Abstract

Background: Dynamic optical coherence tomography (D-OCT) has recently been introduced in dermatology. In contrast to ‘Standard’ OCT imaging, which exclusively relies on the morphological analysis of the tissue, D-OCT allows the in vivo visualization of blood flow. Preliminary D-OCT data showed differences in the vascularization of nevus to melanoma transition, suggesting that this technology may help to differentiate between benign and malignant lesions. Objective: Several factors may influence the quality of D-OCT imaging. Therefore, standard operating procedures as well as a common terminology are required for better validation and comparison of the images. Methods: Here, we present practical guidelines for optimal image acquisition and a proposed terminology on vascular patterns observed by D-OCT. Results: Dynamic OCT allows the morphologic distinction of different vascular shapes (e.g. dots, blobs, curves, lines), their distribution and organization within skin lesions. Conclusion: D-OCT adds functional information on skin microvasculature and the vascular networks within lesions.
