Velocity-encoded MRI distinguishes high pulmonary vascular resistance in early study

Velocity-encoded MR imaging can be helpful for the measurement of hemodynamic parameters in patients with chronic pulmonary hypertension, posit clinicians at Hopital Broussais in Paris. Cardiac output and pulmonary vascular resistance (PVR) were measured in 19 patients through catheterization of the right side of the heart. Velocity-encoded MR provided accurate pulmonary arterial blood flow measurements, allowing practitioners a way to distinguish high PVR from normal PVR.
