Introduction to Head & Neck Ultrasound
Slide2Learning Objectives
To recognize the indications for and clinical utility of H&N ultrasound.
To identify normal H&N anatomy
To know basic ultrasound machine capabilities and control functions
Slide3What is Ultrasound?
Sound waves: 2-10 MHzWaves are propagated through different tissues at different velocitiesBoundary of two tissues causes impedance mismatch Sound waves are reflected back at different frequencies Differentiation of tissues
Slide4Slide5Slide6Piezoelectric Crystals
Converts electrical current into sound waves
Converts the reflected waves (acoustic echoes) into a grayscale image
Slide7What can we see?
Thyroid gland: nodules, goiter
Parotid glands
Submandibular glands
Enlarged or pathologic lymph nodes
