Abstract
Objective To explore the application value of multi-slice spiral CT(MSCT)examination in the differential diagnosis of benign and malignant pulmonary ground glass nodules(GGN).Methods 100 patients with GGN were examined by MSCT.With the pathological diagnosis results as the gold standard,the efficiency of MSCT in diagnosing GGN was calculated,and the MSCT parameter characteristics were compared between benign and malignant GGN patients.Results Among 100 patients with GGN,67 were malignant and 33 were benign.MSCT examination showed 63 cases of malignancy and 37 cases of benign;The sensitivity,specificity,and accuracy of MSCT in diagnosing GGN were 92.54%,96.97%,and 94.00%,respectively,with excellent consistency with pathological results(Kappa=0.868,P<0.001).The lesion diameter,plain CT value,and enhanced CT value of GGN patients with malignant lesions were greater than those of GGN patients with benign lesions,and the detection rates of mGGN,irregular shape,blurred boundary,spiciness,lobulation,vascular bundle sign,pleural indentation sign,bronchial inflation sign,and vacuolar sign were higher than those in GGN patients with benign lesions(P<0.05).Conclusions MSCT examination has high efficiency in distinguishing benign and malignant GGN,and observing the MSCT parameter characteristics can provide a basis for the differential diagnosis of benign and malignant GGN.关键词
