: Ultrasound is superior to clinical exams for staging, as it can detect subclinical fistulas and fluid collections. Atlas of Dermatologic Ultrasound

High-frequency ultrasound (HFUS) uses sound waves to create real-time images of the skin layers. Atlas of Dermatologic Ultrasound

: Standard dermatologic exams require probes of at least 15 MHz ; ultra-high frequency (UHFUS) can reach up to 70 MHz for viewing minute structures like hair tracts. Layer Echogenicity : Epidermis : Appears as a bright, hyperechoic line. Atlas of Dermatologic Ultrasound
