Abstract

Percutaneous single-fiber spectroscopy was applied in vivo to livers of rats fed a control diet (8 rats) and a methionine-choline-deficient diet (16 rats). Lipid accumulation was associated with changes in spectroscopy-extracted scattering parameters.

Abstract

Spectral trans-rectal ultrasound-coupled optical tomography at 785nm and 830nm has revealed non-invasively longitudinal elevation of total hemoglobin concentration associated with development of transmissible venereal tumors in canine prostate over a 6-week time-course.
