The optical absorption and transport scattering coefficients of normal prostate tissue have been measured in vivo in dogs. The measurements were made at 630 nm before and during treatment by Photofin photodynamic therapy using interstitial optical fiber fluence-rate detectors. Corresponding measurements were made ex vivo, at 1 week after treatment, in the contralateral lobe. The optical properties were derived by applying a diffusion theory model to the fluence rates measured at two different source-detector fiber distances. While the in vivo pretreatment and in vivo contralateral post-treatment absorption and scattering values are self-consistent and in agreement with published data, significant changes were observed in the light fluence rates, and hence in the derived optical properties, during light irradiation. The possible causes of such changes are considered, and the implications for light dosimetry in photodynamic therapy are discussed.
