Detection of cavernous malformations after whole-brain radiotherapy in primitive neuroectodermal tumor patients—comparing susceptibility-weighted imaging and T2 gradient-echo sequences

Purpose The aim of this retrospective study is to investigate the value of the susceptibility-weighted imaging (SWI) sequence compared to gradient echo (GRE) in the detection and follow-up of cavernous malformations in patients who underwent whole-brain irradiation as part of their medulloblastoma treatment.
