PET in Brain Arteriovenous Malformations and Cerebral Proliferative Angiopathy

摘要: A brain arteriovenous malformation (BAVM) is a neurovascular entity that consists of localized dense network abnormal blood vessels (a nidus) holds arteries shunting directly into veins in the absence capillary bed. In their natural history, BAVMs carry risk hemorrhage or other neurological complications, for which reason they are frequently treated. Cerebral proliferative angiopathy (CPA) different type with distinct angiographic and clinical features can be used to differentiate it from classical BAVM. The basic difference between CPA BAVM has normal tissue intermingled its vessels. Treatment by surgery, radiosurgery, embolization consequently harbors high complications. As such, reliable diagnostic discrimination crucial adequately treat patients. However, despite fact some characteristic imaging features, differentiation AVM may difficult. PET as technique reveals functional therefore likely additional value.
