Abstract:Real time investigation of cerebral blood flow (CBF), and oxy/deoxy hemoglobin volume (HbO,HbR) dynamics has been difficult until recently due to limited spatial and temporal resolution of techniques like laser Doppler flowmetry and MRI. This is especially true for studies of disease models in small animals, owing to the fine structure of the cerebral vasculature. The combination of laser speckle flowmetry (LSF) and multi-spectral reflectance imaging (MSRI) yields high resolution spatio-temporal maps of hemody… Show more
