Abstract:
Objective To evaluate the value of multi-slice spiral CT (MSCT) angiography in diagnosis of thoracic vascularemergency.Methods 25 cases suspected of thoracic vascular emergency were examined with MSCT. Two dimensional and three dimensionalimaging methods were used. Results Central pulmonary embolism 10 cases, aortic dissection 12 cases,aneurysm 2 cases and takayasuarteritis with stricture of kidney artery were found by two dimensional imaging(MPVR,CPR),and the extent, size and details of lesions couldbe showed well. The space relationship and calcifation of aorta were displayed in three dimensional imaging(SSD,VR,MIP). Therelationship between intraluminal embolism and the wall of pulmonary artery, as well as intimal flap and reentry of dissection could bevealuated by CTVE.Conclusion Associated with imaging post processing,MSCT angiography is an effective method in diagnosis of thoracic vascular emergency.
