Thickness measurements of melanocytic skin lesions: method comparison between histology and high-frequency ultrasound using 20MHz and 100MHz ultrasound transducers

Problemstellung: The aim of this pilot study was to evaluate the accuracy of 100MHz-ultrasound (US) for the determination of mean vertical tumor thickness (TT) of melanocytic nevi (MN), compared with 20MHz-US and histological findings, by applying appropriate statistical methods. Patienten und Methode: In this prospective study 21 patients with pigmented skin tumors were referred to the Department of Dermatology, Ruhr-University Bochum (Germany) for further evaluation and management. The study was conducted in the light of the declaration of Helsinki. All patients who participated in the investigation signed an…
