  • Title: Expanding applications, accuracy, and interpretation of laser speckle contrast imaging of cerebral blood flow.
    Author: Kazmi SM, Richards LM, Schrandt CJ, Davis MA, Dunn AK.
    Journal: J Cereb Blood Flow Metab; 2015 Jul; 35(7):1076-84. PubMed ID: 25944593.
    Abstract:
    Laser speckle contrast imaging (LSCI) provides a rapid characterization of cortical flow dynamics for functional monitoring of the microcirculation. The technique stems from interactions of laser light with moving particles. These interactions encode the encountered Doppler phenomena within a random interference pattern imaged in widefield, known as laser speckle. Studies of neurovascular function and coupling with LSCI have benefited from the real-time characterization of functional dynamics in the laboratory setting through quantification of perfusion dynamics. While the technique has largely been relegated to acute small animal imaging, its scalability is being assessed and characterized for both chronic and clinical neurovascular imaging.
