X-ray Phase Contrast CT (PCI-CT) is an experimental imaging methodology, which simultaneously provides micrometric spatial resolution, high soft-tissue sensitivity and $ex vivo$ full-organ rodent brain coverage without any need for sample dissection, staining/labeling or contrast agent injection. We explore here the benefits and limitations of PCI-CT use for the $in vitro$ imaging of normal and cancerous brain neuro-morphology after $in vivo$ treatment with synchrotron-generated X-ray Microbeam Radiation Therapy (MRT), a spatially fractionated experimental high-dose radiosurgery. The goals are the visualization of MRT treatment effects on nervous tissue, and qualitative comparison of results to histology and high-field MRI.
