mpMR imaging after EBRT
- Dominant role of the functional sequences of mpMRI
- on DWI: signal characteristics are similar to normal
setting with a focal hypointensity on the ADC map and
hyperintensity on high-b value imaging
- on DCE: although the vascularity of the overall
irradiated prostate decreases with gland atrophy, the
recurrences :
- retain their highly vascular network
- Show the early hyper-enhancement on DCE relative
to the treated prostate.
