目的 探讨多层螺旋CT(MSCT) 多平面重建技术在胃癌诊治中的应用价 值。方法 回顾性分析2013年3月-2015 年1月我院经手术病理确诊的60例胃癌 患者为研究对象，受试患者均行MSCT平 扫及多平面重建技术扫描，并与术后病 理检查结果进行对比分析。结果 胃癌 MSCT诊断的影像学表现(病灶部位、大 小、形态、邻近结构、远处转移)具有典 型特征；MSCT多平面重建技术对胃癌早 期、进展期准确检出率与病理检查结果 相较无明显差异(P＞0.05)；胃癌T分期 的MSCT诊断与病理检查结果符合率分别 为T1期(75.00%)、T2期(66.67%)、T3期 (86.67%)、T4期(81.82%)。结论 MSCT多 平面重建技术在胃癌诊治中有较高检出 率，对患者术前T分期诊断与病理检查结 果符合率高，对胃癌患者术前评估及合 理手术方案的制定提供重要参考。

Objective To explore the value of multi-slice spiral CT (MSCT) multiplanar reconstruction technique in the diagnosis and treatment of gastric cancer. Methods Sixty patients with pathologically confirmedgastric cancer who were admitted to the hospital between March 2013 and January 2015 were selected as study subjects. All patients underwent MSCT scan and multiplanar reconstruction scanning, and the results were compared with the results of pathological examination. Results The imaging findings of MSCT in the diagnosis of gastric cancer (location, size, shape, adjacent structures and distant metastasis of lesions) were typical.The accurate detection rates showed no significant difference between MSCT multiplanar reconstruction technique and results of pathological examination in early and advanced gastric cancer (P>0.05). The coincidence rates of MSCT diagnosis and pathological examination in T stagingof gastric cancer were T1 (75.00%), T2 (66.67%), T3 (86.67%) and T4 (81.82%). Conclusion The detection rate of MSCT multiplanar reconstruction technique is high in gastric cancer, and the coincidence rate with results of pathological examination is highin the diagnosis preoperative T staging, which provides important reference for preoperative evaluation and development of reasonable operation plan.
