We show a significant difference between the vascular characteristics of the studied PWS and hemangiomas lesions. We believe that OCT complemented by Doppler OCT could be a promising method for future non-invasive diagnosis and monitoring of some vascular lesions.

Non-invasive real-time imaging of vascular lesions is performed with OCT, with 10-20 micrometers resolutions at 1mm depth. The images reveal different skin layers and blood vessels (Doppler effect), the growth of which indicates vascular tumor.
