Abstract:
Objective To evaluate the diagnostic value of MSCT angiography and postprocessing techniques in the diagnosis of spontaneous isolated dissection of superior mesenteric artery(SIDSMA).Methods Twenty patients with SIDSMA performed with MSCT angiography were analyzed retrospectively.The volume data were transferred to the workstation for image postprocessing and performed with various postprocessing techniques such as multi-planar reconstruction(MPR),curved planar reconstruction(CPR), volume rendering(VR)and maximum intensity projection(MIP).Results The dissection length of SIDSMA was positively correlated with visual analogue scale(VAS).MPR,CPR and VR clearly showed the intimal flap,true and false lumen.MPR and CPR displayed more entries of dissection than VR.VR demonstrated the extension of the involved aorta and its branches,but cannot satisfactorily demonstrate the entry of SIDSMA.Conclusion MSCT angiography is of positive applicable value to the diagnosis of SIDSMA.MPR, CPR and VR may be optimal choice as post processing techniques for diagnosis of SIDSMA.
