摘　　要：目的探究肺部转移瘤的发生情况,并对多层螺旋CT的诊断价值进行分析。方法选取70例在2015年1月—2018年11月该院收治的肺部转移瘤患者,对所有患者的临床病历资料进行回顾性分析,对多层螺旋CT检查中病灶的内部结构、形态及边缘等影像特征进行综合分析,同时按照病理结果,对多层螺旋CT的诊断效能进行有效评估。结果通过病理结果证实,70例患者中有67例为肺部转移瘤,有3例良性病灶;原发灶的类型主要包括乳腺恶性肿瘤、呼吸系统恶性肿瘤、消化系统恶性肿瘤及其他类型,分别包含14例(20.90%)、15例(22.39%)、35例(52.24%)及3例(4.48%);转移类型主要包括单发转移型、多发转移型及弥漫转移型,分别包含9例(13.43%)、37例(55.22%)及21例(31.34%);在多层螺旋CT检查期间,主要出现钙化、晕征、毛刺征、分叶征及支气管征象;与多层螺旋CT平扫相比,多层螺旋增强扫描在肺部转移瘤诊断过程中存在较高的诊断准确率(92.54%),多层螺旋CT平均准确率较低(77.61%),差异有统计学意义(χ2=13.023,P<0.05)。结论肺部转移瘤这一恶性肿瘤主要在呼吸系统和消化系统中发生,同时主要为多发转移,通过多层螺旋CT检查具有相关的影像特征,特别是多层螺旋CT增强扫描,其诊断效能较高,能够有效提高诊断准确率,因此在临床医学治疗期间,它可以将可靠的参考依据提供。Objective To investigate the occurrence of pulmonary metastases and analyze the diagnostic value of multi-slice spiral CT.Methods A total of 70 patients with pulmonary metastases admitted to the hospital from January 2015 to November 2018 were selected.The clinical data of all patients were retrospectively analyzed,and the internal structure and morphology of the lesions were examined by multi-slice spiral CT.Comprehensive analysis of imaging features such as the edge and the edge,and the effective evaluation of the diagnostic efficacy of multi-slice spiral CT according to the pathological results.Results It was confirmed by pathological results that 67 of the 70 patients were metastatic lung tumors and 3 were benign lesions.The types of primary lesions mainly include breast malignant tumors,respiratory malignant tumors,digestive system malignant tumors,and other types.They included 14 cases(20.90%),15 cases(22.39%),35 cases(52.24%),and 3 cases(4.48%).The types of metastasis mainly included single metastasis,multiple metastases,and diffuse metastases,each including 9 cases(13.43%),37(55.22%),and 21(31.34%);during the multi-slice spiral CT examination,calcification,halo sign,glitch sign,lobular sign,and bronchial signs mainly appeared;and multi-slice spiral compared with plain CT scans,multi-slice spiral enhanced scans have higher diagnostic accuracy(92.54%)in the diagnosis of lung metastases,multi-slice spiral CT scan accuracy in low(77.61%),the difference was statistically significant(χ2=13.023,P<0.05).Conclusion Malignant tumor of the lung mainly occurs in the respiratory system and the digestive system,and it is mainly multiple metastases.Multi-slice spiral CT examination has relevant imaging features,especially multi-slice spiral CT enhanced scanning,and its diagnostic efficacy Higher,it can effectively improve the diagnostic accuracy,so it can provide reliable references during clinical medical treatment.
