpose of this study was to clarify the characteristics of black-blood 
      echo-planar imaging (BB-EPI) in the assessment of infarct-related myocardial 
      edema (IRME), compared with T2-weighted imaging (T2WI). Thirteen acute myocardial 
      infarction (MI) patients after reperfusion and 11 old MI patients underwent 
      BB-EPI and T2WI, excluding those with posterior MI. In acute MI patients, signal 
      intensity ratio (SI ratio) of edema to normal myocardium was measured. 
      Black-blood echo-planar imaging revealed hyperintensity in the same region 
      identified as IRME on T2WI in all acute MI patients, and SI ratio was 
      significantly higher in BB-EPI (2.66 +/- 1.58) than in T2WI (1.44 +/- 0.22) (P < 
      0.05). However, BB-EPI showed hyperintensity in posterior wall, where there is no 
      clinical evidence of acute MI, in 2 out of 13 acute MI patients. Both T2WI and 
      BB-EPI detected no IRME in known old infarct area of all old MI patients, but 
      BB-EPI showed hyperintensity in the posterior wall of 4 out of 11 old MI 
      patients. Black-blood echo-planar imaging can depict IRME with sufficient 
      suppression of background and blood flow signals, and with excellent 
      edema-to-normal myocardium contrast resolution. However, BB-EPI sometimes shows 
      an inconsistent signal area with T2WI specifically in posterior wall. The wide 
      practical use of BB-EPI requires the solution to this serious problem.
