[The MRI diagnosis of aortic dissection].
OBJECTIVE
To analyze and address the MRI manifestations and diagnostic importance of aortic dissection.


METHODS
The MRI manifestations in 31 cases of aortic dissection were analyzed retrospectively. Sixteen cases were proved by operation and pathology.


RESULTS
MRI depicted an intimal flap and a double lumen in all 31 patients. The site of intimal tear was located in 7 cases. Also demonstrated were the complications: aortic dilation in 15 cases, aortic branches involvement in 5, thrombus formation in the false lumen in 5, aortic regurgitation in 10, left ventricle hypertrophy in 10, and leak into thorax in 2.


CONCLUSIONS
As a non-invading imaging method, MRI can demonstrate the site, range and complications of aortic dissection; it is very valuable in the diagnosis of aortic dissection.
