Figure 8a.   Aortoannular ectasia in a patient with Marfan disease. (a) Oblique MIP image clearly shows aortoannular ectasia (arrow). The entire thoracic aorta was imaged in a single breath hold, thus eliminating the need for acquisition of multiple breath-hold cine or spin-echo sections. (b) Coronal 3D partition shows a focal area of signal void due to aortic insufficiency (arrow).
