Abstract:
Objective To investigate the diagnostic Value of multi-slice spiral CT 3-Dimensional reconstruction in intestinal obstruction.Methods 28 Patients with malignant lesions of colon underwent volume scanning using multislice helical CT.Four types of reconstruction included multiple planner reconstruction(MPR),CT virtual colonoscopy(CTVC),shaded surface display(SSD)and raysum.The results were compared with those of colonoscopy and patholog.Results CT diagnostic accurate rate was 100%,and the accurate rate of the cause was 96% in intestinal obstruction,including primary or secondary neoplasms(18/28),abhesions(2/28),bowel torsion(2/28)and external or internal hernias(3/28) and gallstone ileus(3/28).Conclusion There were advantages and disadvantages in diagnosis of mechanical intestinal obstruction with MPR,CTVC,SSD and Raysum respectively.The combined use of the four post-processing technigues can be more helpful to precise localizing and qualitative diagnosis of lesions.MPR should be the optimal post-processing technigues for the diagnosis of intestinal obstruction
