Abstract:
Objective To assess feasibility of three-dimensional(3D) reconstruction techniques and virtual gastroscopy of CT(CTVG)in diagnosing gastric tumors.Methods 22 cases doubted with gastric lesions were scaned by mutislice helic CT and reconstructed into CTVG and 3D images.The results were compared with fiberoptic gastroscopy(FG) and all of the cases were sure with gastric lesions and biopsied by gastroscopy or surgery operation.Results 22 patients was examinated successfully,and the lesions was proved by pathology of FG or operation.According to location and shape of lesions,there were more ulcer type(16) and more located at gastric antrum(14) in this specimen.Both CTVG and FG had one misdiagnosis respectively.Conclusion CTVG combined with 3D of MSCT is same sensitivity and specificity as FG.
