MR of the thoracic aorta: a pulse sequence approach to discrete feature analysis.

Abstract

Magnetic resonance (MR) imaging is a reliable tool for the depiction of the thoracic aorta. By combining traditional T1-weighted spin echo pulse sequences with newer MR angiography techniques, MR imaging can provide both the structural and functional information necessary to manage most thoracic aortic abnormalities. This article reviews the various MR pulse sequences germane to aortography, highlighting their technical considerations and clinical applications. Newer MR techniques for vascular imaging are also introduced.
