ABSTRACT

Objective To investigate the accuracy of CT in the diagnosis of central lung cancer and the clinical significance of magnetic resonance imaging ( MRI) supplementary diagnosis ,in order to provide reference for clinical diagnosis.Methods From January 2015 to October 2017,30 patients with suspected central lung cancer treated in General Hospital of Lingchuan County Medical Group were selected in the research .All patients were examined by CT and MRI ,and the results of pathological examination were taken as the standard .The results of CT and MRI were observed and the value of MRI supplementary examination in CT diagnosis was analyzed .Results The sensitivity,specificity and accuracy of CT in the diagnosis of central lung cancer were 68.0％,20.0％and 60.0％, respectively .After MRI imaging supplementary diagnosis , the diagnostic sensitivity , specificity and accuracy of diagnosis of central lung cancer were 92.0％,80.0％ and 90.0％, respectively.Conclusion The accuracy of diagnosis of central lung cancer by CT is low .In order to ensure the accuracy of diagnosis ,it is necessary to carry out MRI supplementary diagnosis to the patients .
