In this study, multi-b value Diffusion Weighed imaging models of mono-exponential, bi-exponential (intravoxel incoherent motion, IVIM) and stretched exponential models were discussed in diagnosing endometrial cancer and cervix cancer, in order to find more reliable or more precise method to deal with DWI. The results showed good diagnostic value of Slow ADC in IVIM model, and showed potentially ability of using perfusion fraction as a non invasive method assessing perfusion. While stretched exponential model were questioned by some results from this study.
