摘要
目的 分析能谱CT影像组学对胃癌患者术前病理分级的诊断价值.方法 80 例胃癌患者入院后均行常规CT平扫与能谱CT增强扫描,比较二者的检查结果以及诊断价值.结果 80 例胃癌患者经手术病理检查明确低分化者 53 例,高分化者27 例.Kappa检验显示,CT平扫与手术病理的术前病理分级结果具有一般的一致性(Kappa值 = 0.677,P＜0.05),而能谱CT与手术病理具有较高的一致性(Kappa值= 0.911,P＜0.05).能谱CT诊断胃癌患者术前病理分级的灵敏度、特异度与准确度均高于CT平扫(P＜0.05).结论 与CT平扫相比,能谱CT在胃癌患者术前病理分级诊断中的准确性更高.
Abstract
Objective To analyze the diagnostic value of spectral CT radiomics in preoperative pathological grading of patients with gastric cancer.Methods 80 patients with gastric cancer underwent routine CT plain scan and spectral CT enhanced scan after admission,and the results and diagnostic value of the two were compared.Results Of the 80 patients with gastric cancer,surgical pathological examination showed 53 cases of low differentiation and 27 cases of high differentiation.Kappatest showed that the preoperative pathological grading results of CT plain scan and surgical pathology had general consistency(Kappavalue = 0.677,P<0.05),while spectral CT had high consistency with surgical pathology(Kappavalue = 0.911,P<0.05).The sensitivity,specificity and accuracy of spectral CT in the diagnosis of preoperative pathological grading of gastric cancer patients were higher than those of CT plain scan(P<0.05).Conclusions Compared with CT plain scan,spectral CT has higher accuracy in the diagnosis of preoperative pathological grading of patients with gastric cancer.
