Cerebral-tissue XeCI excimer laser photoablation: preliminary in-vivo studies in the rat brain

Deep brain tissue lesions produced by XeCl excimer laser were studied in 14 rats. Fiberoptic was stereotactically implanted and the lesion was produced by one pulse. MRI and histological controls were performed at various dates following the lesion. The findings are relevant to other lesion procedures. Some XeCl laser properties seem useful in stereotactical procedures.
