Quantitative diffusion and Kurtosis MRI in the evaluation of endometrial cancer: validation with histopathology

To ameliorate the Endometrial cancer (EC) diagnosis and prognosis, IVIM and KURTOSIS models were used to elaborate DWIs obtained from 18 with EC and 20 healthy women. The b-values were 0,30,50,150,500,800,1000,1500,2000,2500s/mm2. DWIs were noise-corrected considering a homomorphic approach. For each EC subject, ROI in the tumor (T) and peritumoral (PT) area were analysed and endometrial area in healthy (H) subjects was also obtained. IVIM and Kurtosis parameters were quantified. K, which quantifies tissue's complexity, is significantly higher in T and PT than in H. f is higher in PT compared to the other areas, highlighting the perfusive nature of EC.
