Do metalloporphyrin antioxidants ameliorate normal tissue radiation damage in rat brain?
Metalloporphyrin antioxidants merit further exploration as adjunctive radioprotectants for cranial radiotherapy/radiosurgery applications, although the potential for tumour protection must be carefully considered.
Diffusion-weighted imaging characteristics differ between PFO and dissection, suggesting differences in the pathogenesis of brain infarction between these aetiologies. A single non-territorial infarct seems to favour PFO as stroke aetiology. Whether this or other features are distinctive enough to diagnose PFO or dissection in individual patients requires further testing.
