AB  - OBJECTIVES: To investigate whether subendocardial and transmural myocardial 
      infarction can be identified and differentiated using the peak circumferential 
      and longitudinal strains measured by fast strain-encoded (SENC). METHODS: 
      Nineteen patients with ischemic heart diseases underwent imaging with fast SENC 
      and late gadolinium enhancement (LGE) MRI at 3 T. Fast SENC measurements were 
      performed in three short-axis slices (basal, mid-ventricular and apical levels) 
      and one long-axis view (four-chamber) to assess peak longitudinal and 
      circumferential systolic strains. RESULTS: All patients showed myocardial 
      infarction with an average of 7 positive LGE segments. A total of 304 segments 
      for longitudinal strains (LS) and 114 segments for circumferential strains (CS) 
      could be analysed. Positive LGE segments showed lower peak CS and LS compared 
      with the no LGE segments (P < 0.0001 for both). Segments with subendocardial 
      infarction showed reduced CS and LS compared with the no LGE segments (P < 0.0001 
      for both). There was a significant difference in CS between subendocardial and 
      transmural infarct segments (P = 0.03), but no significant difference in LS 
      between them (P = 0.64). CONCLUSIONS: Fast SENC can identify old myocardial 
      infarction and differentiate subendocardial from transmural infarction.
