目的:分析多层螺旋CT在进展期胃癌术前分型和T分期中的应用价值。方法:选择我院2012年1月至2105年1月收治的经手术病理证实的进展期胃癌患者40例,术前1周对患者进行64排螺旋CT平扫和静脉期、动脉期双期增强扫描,给予多平面重组图像后处理,将扫描结果和术后病理结果进行对照分析。结果:多层螺旋CT双期增强检查联合多平面重组图像后处理技术,对进展期胃癌的检出率为100%,胃癌术前多层螺旋CT大体分型和T分期的总体准确率分别为85.0%和80.0%。结论:多层螺旋CT双期增强检查联合多平面重组技术,对进展性胃癌患者的术前分型和T分期具有较高的准确率,应该当成胃癌患者的术前常规检查内容。
Objective: To analyze the value of multislice spiral CT in the preoperative classification and T staging of advanced gastric cancer. Methods: Forty patients with advanced gastric cancer confirmed by surgery and pathology admitted to our hospital from January 2012 to January 2105 were selected. One week before operation, the patients underwent 64-slice spiral CT scan and venous phase, while the arterial phase was enhanced Scan, given multi-plane image reconstruction after the treatment, the scan results and postoperative pathological results were analyzed. Results: The detection rate of multi-slice helical CT double-phase enhanced imaging combined with multi-plane image reconstruction was 100% for advanced gastric cancer. The gross classification and T-staging accuracy of preoperative multi-slice spiral CT in gastric cancer were 85.0% and 80.0%. Conclusion: The double-phase multi-slice spiral CT combined with multiplanar reconstruction has a high accuracy in preoperative classification and T staging of patients with advanced gastric cancer and should be regarded as routine preoperative examination in patients with gastric cancer.
