Abstract:
Objective To assess the value of contrast-enhanced computed tomography (CT) in the differentiation of benign solitary pulmonary nodules(SPN) from malignant ones.Methods Thirty-seven patients with solitary pulmonary nodules(≤3 cm phi)were examined by contrast-enhanced CT.Qualitative and quantitative characters of benign and malignant lesions were analysed after administration of Ultravist in order to evaluate the attenuation value of contrast-enhanced CT in the differentiation of benign SPN from malignant ones .Results A threshold value of 30 HU was selected on enhanced CT images to distinguish malignant( CT value≥30 HU)from benign( CT value
