目的 与上消化道钡餐、胃镜及手术标本对照评价螺旋CT成像技术对胃良恶性溃疡的诊断价值。方法 经手术病理证实 5 8例胃良恶性溃疡行胃产气后螺旋CT检查 ,其中 49例行上消化道钡餐检查 ,3 9例有手术标本和胃镜录像。由 2位放射科医师对SCT及UGI图像分别进行盲法阅读 ,评价病变的探测力 ,定性及诊断可信度分析 ,阅片者间的一致度采用K检验。结果 5 8例溃疡病灶经FG和手术病理共检出 72个病灶 ,SCT检出 69个 ,UGI检出 2 3个病灶 (P <0 .0 5 )。良恶性溃疡的定性SCT及UGI与手术病理对照无明显差异 ,结论 SCT对胃部良恶性溃疡定位定性与UGI相仿 ,但对病灶的探测率CTVG和轴位高于SSD和Raysum ,更高于上消化道钡餐。
Objective To evaluate the diagnostic value of spiral CT imaging in the diagnosis of benign and malignant gastric ulcer by the comparison of barium meal, gastroscopy and surgical specimens of upper gastrointestinal tract. Methods Fifty-eight cases of gastric benign and malignant gastric ulcer were confirmed by operation and pathology. Gastroscopy was performed after spiral CT, including 49 cases of upper gastrointestinal barium meal examination and 39 cases of surgical specimens and gastroscopy. Two radiologists carried out blinded readings on SCT and UGI images, respectively, to evaluate the probing power, qualitative and diagnostic credibility of the lesions, and the K-test was used to determine the concordance among readers. Results A total of 72 lesions were detected in 58 cases of ulcer lesions by FG and surgical pathology, 69 were detected by SCT, and 23 lesions were detected by UGI (P <0.05). Qualitative and benign and malignant ulcer SCT and UGI and surgical pathology control no significant difference, Conclusion SCT localization of benign and malignant gastric ulcer qualitative and UGI similar, but the detection rate of lesions CTVG and axis higher than the SSD and Raysum, higher than the Gastrointestinal barium meal.
