The aim of this study was to assess
if the histogram analysis of mono-exponential, bi-exponential and stretched exponential
models of diffusion-weighted MRI (DW-MRI) parameters can differentiate two
common subtypes of ovarian epithelial cancer: high-grade serous carcinomas (HGSCs)
and clear cell carcinomas(CCCs). Based on an entire-tumour measurement, the
following histogram parameters were derived from ADC, D, D*, F, DDC and α maps,
respectively: the mean of the whole tumor, the 10th percentile and the mean of
the top 10 percent. We concluded that ADC, D, F, DDC and α have showed good
diagnostic performance by analyzing these data.
