Pulmonary Vascular Disease Evaluation with Magnetic Resonance Angiography

Bradley D Allen et al. Radiol Clin North Am. 2020 Jul.

Abstract

Pulmonary vascular assessment commonly relies on computed tomography angiography (CTA), but continued advances in magnetic resonance angiography have allowed pulmonary magnetic resonance angiography (pMRA) to become a reasonable alternative to CTA without exposing patients to ionizing radiation. pMRA allows the evaluation of pulmonary vascular anatomy, hemodynamic physiology, lung parenchymal perfusion, and (optionally) right and left ventricular function with a single examination. This article discusses pMRA techniques and artifacts; performance in commonly encountered pulmonary vascular diseases, specifically pulmonary embolism and pulmonary hypertension; and recent advances in both contrast-enhanced and noncontrast pMRA.

Keywords: Magnetic resonance angiography; Pulmonary arteries; Pulmonary embolism; Pulmonary hypertension.
