Ultrasound of minor adductor strain

The ultrasound image above shows a small intramuscular bleed and tissue irregularities around the musculotendinous junction consistent with an adductor strain. To the right of the image is an example of anisotropy: a hypoechoic region that appears when sound waves are not aligned with the ultrasound probe. This may be due to loss of contact between the ultrasound probe and curved areas of the body. Anisotropy can be confused with signs of injury.
