1 From the Department of Radiology, Northwestern University Medical School, 676 N St Clair St, Suite 800, Chicago, IL 60611 (F.S.P., R.M.M., V.B., J.C.C., V.K., J.P.F.); and University of Arizona Health Sciences Center, Tucson (E.A.K.). From the 2001 RSNA scientific assembly. Received May 24, 2001; revision requested June 25; revision received August 20; accepted September 28. Address correspondence to F.S.P. (e-mail: s-pereles@northwestern.edu).
Comprehensive aortic magnetic resonance (MR) examinations currently include multiple nonenhanced and contrast materialenhanced sequences. The authors hypothesized that the nonenhanced true fast imaging with steady-state precession (FISP) portion alone of their comprehensive imaging protocol would be adequate to confidently confirm or exclude dissection or aneurysm of the aorta. In a retrospective review of 29 comprehensive thoracic aortic MR examinations, nonenhanced true FISP MR imaging alone was 100% accurate for determining the presence or absence of dissection or aneurysm.
