Blood Flow Vortices along the Main Pulmonary Artery Measured with MR Imaging for Diagnosis of Pulmonary Hypertension

Structured PICO

Does phase-contrast MR imaging of vortical blood flow in the main pulmonary artery allow accurate diagnosis of pulmonary hypertension?

Intervention

Phase-contrast MR imaging to measure duration of vortical blood flow in the main pulmonary artery

Outcome

Estimation of elevated mean pulmonary arterial pressure (mPAP) and diagnosis of pulmonary hypertension (PH)surrogate

Phase-contrast MR imaging of vortical blood flow in the main pulmonary artery provides a non-invasive method to accurately estimate elevated mPAP and diagnose pulmonary hypertension.

Abstract

Duration of vortical blood flow in the main pulmonary artery that is determined by using phase-contrast MR imaging allows accurate estimation of elevated mPAP and diagnosis of PH. Clinical trial registration no. NCT00575692.
