The value of 16 detector spiral CT for the superior mesenteric artery dissection

Objective To explore application value of 16detecter spiral CT angiography for dissecting aneurysm of aorta.Methods Retrospectively analyzed 9cases of patients with the dissection of superior mesenteric artery in admission from January 2010 to December 2012,the cases were diagnosized by 16detecter spiral CT angiography for dissecting aneurysm of aorta.post-processing techniques such as maximum density projection,multi-plane reorganization and curved surface reconstruction and volume were used analyzed and diagnosized.Results These pathological changes such as superior mesenteric artery sandwich of true,false cavity and inner diaphragm,broken mouth position,sandwich cumulative range and whether merger thrombus,branch vascular involvement could be displayed by 16detector CT vascular imaging and post-processing technology.Conclusion 16layer detector CT imaging and post-processing techniques of blood vessels could clearly show the mesenteric artery sandwich,which might be play an important role for timely and accurate diagnosis.
