Abstract
We report an innovative, wearable, multiscale diffuse speckle contrast flowmetry (DSCF) probe for continuous transcranial imaging of cerebral blood flow (CBF) in animal s. Significant reductions in CBF during transient ligation of bilateral common carotid arteries were detected by DSCF (-35±13% in two mice and -59% in a piglet), meeting clinical expectations. Results from DSCF and an established CBF measurement device, diffuse correlation spectroscopy, were consistent and significantly correlated. With further optimization and validation in animals and humans, we expect to ultimately offer a unique, noninvasive, low-cost, and fast brain imaging tool for basic neuroscience research and clinical applications.
