Question 3

What are the ultrasound and MRI findings of tendon injuries?

Answer 3

MRI - Grade I injury, or mild sprain, is described as abnormal increased signal around an otherwise normalappearing ligament. Grade II injury is consistent with a severe sprain and demonstrates abnormal thickening and/or abnormal signal within the ligament. Grade III injury represents a complete disruption of the ligament.

US - Tears are demonstrated as a hypoechoic gap in the tendon, often with fluid in the tendon sheath. Tendinitis is seen as increased thickness of the tendon with altered echogenicity, either focally or diffusely.
