Zusammenfassung

Die optische Kohärenztomographie (OCT) und die konfokale Lasermikroskopie (KLM) sind in der klinischen dermatologischen Routinediagnostik bereits etablierte nichtinvasive Methoden. Während die KLM insbesondere hilfreich bei der Unterscheidung von Naevi und Melanomen ist, eignet sich die OCT vor allem zur Diagnostik und Differenzierung von nichtmelanozytärem Hautkrebs. Die LC-OCT („line-field confocal optical coherence tomography“) hingegen ist ein neues innovatives Verfahren, das über eine bessere zelluläre Auflösung als die OCT und höhere Eindringtiefe als die KLM verfügt. Mit der LC-OCT sind im Vergleich zur KLM auch 3‑D-Aufnahmen in Echtzeit möglich. Sie eignet sich sehr gut zur Untersuchung von Hautläsionen aller Art, da sie die Vorteile von KLM und OCT vereint.

Abstract

Optical coherence tomography (OCT) and confocal laser microscopy (CLSM) are established non-invasive methods in clinical dermatological routine diagnosis. Whereas CLSM is especially useful to distinguish between nevi and melanoma, OCT is suitable for the diagnosis and differentiation of non-melanoma skin cancer. Line-field confocal optical coherence tomography (LC-OCT) is a new innovative device, which has better cellular resolution than OCT and a higher penetration depth than CLSM. Similar to CLSM, LC-OCT also allows 3D images in real time to be taken. Therefore LC-OCT is very useful for the examination of skin lesions of all kinds, since it unites the features of CLSM and OCT.
