胃CT仿真内窥镜结合二维CT的临床应用

Clinical application of CT virtual gastroscopy combined with 2D CT

目的 评价胃CT仿真内窥镜 (CTVE)的临床应用价值。方法 对比分析经胃CTVE +二维CT、胃造影 (GI)、纤维胃镜 (FG)检查的 5 2例 6 5个胃部病灶 ,“四定”准确率。结果 胃CTVE发现 0 3cm隆起及凹陷性病灶及定量、定位、定性的准确率 :胃CTVE高于GI(P <0 0 0 1)、低于FG(P >0 0 5 ) ;定期准确率 :胃CTVE优于GI、FG。结论 胃CTVE作为FG的一种补充检查手段 ,在常见的胃器质性疾病方面可以取代GI。

Objective To evaluate the value of CT virtual gastroscopy (CTVE) in clinical applications. Methods 52 patients (65 foci of stomach) were examined by CTVE combined with 2D CT, gastrointestinal series (GI) and fibric gastroscopy (FG). The accurate ratio in quantitative, locating, qualitative and staging diagnoses was compared. Results\ CTVE demonstrated the diameter of 0 3 cm foci in stomach. The accurate ratio in quantitative, locating and qualitative diagnoses with combination of CT and CTVE was higher than that of GI ( P <0 001 ) but lower that of FG ( P >0 05); In staging, CTVE was better than GI and FG. Conclusion\ CTVE is a complementary gastric examination, which can replace GI in the diagnosis of common physical gastrical diseases.
