Validity and Advantages of Three-Dimensional High-Frequency Ultrasound in Dermatological Evaluation

The study demonstrates the potential of three-dimensional high-frequency ultrasound (3D-HFUS) as a noninvasive tool for dermatological evaluations, particularly for inflammatory hair loss diseases like alopecia areata and lichen planopilaris. It provides detailed images of skin structures, improving visualization of tumor margins and hair follicle densities, which are crucial for diagnosis and disease activity assessment. The study involved 10 healthy volunteers and several cases of skin conditions, showing that 3D-HFUS correlates well with histopathological findings and could reduce the need for invasive biopsies, although further data is needed for broader clinical use.
