Abstract:
Purpose To compare the similarity between the short-axis left ventricular cavity fractional area change measured by cardiac magnetic resonance and myocardial circumferential strain.Materials and Methods Forty cases of cardiomyopathy with different phenotypes and high-quality cardiac magnetic resonance images in PACS data center of the Sixth Medical Center of Chinese PLA General Hospital were retrospectively selected.All patients underwent cine imaging on a 3.0T MRI scanner.The endocardial and epicardial areas of each short-axis left ventricular slice were measured using Medviso Segment software to calculate slice-level fractional area change and global fractional area change.Slice circumferential strain and global circumferential strain were measured using Circle CVI42 software.Linear regression analysis was performed to assess correlations between global circumferential strain and global fractional area change,as well as slice circumferential strain and slice-level fractional area change.Results Both global circumferential strain and global fractional area change,as well as slice circumferential strain and slice-level fractional area change,exhibited positive correlations(all r>0.95).Linear regression demonstrated significant relationships(regression coefficients:2.40-3.16,P<0.05),with coefficient magnitudes related to left ventricular cavity radius.After normalization,circumferential strain and fractional area change curves showed identical standard deviations.Conclusion Short-axis left ventricular cavity fractional area change and myocardial circumferential strain display significant positive correlations at both slice and global levels,with similar curve morphology.These findings suggest that circumferential strain and fractional area change possess comparable statistical value in assessing cardiac function.
