Various parameters derived from mono-exponential DWI, IVIM, SEM, DKI and CTRW in breast cancer diagnosis and the prediction of prognostic factors

In the present study, we compared the potential of various diffusion parameters derived from five models in distinguishing breast lesions, including the mono-exponential model (Mono), intravoxel incoherent motion (IVIM) model, diffusion kurtosis imaging (DKI) model, stretched exponential model (SEM), and continuous-time random-walk (CTRW) mode. We found that diffusion-related parameters by the SEM and CTRW models are superior to ADC in discriminating breast lesions. Multiple diffusion parameters by all five diffusion models are related while the information provided is diverse.
