摘　　要：目的探讨MSCT胃低张充气成像技术对胃癌进行术前分期诊断的临床应用价值。方法前瞻性的对临床诊断为胃癌的69例患者进行胃低张充气成像及MSCT动态增强扫描,搜集经手术、病理证实的21例进行胃低张充气成像患者的手术及病理资料,对照分析术前CT分期与手术、病理分期的相关性。结果胃低张充气成像法的T分期准确率为80.9%,N分期准确率为52.4%;回顾性随机抽取20例胃癌患者进行传统水充盈法CT资料及手术病理资料,双盲法对其进行术前CT TNM分期,对照其手术病理分期,结果显示胃水充盈法的T分期准确率为66.7%,N分期准确率为50.8%。对比上述结果显示胃低张充气成像法T分期准确率明显高于传统水充盈法,N分期准确率无显著提高。结论 MSCT胃低张充气成像技术对胃癌进行术前分期诊断中T分期准确率高于传统水充盈法。Objective To investigate the clinical value of hypotonic air-distended MSCT imaging in the evaluation of preoperative staging diagnosis for gastric cancer.Methods Prospectively studied 69 cases gastric cancer confirmed by clinical diagnosis,these patients were undergone hypotonic air-distended and dynamic contrast-enhanced MSCT scanning before operation.Collected the clinical and pathological dates of 21 cases confirmed by operation,To Analysis the correlation of CT preoperative stage and pathological stage.Results The T staging of hypotonic air-distended MSCT imaging was 80.9%,the N staging was 52.4%.Retrospectively studied the dates of 20 cases by waterdistended MSCT imaging,The T staging of water-distended MSCT imaging was 66.7%,the N staging was 50.8%.The results showed preoperative T staging accuracy rate for gastric cancer by hypotonic air-distended MSCT imaging better than water-distended MSCT imaging,but the preoperative N staging accuracy rate didn't improve significantly.Conclusion The preoperative T staging accuracy rate for gastric cancer by hypotonic airdistended MSCT imaging was better than water-distended MSCT imaging.
