Clinical Evaluation of Left Ventricular Diastolic Function Using Phase-contrast Cine Cardiovascular Magnetic Resonance Imaging: A Comparison With Steady-state Free Precession Cine Cardiovascular Magnetic Resonance Imaging and Echocardiography

Abstract

Objective: We investigated a practical method using phase-contrast (PC) cine cardiovascular magnetic resonance imaging to estimate peak filling rate and early/atrial velocity (E/A) as left ventricular diastolic function indicators.

Methods: Peak filling rate and E/A were estimated in 32 patients using PC imaging with high spatial or high temporal resolution and compared with those estimated using steady-state free precession cine cardiovascular magnetic resonance imaging and echocardiography.

Results: Peak filling rate estimated using PC imaging significantly correlated with those estimated using steady-state free precession imaging despite apparent underestimation using PC imaging with high spatial resolution. The E/A estimated using PC imaging significantly correlated with those estimated using echocardiography.

Conclusions: Peak filling rate and E/A measurements using PC imaging with high temporal resolution is convenient and acceptably accurate, suggesting its potential for clinical use.
