Key result
PSOCT birefringence correlates strongly with plaque collagen content and smooth muscle cell density.
Why the study?
A method capable of evaluating plaque collagen content and smooth muscle cell density to assess fibrous cap mechanical fidelity and identify high-risk lesions was needed.
Does polarization-sensitive optical coherence tomography (PSOCT) accurately measure collagen and smooth muscle cell content in atherosclerotic plaques compared to histological staining?

PSOCT accurately measures collagen content and smooth muscle cell density in atherosclerotic plaques, highlighting its potential to evaluate plaque stability.
Nadkarni et al. (2007) conducted a cross-sectional in Atherosclerotic plaques (n=20). Polarization-sensitive optical coherence tomography (PSOCT) vs. Histological staining (picrosirius red and smooth muscle actin) was evaluated on Correlation between PSOCT birefringence and total collagen content (r = 0.67, p=<0.001). Polarization-sensitive optical coherence tomography measurements of birefringence strongly correlated with total collagen content (r=0.67, p<0.001) and smooth muscle cell density (r=0.74, p<0.01).
