Cerebral Anatomy, Hemodynamics and Metabolism

An MRI scan takes pictures of the brain and heart using a magnet and radio waves. During scanning, measurements of oxygen delivery to the brain will be obtained (CMRO2) as well as evaluation of the heart as it relates to the brain. During the scan patients will be monitored for safety by ECG, blood pressure, television camera, pulse oximetry, and carbon dioxide measurements. Cardiac anesthesiologist and cardiologist will be present.

Quantitative ND tests and standardized rating scales will be used in the areas of intellectual, adaptive, visual motor skills, academic achievement in math and reading, attention and executive functioning , motor skills, memory, language, social skills and behavior. Neurodevelopmental Testing will last approximately 3.5-4 hours. Testing will be done through the Neurobehavioral Core at CHOP. Breaks will be taken as needed and a one hour lunch break will be taken, if applicable. ND testing will be performed prior to MRI (if on the same day) or on a different day than the MRI to promote engagement and best performance.
