Fluorescence monitoring and effect of photodynamic therapy for port wine stains

It is known that fluctuations in the treatment outcome of photodynamic therapy between patients are related to the concentration of photosensitizer in target tissue. Researchers recently carried out a study in order to establish a fluorescence method not only providing a semi-quantitative measurement of photosensitizer concentration but also predicting the efficacy of PDT for port wine stains.
