探究放射线和CT对肺段隔离症的临床诊断价值

Investigation on the clinical value of radiation and CT in the diagnosis of pulmonary sequestration

目的探究放射线和电子计算机断层扫描(CT)对肺段隔离症的临床诊断价值。方法选取60例肺段隔离症患者作为研究对象,均行放射线和CT检查。比较两种检查方法对肺段隔离症的诊断准确率,并详细探究肺部病灶的CT影像学特征。结果60例患者经手术病理检出实性病灶14例、囊性病灶24例、囊实性病灶22例。放射线对实性病灶、囊性病灶、囊实性病灶的诊断准确率分别为57.1%(8/14)、91.7%(22/24)、81.8%(18/22),CT对实性病灶、囊性病灶、囊实性病灶的诊断准确率分别为92.9%(13/14)、91.7%(22/24)、95.5%(21/22),CT的诊断总准确率93.3%(56/60)高于放射线的80.0%(48/60),差异具有统计学意义(P<0.05)。全部患者肺内肿块均呈异常密度,有20例圆形分布在左肺下叶后位置,8例块状出现在右肺上右支气管旁,10例三角区密度分布不均,7例右上肺片存在高密度影且不均匀,8例在右肺下出现叶外病灶,6例病灶出现在右肺门周边,8例严重感染者,空洞厚壁明显在右下肺。结论在肺段隔离症的临床诊断中,CT检查的准确率高于放射线,有效呈现肺部病灶的影像学特征,为预后治疗提供科学及准确的数据作为影像参考,值得在临床检查诊断中推广与应用。

Objective To investigate the clinical value of radiation and computed tomography(CT)in the diagnosis of pulmonary sequestration.Methods 60 patients with pulmonary sequestration were selected for the study,all of whom underwent radiation and CT examinations.The diagnostic accuracy of the two examination methods for pulmonary sequestration was compared,and the CT imaging characteristics of pulmonary lesions were explored in detail.Results 60 patients were found to have solid lesions in 14 cases,cystic lesions in 24 cases,and cystic solid lesions in 22 cases by surgical pathology.The diagnostic accuracy of radiation for solid lesions,cystic lesions,and cystic solid lesions were 57.1%(8/14),91.7%(22/24),and 81.8%(18/22),respectively.The diagnostic accuracy of CT for solid lesions,cystic lesions,and cystic solid lesions were 92.9%(13/14),91.7%(22/24),and 95.5%(21/22),respectively.The overall diagnostic accuracy 93.3%(56/60)of CT was higher than 80.0%(48/60)of radiation,and the difference was statistically significant(P<0.05).All patients had abnormal density of intrapulmonary masses,with 20 cases of circular distribution in the posterior position of the left lower lobe,8 cases of mass appeared near the right upper and right bronchus,10 cases of uneven distribution of triangular area,7 cases of high-density shadow and heterogeneity in the right upper lung lamina,8 cases of extralobar lesions in the lower right lung,6 cases of lesions appearing around the right hilum,and 8 cases of severe infection with cavernous thick walls evident in the right lower lung.Conclusion In the clinical diagnosis of pulmonary sequestration,the accuracy of CT examination is higher than that of radiation,and it can effectively present the imaging characteristics of lung lesions and provide scientific and accurate data as an imaging reference for prognosis and treatment,which is worth promoting and applying in the clinical examination and diagnosis.
