Key result
Velocity-encoded cine MR imaging enabled accurate and reproducible measurement of absolute blood flow in healthy subjects, correlating well with Doppler echocardiography.
Why the study?
Does velocity-encoded cine MR imaging accurately measure pulmonary blood flow compared to Doppler echocardiography?
Observational (n=9)
Does velocity-encoded cine MR imaging accurately measure pulmonary blood flow compared to Doppler echocardiography?
Velocity-encoded cine MR imaging with oblique-gradient flow encoding is an accurate and reproducible method for measuring absolute blood flow in the pulmonary arteries.

Supports MR flow quantification in healthy subjects; leaves open validation and clinical adoption in disease.
Caputo et al. (1991) conducted an observational in Healthy volunteers (n=9). Velocity-encoded cine MR imaging vs. Doppler echocardiography was evaluated on Measurement of oblique-angle flow velocity and volume. Velocity-encoded cine MR imaging enabled accurate and reproducible measurement of absolute blood flow in healthy subjects, correlating well with Doppler echocardiography.
