title: [Techniques and clinical applications of 16 multislice helical CT in colonic diseases].
abstract: OBJECTIVE
  To evaluate the techniques and clinical applications of 16 multislice helical CT in colonic lesions.
  
  
  METHODS
  Eighty-one patients including 54 colorectal carcinomas, 5 adenomas, 1 non-Hodgkin's lymphoma, 6 inflammatory bowel diseases, and other 15 cases underwent volume scanning using 16 multislice helical CT. Four types of reconstruction included multiple planar reconstruction, shaded surface display, raysum, and CT virtual colonoscopy.
  
  
  RESULTS
  Complete colon could be shown in all patients. The lesions' morphology, number, size, location, intestinal cavity, pericolonic changes, and other abdominal organs were satisfactorily shown by CT.
  
  
  CONCLUSIONS
  Sixteen multislice helical CT colonography is a valuable imaging technique for detecting colonic diseases. It is effective in diagnosis and treatment planning. It can display the portions of colon that is inaccessible at colonoscopy.
