MR-Derived Cerebral Oxygen Metabolism underlying Ischemic Vulnerability in Sickle Cell Disease
Abstract: Sickle cell anemia (SCA) affects one in 1000 individuals worldwide, causing multi-organ ischemia, long-term disability, and premature death, with a life expectancy of 42 years. Among its complications, cerebral infarction and cognitive disability are prevalent and increase with age, with > 50% of young adults having silent infarcts. Great headway has been made in pediatric SCA using neuroimaging screening tools to select high-risk children, yet adults remain understudied. As the brain demands disproportionately more oxygen than other organs at ~20% of total blood supply (but only 2% of body weight), low arterial oxygen content (CaO2) due to anemia, places the sickle cell brain at…
