Polarization-sensitive optical coherence tomography-based imaging, parameterization, and quantification of human cartilage degeneration

Abstract: Polarization-sensitive optical coherence tomography (PS-OCT) is a light-based, high-resolution, real-time, noninvasive, and nondestructive imaging modality yielding quasimicroscopic cross-sectional images of cartilage. As yet, comprehensive parameterization and quantification of birefringence and tissue properties have not been performed on human cartilage. PS-OCT and algorithm-based image analysis were used to objectively grade human cartilage degeneration in terms of surface irregularity, tissue homogeneity,… Show more

“…In dermatology PS-OCT has also been used to asses dermal photoageing [155], and for the identification and delineation of basal cell carcinoma [156]. In osteoarthritis, PS-OCT has been used for the assessment of cartilage [157][158][159][160][161].…”

“…Similar observations have also been reported by others that the phase retardation in the deep area may accumulate relatively fast in some locations of cartilage samples. 15,26 However, in some other reported literature, 14,16,20 low birefringence has been found in deep zone at normal incidence. The difference in the results shows that the quantification of birefringence in the deep zone is quite sensitive, and it may depend on the types of samples, topographical locations, illumination angles, etc.…”

“…In Ref. 16, moderately degenerated cartilage samples were obtained from the central lateral femoral condyles of human patients. In an ideal model where the collagen fibers are aligned perfectly perpendicular to the tissue surface in the deep zone, the birefringence should be low in the deep zone when the incident light is exactly parallel with the fiber orientation under normal incidence.…”

“…Polarization-sensitive OCT (PSOCT), a functional extension of OCT, has been explored to study the alterations of structure-induced birefringence associated with early OA. [26][27][28] PSOCT obtains the images of phase retardation and optic axis using polarized incident light and polarization-sensitive detection. Although studies have shown the potential of PSOCT for revealing the loss of collagen (i.e., decease in birefringence) in damaged cartilage, 18,19,26,29 the usefulness of PSOCT for characterization of cartilage degeneration remains controversial.…”
