Discovering a new anatomy: exploration of oral mucosa with ultra-high frequency ultrasound. [PDF]

Dentomaxillofac Radiol, 2020
Objectives: Ultra-high frequency ultrasound (UHFUS) is a recently developed diagnostic technique involving the use of ultrasound frequencies up to 70 MHz, allowing to obtain 30 µm resolution of targets located within 1 cm from the surface. Oral mucosa can be affected by diverse pathological conditions, which are currently investigated by means of ...
