摘要【目的】探讨多层螺旋CT(MSCT)动态增强扫描联合三维成像技术对胃癌的诊断价值。【方法】96例经胃镜病理检查证实的胃癌患者,其中进展期胃癌80例,早期胃癌16例,患者均行MSCT与三维成像技术检查。比较进展期和早期胃癌患者的MSCT扫描和三维成像技术扫描表现及与病理诊断结果的差异。【结果】MSCT扫描结果显示:80例进展期胃癌患者中有71例胃壁增厚、病灶的异常强化、胃腔狭窄、病灶表面可见不规则凹陷、环形隆起,9例病灶强化不明显。16例早期胃癌患者中有14例动脉期检出病灶,2例未出现强化。三维成像技术扫描结果显示,80例进展期胃癌患者管腔狭窄更直观,增强后病灶中等至明显强化;16例早期胃癌患者中10例动脉期检出病灶,呈不均匀强化,慢进慢出型模式,6例未出现明显强化。MSCT诊断中,进展期胃癌患者与病理诊断符合率为71.25%(57/80),早期胃癌患者与病理诊断符合率为50.00%(8/16),总符合率为67.71%(65/96)。三维成像技术诊断中,进展期胃癌患者与病理诊断符合率为88.75%(71/80),早期胃癌患者与病理诊断符合率为56.25%(9/16),总符合率为83.33%(80/96)。MSCT联合三维成像技术诊断与病理诊断结果相符,联合诊断准确率为96.88%(93/96),高于单独诊断(P<0.05)。【结论】MSCT、三维成像技术均可用于进展期胃癌与早期胃癌患者的鉴别诊断,二者联合诊断效果更佳。

Abstract：【Objective】To explore the diagnostic value of dynamic contrast-enhanced multi-slice spiral CT (MSCT) combined with three-dimensional imaging technology for gastric cancer. 【Methods】A total of 96 gastric cancer patients confirmed by gastroscopy pathology, including 80 cases of advanced gastric cancer and 16 cases of early gastric cancer.All patients underwent MSCT and three-dimensional imaging techniques. We compared the MSCT and three-dimensional imaging findings of patients with advanced and early gastric cancer with pathological diagnosis. 【Results】The MSCT scan results showed that 71 out of 80 patients with advanced gastric cancer had thickening of the gastric wall, abnormal enhancement of the lesion, narrowing of the gastric cavity, irregular depressions and circular protrusions visible on the surface of the lesion, and 9 cases had no obvious enhancement of the lesion. Among 16 early gastric cancer patients, 14 lesions were detected in the arterial phase, and 2 did not show enhancement. The scanning results of three-dimensional imaging technology showed that the lumen stenosis of 80 patients with advanced gastric cancer was more intuitive, and the lesions were moderately to significantly enhanced after enhancement; Among the 16 early gastric cancer patients, 10 lesions were detected in the arterial phase, showing uneven enhancement and a slow in slow out pattern, while 6 cases did not show significant enhancement. In MSCT diagnosis, the coincidence rate between advanced gastric cancer patients and pathological diagnosis was 71.25%(57/80), and the coincidence rate between early gastric cancer patients and pathological diagnosis was 50.00%(8/16), with a total coincidence rate of 67.71%(65/96). In the diagnosis of three-dimensional imaging technology, the coincidence rate between advanced gastric cancer patients and pathological diagnosis was 88.75%(71/80), early gastric cancer patients and pathological diagnosis was 56.25%(9/16), and the total coincidence rate is 83.33%(80/96). The diagnosis of MSCT combined with three-dimensional imaging technology was consistent with the pathological diagnosis results, with a combined diagnostic accuracy of 96.88%(93/96), which was higher than that of individual diagnosis (P<0.05). 【Conclusion】MSCT and 3D imaging techniques can be used for the differential diagnosis of advanced gastric cancer and early gastric cancer patients, and the combination of the two has a better diagnostic effect.
