RESUMEN
Cerebral damage secondary to the vasospasm due to subarachnoid hemorrhage (SAH) is an important cause of morbid-mortality. We propose the use of the PET tracer [18F]Fluoromisonidazole to visualize the hypoxia due to the vasospasm. On the other hand [18F]Fluoromisonidazole synthesis process was optimized, avoiding HPLC purification using SPE cartridges instead, and reducing some synthesis steps. [18F]Fluoromisonidazole in vitro stability was tested for ten hours, and in vivo PET/CT images showed higher cerebral uptake in hemorrhagic animals than in control rats.
