The differential diagnosis of benign and malignant focal lesions of the lung is a hot and difficult problem in daily chest imaging. The purpose of our study was to evaluate the potential of intravoxel incoherent motion (IVIM)–derived parameters as well as apparent diffusion coefficient (ADC) in differentiating solitary pulmonary lesions. The results demonstrate that IVIM-DWI could be more helpful for distinguishing malignant from benign lesions in lung. D has the best diagnostic efficiency.
