T2-weighted MR imaging is a non-invasive way for vasculitis
diagnosis. SPACE sequence has been successfully used for T1-weighted aortic
wall imaging. While its application in T2w aortic wall imaging
is hampered by the long scanning time, blood suppression performance
and physiological movement. In this study, three black blood methods with
optimized protocols have been tested and evaluated. Diffusion-Prepared SPACE
sequence with diastolic acquisition was proved to be a promising way for T2w
aortic wall imaging within a clinically acceptable acquisition time.
