摘要
目的 探究多层螺旋CT薄层扫描联合消化道造影诊断胃部肿瘤患者的临床价值。方法 收集2018年1月至2020年1月我院收治的62例胃部肿瘤患者的临床资料,所有患者均先后进行多层螺旋CT薄层扫描及消化道造影检查。检查结束后对所得图像进行分析,比较两种方法单独及联合诊断对胃壁增厚、软组织肿块、黏膜病变、恶性龛影的检出率及对胃部肿瘤T、N、M分期的诊断结果;并分析多层螺旋CT薄层扫描、消化道造影在胃部肿瘤T_(1)~T_(4)期的图像特征。结果 联合诊断对胃壁增厚、软组织肿块、黏膜病变、恶性龛影的检出率均高于多层螺旋CT薄层扫描及消化道造影(P<0.05)。联合诊断对T、M分期的诊断准确率高于多层螺旋CT薄层扫描、消化道造影,但差异无统计学意义(P>0.05);联合诊断对N分期的诊断准确率高于消化道造影(P<0.05)。多层螺旋CT薄层扫描、消化道造影在胃部肿瘤T_(1)~T_(4)期的图像特征:T_(1)期消化道造影显示肿瘤病变密度较均匀,多层螺旋CT薄层扫描图像显示胃壁向腔内凸出,浆膜外脂肪层清晰;T_(2)期消化道造影显示胃壁局限性增厚,多层螺旋CT薄层扫描图像显示胃壁局限性增厚,局部轮廓欠光整,浆膜外脂肪层较清晰;T_(3)期消化道造影出现深浅不同的分叶或多弧状切迹,多层螺旋CT薄层扫描图像显示浆膜外脂肪层模糊,胃壁增厚;T_(4)期消化道造影显示肿块黏膜表面出现恶性龛影,多层螺旋CT薄层扫描图像显示胃壁增厚,与胰尾部脂肪间隙消失。结论 多层螺旋CT薄层扫描与消化道造影在胃部肿瘤患者中有较高的诊断价值,但相较于单独应用一种诊断方法,联合诊断可提高患者的检出率,有利于进行术前TNM分期。
Objective To explore the clinical value of multi-slice spiral CT thin-slice scanning combined with gastrointestinal angiography in the diagnosis of patients with gastric tumors. Methods The clinical data of 62 patients with gastric tumors treated in our hospital from January 2018 to January 2020 were collected. All patients underwent multi-slice spiral CT thin-layer scanning and gastrointestinal angiography. The images was analyzed after the examination, and the detection rates of gastric wall thickening, soft tissue masses, mucosal lesions and malignant niches, and the diagnostic results of T, N and M stages of gastric tumors were compared between single and combined diagnosis of the two methods;the image features of multi-slice spiral CT thin-layer scanning and gastrointestinal angiography in T-Tstages of gastric tumors were analyzed. Results The detection rates of gastric wall thickening, soft tissue masses, mucosal lesions and malignant niches by combined diagnosis were higher than those by multi-slice spiral CT thin-layer scanning and gastrointestinal angiography(P<0.05);the diagnostic accuracy of combined diagnosis for T and M stages were higher than those of multi-slice spiral CT thin-layer scanning and gastrointestinal angiography, but the differences were not statistically significant(P >0.05);the diagnostic accuracy of combined diagnosis for N stage was higher than that of gastrointestinal angiography(P<0.05). Image characteristics of multi-slice spiral CT thin-layer scanning and gastrointestinal angiography in T-Tstages of gastric tumors: Tstage gastrointestinal angiography showed that the density of tumor lesions was relatively uniform, multi-slice spiral CT thin-layer scanning image showed that the gastric wall protruded into the cavity, and the extraserous fat layer was clear;Tstage gastrointestinal angiography showed gastric wall thickened locally, and multi-slice spiral CT thin-layer scanning image showed gastric wall thickened locally, local contour was not smooth, and the extraserous fat layer w
