In vivo, high-resolution, three-dimensional imaging of port wine stain microvasculature in human skin.
BACKGROUND AND OBJECTIVES Port-wine stain (PWS) is a congenital, progressive vascular malformation of the dermis. The use of optical coherence tomography (OCT) for the characterization of blood vessels in PWS skin has been demonstrated by several groups. In the past few years, advances in OCT technology have greatly increased imaging speed. Sophisticated numerical algorithms have improved the s...
متن کاملHigh-resolution imaging of microvasculature in human skin in-vivo with optical coherence tomography
In this paper, the features of the intensity-based Doppler variance (IBDV) method were analyzed systemically with a flow phantom. The effects of beam scanning density, flow rate and the time interval between neighboring A-lines on the performance of this method were investigated. The IBDV method can be used to quantify the flow rate and its sensitivity can be improved by increasing the time int...
متن کاملAcquired Port-Wine stain: Report of two cases
Acquired port-wine stain is a rare vascular lesion that mimics a congenital port-wine stain clinically and histologically, but is acquired after birth. A survey on more than 60 reported cases in the literature reveals that most of these cases are idiopathic, but some of the cases developed after physical or mechanical trauma, hormonal changes, chronic sun exposure, and medications (OCP, i...
متن کاملA Comparison of Acquired Port-wine Stain with Congenital Port-wine Stain Using an Image Analyzer.
BACKGROUND Recent reports have proposed that there were no differences between acquired port-wine stain (APWS) and congenital port-wine stain (CPWS) except the onset of disease. Pulsed dye laser (PDL) therapy is regarded as the treatment of choice in PWS. Although in some articles, APWS might have shown a better response to PDL than CPWS, this is still controversial. It has been assumed however...
متن کاملCharacterization of port wine stain skin erythema and melanin content using cross-polarized diffuse reflectance imaging.
BACKGROUND AND OBJECTIVES Objective methods to assess quantitatively port wine stain (PWS) blanching in response to laser therapy are needed to improve laser therapeutic outcome. Previous studies have attempted to assess objectively PWS color based on point measurement devices. To date, these approaches have typically been limited by a number of factors such as small test area and need for cont...
