{Reference Type}: Journal Article {Title}: How to Start on Dermatologic Ultrasound: Basic Anatomical Concepts, Guidelines, Technical Considerations, and Best Tips. {Author}: Gonzalez C;Wortsman X; {Journal}: Semin Ultrasound CT MR {Volume}: 45 {Issue}: 3 {Year}: 2024 Jun 4 {Factor}: 1.641 {DOI}: 10.1053/j.sult.2023.11.001 {Abstract}: Dermatologic ultrasound has grown exponentially during the last decades and has passed from the experimental phase to the routine daily practice in multiple countries. The performance of this imaging technique requires color Doppler ultrasound devices working with high-frequency probes, a trained operator on imaging and dermatologic conditions, and the performance of standardized protocols for obtaining the anatomical data properly. In this review, we analyze the ultrasonographic anatomy of the skin, hair, and nails, the technical requirements and considerations, the guidelines, and the recommended protocols, and provide the best tips for practicing this type of examination confidently.
