Validation of kinetic modeling of [15O]H2O PET using an image derived input function on hybrid PET/MRI
NeuroImage(2021)
摘要
In present study we aimed to validate the use of image-derived input functions (IDIF) in the kinetic modeling of cerebral blood flow (CBF) measured by [15O]H2O PET by comparing with the accepted reference standard arterial input function (AIF). Additional comparisons were made to mean cohort AIF and CBF values acquired by methodologically independent phase-contrast mapping (PCM) MRI.
