Title: Comparison of different post-processes of dual-source CT in diagnosis of superior mesenteric artery stenosis
Abstract: Objective To observe the value of the post-processes of dual-source CT in the diagnosis of superior mesenteric artery(SMA) stenosis.Methods Twelve patients with SMA stenosis confirmed with digital subtraction angiography(DSA) and operation were enrolled.CT angiograms were reconstructed with multiplanar reconstruction(MPR),maximum intensity projection(MIP) and volume rendering(VR).With the Results of DSA and operation as golden standard,the sensitivity and the specificity of different CT post-processes in the diagnosis of SMA stenosis were compared.Results The MPR,MIP and VR had sensitivity of 75.00%,62.50% and 43.75%,specificity of 98.00%,92.22% and 89.29%,respectively.There was no statistical difference between MPR and MIP in diagnosing SMA stenosis(P0.05),but statistical difference was found between MPR and VR(P0.05).Conclusion Each post-processing technology has its own advantage.Integration of them helps to accurate diagnosis of SMA stenosis.
