Abstrakt

Dynamic optical coherence tomography (D-OCT) is a non-invasive imaging technique, suitable for the study of structural and dynamic features of cutaneous microvasculature. Studies with D-OCT have primarily focused on non-melanoma skin cancer (NMSC), and a reference description of healthy skin is lacking. The aim of the study was to describe the prevalence of standard microvascular features in normal skin. A total of 280 participants without skin disease were D-OCT–scanned on four body locations: three sun-exposed areas and one unexposed: forehead, back of the neck, back of the hand and medial side of the upper arm. Frequencies of standard vascular features were reported, and relations to anatomical location and demographic data were investigated. “Dots,” “lines” and “curves” were the most frequent shapes at 150 μm, 300 μm and 500 μm. “Mottle” was the predominant pattern at 150 μm and 300 μm. “Mesh” was found from 300 μm and primarily found at 500 μm. Regional differences in vascular characteristics were primarily found comparing the medial side of the arm with the other body locations. In normal skin, the most frequent shapes were “dots,” “lines” and “curves,” and “mottle” was present more superficially than “mesh.” In conclusion, regional anatomical differences should be taken into account when evaluating D-OCT images.
