Chemical exchange saturation transfer (CEST) is a new type of MRI technology, can selectively label the exchangeable hydrogen protons in endogenous or exogenous free macromolecules. Intravoxel incoherent motion (IVIM) MRI can be separated to obtain information related to true water molecule diffusion and microcirculation perfusion through double exponential model analysis. Our research shows that CEST and IVIM have similar diagnostic performance in the differential diagnosis of lung squamous cell carcinoma and lung adenocarcinoma.
