Abstract:
Objective To evaluate spiral CT scanning and CT virtual endoscopy(CTVE) in the clinical diagnosis of gastric carcinoma.Methods Spiral CT scan was performed in 28 patients with pathologically-proved gastric cancer . The CT scan parameters were : collimating width 5 mm , Pitch 1 . The volumetric data were acquired using a spiral CT scanner and transferred to computer workstation . CTVE was performed by navigator smooth function . The results were compared with the findings of fiberoptic endoscopy and/or surgery .Results Spiral CT scan could demonstrate the location ,size,extension of lesions and the relation with organs around .In 28 patients,CT findings included omentum involvement(n=7),pancreatic ivolvement (n=4),hepatic involvement (n=3),lymph node metastasis(n=3). CTVE could clearly demonstrate the three-dimensional image of normal wall stomach and the lesions , size and extension of lesions . The appearances of the inner lesions and normal wall of stomach on CTVE were similar to those on fiberoptic endoscopy and/or surgery . The accuracy in detecting lesion by CTVE was 92.8% in 28 patients . Conclusion CTVE combination with spiral CT scan is of great value in clinical diagnosis of gastric carcinoma .
