We present a simple method by which investigators performing multi-echo DSC-MRI perfusion studies can identify voxels saturating into the noise floor at later echo times, and show the effect of removing these voxels from analysis on AIF estimation. Furthermore, our study evaluates these methods in a population of pediatric patients, demonstrating their applicability in an actual clinical context.
