Key result
The Cytoscan Model E-II showed good agreement with intravital fluorescence videomicroscopy for venular red blood cell velocity, though it measured diameters on average 5 microm smaller.
Why the study?
Does the Cytoscan Model E-II provide comparable microcirculation measurements to intravital fluorescence videomicroscopy in awake Syrian hamsters?

Orthogonal polarization spectral imaging via the Cytoscan Model E-II is a valid, dye-free alternative to intravital fluorescence videomicroscopy for measuring microvascular parameters.

Supports dye-free microcirculation assessment in hamster models; leaves open human validation and clinical translation.
Harris et al. (2000) studied Pressure-induced ischemia. Cytoscan Model E-II (orthogonal polarization spectral imaging) vs. Intravital fluorescence videomicroscopy (IFM) was evaluated on Arteriolar diameter, venular diameter and venular red blood cell velocity. The Cytoscan Model E-II showed good agreement with intravital fluorescence videomicroscopy for venular red blood cell velocity, though it measured diameters on average 5 microm smaller.
