X线联合CT检查在早期肺部感染中的诊断价值

The diagnostic value of X-ray combined with CT in early pulmonary infection

目的评价分析应用X线联合CT检查诊断早期肺部感染的临床价值,为临床诊断提供更可靠的依据,以减少漏诊、误诊问题。方法选取62例在2020年3月—2021年3月高唐县人民医院收治的早期肺部感染患者为本次研究对象,先后接受X线检查、CT检查,以痰液培养结果为金标准,比较X线检查与X线联合CT检查两项结果的灵敏度、特异度、准确性,分析不同类型肺部感染者影像学特征,探究不同检查的临床诊断价值。结果X线检查的灵敏度为38.89%、特异性为56.82%、准确率为51.61%;X线联合CT检查的灵敏度为88.89%、特异性为95.35%、准确率为91.94%,差异有统计学意义(P<0.05)。且不同类型肺部感染者影像学特征也存在明显差异。结论与单纯的接受X线检查相比,X线检查联合CT检查能够更灵敏、准确地诊断早期肺部感染疾病,且能够更清晰地了解肺部感染的具体情况,如有无磨玻璃影、结节影等,为临床诊断提供直观、可靠的依据,以减少漏诊、误诊问题,建议可作为早期肺部感染疾病的主要检查形式。

Objective To evaluate and analyze the clinical value of X-ray combined with CT in the diagnosis of early pulmonary infection,so as to provide a more reliable basis for clinical diagnosis,and to reduce the problem of missed diagnosis and misdiagnosis.Methods From March 2020 to March 2021,62patients with early pulmonary infection treated in Gaotang County People’s Hospital were selected as the subjects of this study,and were successively examined by X-ray and CT.The sputum culture results were taken as gold standard,so as to compare the sensitivity,specificity and accuracy of X-ray examination and X-ray combined with CT examination,analyze the imaging characteristics of different types of pulmonary infection,and explore the clinical diagnostic value of different examinations.Results The sensitivity,specificity and accuracy of X-ray examination were 38.89%,56.82%and 51.61%,respectively;and the sensitivity,specificity and accuracy of X-ray combined with CT were 88.89%,95.35%,and 91.94%,respectively;and the differences were statistically significant(P<0.05).The imaging characteristics of different types of pulmonary infection were also significantly different.Conclusion Compared with simple X-ray examination,X-ray examination combined with CT examination could be more sensitive and accurate in diagnosis of early pulmonary infection diseases,and more clearly understand the specific situation of pulmonary infection,such as whether there was ground glass shadow or nodule shadow,in order to provide an intuitive and reliable basis for clinical diagnosis,so as to reduce missed diagnosis and misdiagnosis.It was suggested to be used as the main examination form of early pulmonary infection diseases.
