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[32] require radioactive material that is not recommended for use in infants.[33] Doppler ultrasound and cerebral oximetry are noninvasive, indirect measures of cerebral blood flow in infants.[33] Doppler ultrasound focuses on provider-selected cerebral arteries or veins to measure cerebral blood flow,[21] but it requires an ultrasound technician at the bedside to gather data that must then be interpreted by a radiologist.[34] 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.
