| Abstract: | The diffusion weighted imaging(DWI)can reflect the degree of diffusion of water molecules in tissues without contrast enhancement.However,DWI is a mono-exponential model,which cannot separate the pseudo-diffusion from pure molecular diffusion.Intravoxel incoherent motion diffusion-weighted imaging(IVIM-DWI)utilizes a double-exponential model to obtain parameters of pure water molecule diffusion and microcirculatory perfusion-related diffusion,more comprehensively and accurately reflects the complexity of the microstructure of the tumor tissue.In recent years,the application of IVIM-DWI in lung has been gradually increasing and become the focus of lung functional magnetic resonance imaging research.In this paper,we mainly reviewed the technical parameters of IVIM-DWI in lung and related research progress in the diagnosis and treatment of the lung cancer. |
