Abstract:
Objective To evaluate the auxiliary diagnostic ability and applicability of the Lung Care software of dualsource CT in the study of solitary pulmonary nodule(SPN). Methods 40 cases with SPN proved by pathologically were examined by dual-source CT. R-MPR and VOI of Lung Care software three-dimension rebuilding image were obtained to analyze imaging features of SPN and compared with routine chest CT. 20 cases had regular visits during 12 months which were divided into three stages to measure the growing speed or doubling time. Results There were 28 cases of malignant nodules and 12 cases of benign nodules in 40 cases of SPN. The accuracy for malignancy of routine chest CT and LungCare software three-dimension rebuilding are 53.57% ,82.14% respectively. The accuracy for benign nodules is 41.67%,83.33% respectively. Both are significant difference (P
