Measurement of Cerebral Blood Flow and Cerebral Oxygenation
Actual cerebral blood flow is difficult to measure in premature infants because the most accurate measurement methods including single-photon emission computed tomography, positron emission tomography, and radionuclide angiography require radioactive material that is not recommended for use in infants. Doppler ultrasound and cerebral oximetry are noninvasive, indirect measures of cerebral blood flow in infants. Doppler ultrasound focuses on provider-selected cerebral arteries or veins to measure cerebral blood flow, but it requires an ultrasound technician at the bedside to gather data that must then be interpreted by a radiologist. In addition, studies using Doppler ultrasound do not provide guidance for continuous clinical decision making. Cerebral oximetery measures cerebral oxygenation without use of radioactive materials[33,35] or requiring additional personnel for interpretation at the bedside.
