Abstract: ObjectiveTo estimate the value of CT virtual colonoscopy (CTVC) and its image postprocessing techniques in the diagnosis of colorectal diseases.MethodsCTVC images of 84 patients with suspected colorectal diseases were retrospectively analyzed combined with multiple planar reconstruction (MPR),shaded surface display(SSD) and transparent image reconstruction.The location,size,shape and type of the lesions were analyzed and the images were compared with electronic colonoscopy and pathologic specimen finding.ResulltsFify-nine of 84 patients were diagnosed as coloretal cancer (23 cases with cancer in sigmoid colon,22 cases in rectum,11 cases in ascending colon and 3 cases in appendix),8 cases were porctopolypus,3 cases were multiple colonic diverticula,1 case was hemorrhoids,13 cases were normal.All the diagnosis was confirmed correct by operation pathology or clinic.ConclusionCTVC can show the shape and other features of colorectal diseases,and has important significance for clinical staging and surgical planning of colorectal cancer.
