MSCT对肺转移瘤的诊断价值

Diagnostic value of MSCT in pulmonary metastasis tumor

目的探讨肺转移瘤的发生情况及多层螺旋计算机断层扫描(MSCT)对其诊断价值。方法选取2015年1月至2020年6月我院150例疑似肺转移瘤患者作为研究对象,均行X线及MSCT检查。以穿刺活检病理诊断为金标准,比较X线、MSCT对肺转移瘤的诊断效能。比较X线、MSCT对不同类型、不同临床分期肺转移瘤的诊断符合率。分析X线、MSCT诊断结果与穿刺活检病理诊断结果的一致性。结果以穿刺活检病理诊断为金标准,MSCT对肺转移瘤的诊断灵敏度、特异度、准确度、阳性预测值、阴性预测值均高于X线(P<0.05)。MSCT对多发转移型、弥漫转移型肺转移瘤的诊断符合率均高于X线(P<0.05)。MSCT对Ⅰ、Ⅱ期肺转移瘤的诊断符合率均高于X线(P<0.05)。X线诊断结果与穿刺活检病理诊断结果间呈中度一致(Kappa值=0.635),MSCT诊断结果与穿刺活检病理诊断结果间呈高度一致(Kappa值=0.938)。结论肺转移瘤的原发癌灶主要为乳腺癌、结直肠癌,相较于X线,MSCT不仅对肺转移瘤具有较高的诊断价值,而且可对其类型、临床分期进行鉴别诊断。

Objective To investigate the occurrence of pulmonary metastasis tumor and the diagnostic value of multislice spiral computed tomography(MSCT)in this.Methods A total of 150 patients with suspected pulmonary metastasis tumors in our hospital from January 2015 to June 2020 were selected as the research objects,and all underwent X-ray and MSCT examination.Taking the pathological diagnosis of puncture biopsy as the gold standard,the diagnostic efficacy of X-ray and MSCT in pulmonary metastasis tumor was compared.The diagnostic coincidence rates of X-ray and MSCT in pulmonary metastasis tumor of different types and clinical stages were compared.The consistency between X-ray,MSCT diagnostic results and pathological diagnosis of puncture biopsy results were analyzed.Results Taking the pathological diagnosis of puncture biopsy as the gold standard,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value of MSCT in the diagnosis of pulmonary metastasis tumor were higher than those of X-ray(P<0.05).The coincidence rates of MSCT in the diagnosis of pulmonary metastasis tumors of multiple metastatic type and diffuse metastatic type were higher than those of X-ray(P<0.05).The coincidence rates of MSCT in the diagnosis of stageⅠandⅡpulmonary metastasis tumors were higher than those of X-ray(P<0.05).The X-ray diagnosis results were moderately consistent with the pathological diagnosis of puncture biopsy results(Kappa value=0.635),and the MSCT diagnosis results were highly consistent with the pathological diagnosis of puncture biopsy results(Kappa value=0.938).Conclusion The primary foci of pulmonary metastasis tumor is mainly breast cancer and colorectal cancer.Compared with X-ray,MSCT not only has higher diagnostic value for pulmonary metastasis tumor,but also can be used for differential diagnosis of its type and clinical stage.
