The major PET radiopharmaceutical used to measure cerebral perfusion is O-15 H2O.1 While brain perfusion is critical for delivery of all tracers to the brain, the practical application for region cerebral perfusion PET alone is currently mainly limited to the assessment of cerebrovascular disease.Tuesday, 05 Jun 2007 16:32:07 GMT
