Assessment of Pulmonary Perfusion With Ultrafast Projection Magnetic Resonance Angiography in Comparison With Lung Perfusion Scintigraphy in Patients With Malignant Stenosis

Abstract

Pulmonary perfusion could be demonstrated by using an ultrafast 2D projection MR DSA sequence. This technique allows measurement and quantification of pulmonary perfusion abnormalities in patients with malignant stenosis with statistically significant correlation to perfusion scintigraphy. The diagnostic potency in the evaluation of malignant pulmonary artery stenosis compared with conventional DSA could be shown.
