Objective To investigate 64 row helical CT multiphase scanning and image post -processing technique in the stomach,intestinal lesions of diagnostic value.Methods 216 cases of collecting our hospital stomach,intestinal disease patients,and the abdominal plain and enhanced scanning,image post-processing worksta-tion to scan data of 3-d reconstruction.Results 216 cases of clinical suspected stomach,intestinal disease in 65 patients with gastric cancer,gastric stromal tumor 22 ca-ses,12 cases of gastric ulcer,gastric fundal varices 47 cases of gastric polyps,10 cases of small intestinal stromal tumor,12 cases of small intestinal lymphoma,eighteen cases,duodenal diverticulum 30 cases of doctor of vice director of by two independent read a slice,compared with pathology results,retrospective summary lesions CT per-formance.Diagnosis and fibre endoscope and/or surgery can see contrast analysis,only 5 cases of gastric ulcer cannot be decided its benign and malignancy,8 cases of duodenal diverticulum reduction,6%of all cases,diagnosis coincidence rate is 96%.Conclusion Using 64 row helical CT scanning period and a variety of image recon-struction mode can through all show stomach,small gut cavity inside and outside lesions,we can find small lesions,and found that the transfer of around,for clinical pro-vide more valuable information.
