In this article we present a method for the objective assessment and monitoring of tissue blood supply using a specially developed endoscopic imaging colorimeter that enables quantitative color modeling of the back-scattered light during endoscopic examination. Tissue blood volume changes in the nasal mucosa, induced by xylometazoline hydrochloride nasal spray, were evaluated with this method. It was found that quantitative imaging provides sensitive, reproducible, and reliable means for the monitoring and mapping of tissue blood supply and is easy to use routinely. The results showed that saturation decreases with time, being the most sensitive color parameter to the vasoconstriction procedure. It appears that objective indexes for optical tissue characterization and analysis may be promising in the understanding of the pathophysiology of tissue changes and in the objective evaluation of their response to different therapeutic schemes. |
