This pictorial essay illustrates the pre- and postoperative findings seen
in patients with aortic dissections on contrast-enhanced turbo- fast
low-angle shot (FLASH) MR images obtained in the plane of the aortic arch.
Contrast-enhanced images provide morphologic and functional information not
normally available with conventional spin- echo (SE) MR imaging or dynamic
CT. Preoperative examination of the acute dissection is often troubled by
cardiovascular insufficiency and motion artifacts. Therefore most of our
patients were examined postoperatively. The main reason for postsurgical
imaging is the evaluation of the flow in the different lumina and the
detection of complications (i.e., aneurysms or progress of dissection).
