When ultrasounding a limb for tendonitis,

______ injuries will be HYPOechoic, where as

________ injuries will be HYPER or HETEROechoic

Answer 20

Acute- HYPO

Chronic- HYPER/HETERO

Question 21

A reduced striated pattern indicates _______ tendon injury

where as an

irregular striated pattern indicates ______ tendon injury

Answer 21

REDUCED striated = ACUTE

T/F:

You suspect a tendon injury where the DDFT inserts onto P3.

The best diagnostic tool to use here is Ultrasound

FALSE!

This is blocked by the hoof capsule, so will have to use MRI
