조기 위암진단 있어 수술 전 64volume CT를 이용한 가상위내시경과 수술 후 병리조직결과의 비교

Preoperative early gastric cancer staging diagnosis by virtual gastroscopy using 64 volume CT : comparison of histopathologic result

Purpose The arm of this study was prospectively evaluate the accuracy of multi- detector row computed tomography(CT) virtual gastroscopy(VG) and multi-planar reconstruction(MPR) image for detection, precise localization and staging of gastric cancer by comparison with conventional endoscopy and histopathology. Materials and Methods This study shows EGC which is in the Endoscopy from January 2006 to January 2007 and then we analyze who is confirmed 83 patients by histopathology of operative. Prior to evaluated virtual EndC6copy opinion which is 64Volume CT before operative. We gain the images which is used by contrast 140ml and for expansion stomach by air and then injected contrast after 70sec. We obtained images which is workstation by Vutual Gastroscopy and multi-planar reconstruction Results We can’t detected region only 15examples(18%) that EGC 83 examples are standard hsiopathology using a VG and MPR in 64Volume CT. EGC are located where are antrum(38%), Body(30%), Lesser Curvature & Great Curvature(32%), generally region detected antrum, the distinction of sex Man 61patients(73%) and Women 22 patients(32%). Conclusion use of the combination of virtual gastroscopy and dynamic contrast-enhanced MPR images obtained at 64channel volume CT after air and water distention of the stomach can safe methods and useful but which is need endoscopy so compliment with Volume CT.
