We report our preliminary results on quantification of glucose and dimethyl sulfoxide (DMSO) diffusion in normal and cancerous human bladder tissues in vitro by using a spectral domain optical coherence tomography (SD-OCT). The permeability coefficients (PCs) of a 30% aqueous solution of glucose are found to be (7.92 ± 0.81) × 10{sup -6} cm s{sup -1} and (1.19 ± 0.13) × 10{sup -5} cm s{sup -1} in normal and cancerous bladder tissues, respectively. The PCs of 50% DMSO are calculated to be (8.99 ± 0.93) × 10{sup -6} cm s{sup -1} and (1.43 ± 0.17) × 10{sup -5} cm s{sup -1} in normal and cancerous bladder tissues, respectively. The obtained results show a statistically significant difference in permeability of normal and cancerous tissue and indicate that the PC of 50% DMSO is about 1.13-and 1.21-fold higher than that of 30% glucose in normal bladder and cancerous bladder tissues, respectively. Thus, the quantitative measurements with the help of PCs from OCT images can be a potentially powerful method for bladder cancer detection. (optical coherence tomography)
