目的:探讨螺旋CT双期增强扫描与胃镜检查对胃癌诊断的价值。方法:对60例经手术及病理检查证实为胃癌的患者分别行螺旋CT双期增强扫描和电子胃镜检查,比较二者在判断早期胃癌、进展期胃癌及术前分期方面的差异。结果:胃镜在早期胃癌的诊断方面优于螺旋CT双期增强扫描,对于进展期胃癌的诊断价值两者相近,判断术前分期CT有较大优势。结论:螺旋CT双期增强扫描与电子胃镜对胃癌的诊断各具优劣,只有两者相互结合,相辅相成,才能完善胃癌病变的检查。
Objective: To investigate the value of dual-phase helical CT scanning and gastroscopy in the diagnosis of gastric cancer. Methods: Sixty patients with gastric cancer confirmed by operation and pathology were examined by spiral CT dual-phase contrast-enhanced scanning and electron gastroscopy respectively. The differences between the two methods in determining early gastric cancer, advanced gastric cancer and preoperative staging were compared. Results: Gastroscopy was superior to double-helical CT in the diagnosis of early gastric cancer, and the diagnostic value of the gastroscope was similar to that of the advanced gastric cancer. It is of great advantage to judge preoperative staging CT. Conclusion: Spiral CT double-phase enhanced scanning and electronic gastroscopy for the diagnosis of gastric cancer have their own advantages and disadvantages, only the two combined with each other, complement each other in order to improve the examination of gastric lesions.
