Key result
Phase-contrast cine MRI significantly correlated with steady-state free precession MRI and echocardiography for estimating peak filling rate and E/A in 32 patients.
Why the study?
The study investigated a practical method using phase-contrast cine cardiovascular magnetic resonance imaging to estimate peak filling rate and early/atrial velocity as left ventricular diastolic function indicators.
Does phase-contrast cine cardiovascular magnetic resonance imaging accurately estimate peak filling rate and E/A compared to SSFP cine CMR and echocardiography in patients?

Does phase-contrast cine cardiovascular magnetic resonance imaging accurately estimate peak filling rate and E/A compared to SSFP cine CMR and echocardiography in patients?
Phase-contrast cine CMR with high temporal resolution provides a convenient and acceptably accurate method for evaluating left ventricular diastolic function.
Provides preliminary support for phase-contrast cine CMR in diastolic assessment; leaves open prospective outcome validation in larger cohorts.
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.

Komi et al. (2021) conducted an observational in Left ventricular diastolic function evaluation (n=32). Phase-contrast cine cardiovascular magnetic resonance imaging vs. Steady-state free precession cine cardiovascular magnetic resonance imaging and echocardiography was evaluated on Peak filling rate and early/atrial velocity (E/A). Phase-contrast cine MRI significantly correlated with steady-state free precession MRI and echocardiography for estimating peak filling rate and E/A in 32 patients.
