Despite the introduction of new treatment options in recent years, the survival rates of patients with lung adenocarcinoma (LUAD) remain unsatisfactory. In order to care for patients effectively, clear insight into the processes of ventilation and perfusion of LUAD is required. In this work, Intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) was used to monitor the blood flow while oxygen-enhanced MRI (OE-MRI) was used to measure the ventilation. Our results showed that the combined measurement of OE-MRI and IVIM-DWI may serve as a promising method for the noninvasive assessment of lung function and classification of LUAD subtype.
