Value of contrast-enhanced, balanced cine-MR sequences in the assessment of apparent infarct size after acute myocardial infarction: a prospective comparison with delayed-enhancement sequences.
OBJECTIVE
To evaluate the diagnostic value of contrast-enhanced (CE) delayed cine steady-state free precession (SSFP) sequences in the assessment of apparent infarct size after acute myocardial infarction (MI).


METHODS
Contrast-enhanced (CE) balanced cine-SSFP sequences were compared with delayed-enhancement (DE) T1 sequences for their ability to detect segmental abnormal enhancement in 29 consecutive patients with recent successfully reperfused acute MI.


RESULTS
The extent of myocardial involvement revealed by postcontrast cine-SSFP sequences and DE images was closely correlated (Spearman r = 0.86, P < 0.001). There was no significant difference between the two sequences in assessing subendocardial or transmural involvement.


CONCLUSIONS
In addition to DE sequences, CE cine-SSFP sequences should play a role in assessing necrotic and jeopardized myocardium after acute MI.
