Ultrasonography: Abnormal Conditions
Artifacts.
The bright white horizontal lines in the uterus are specular reflections. These artifacts occur when two very different densities are parallel to one another and the ultrasound beam hits them perpendicularly. These artifacts are common in the estrual uterus and should not be confused with pathology.
