Here’s an ultrasound scanning tip on how to recognize and overcome anisotropy, a common imaging artifact associated with MSK ultrasound. Demonstrated by Lori Green, BA, RT, RDMS, RDCS, RVT, Program Director at Gulfcoast Ultrasound Institute.
Anisotropy is a common artifact seen in musculoskeletal ultrasound that occurs when the ultrasound beam encounters a structure at a non-perpendicular angle. The artifact results with a loss of echogenicity in structure. We see anisotropy more commonly in tendons and ligaments, but it also occurs in muscle and nerves to a lesser extent.
