European researchers at the ECR last week, defended the use of MR for lung imaging. They proposed different protocols that would take from 15 to 25 minutes. The wide variety of lung MRI techniques was set out by Dr. Jim Wild, a medical physicist at the University of Sheffield in the U.K. His checklist included standard proton MRI, oxygen-enhanced imaging, contrast-enhanced pulmonary angiography, perfusion imaging, and hyperpolarized gas MRI (helium and xenon).
CT angiography would still be preferred in the acute setting, owing to the logistics of MRI. Either MRI or CT could be used when assessing patients with chronic pulmonary vascular disease. In the case of congenital abnormalities, MRA and MR perfusion imaging are the best choice.
