The study aim to compare the intravoxel incoherent motion (IVIM) and DCE-MRI for distinguishing benign pulmonary nodules and lung cancer and evaluate the diagnostic performance of two methods. We found ADCtotal,D,D*from IVIM and Tmax,SLE from DCE-MRI valuable for differential diagnosis ,with D and Tmax have better sensitivity and accuracy.But parameters between the two methods show poor correlation.Combination of IVIM and DCE-MRI can get excellent diagnostic performance.
