Measurement of vascular permeability
The analysis of vascular permeability of tumour blood vessels is of interest for the treatment of cancer for 3 main reasons. First, the vascular wall represents a major barrier to the entry of high molecular weight anti-cancer agents into tumour tissue; second, it controls the tumour microenvironment thus affecting tumour progression and third, changes in its barrier function may provide an early indicator of vascular damage following treatment with anti-angiogenic or vascular disrupting drugs. Despite these important factors, tumour vascular permeability has received little attention in terms of the analytic measurements.

We have developed an image processing-based algorithm (Reyes-Aldasoro, et. al., Microcirculation, 2008) to measure the vascular permeability of microvessels to intravenously-administered 40 kDa fluorescein isothiocyanate (FITC) labelled dextran in tumours.
