What Is the Endometrial Stripe?
The endometrium is the mucous membrane lining of the uterus. It is sometimes referred to as the endometrial stripe because it shows up as a dark stripe on transvaginal ultrasound. The size of the stripe, or the thickness of the endometrium, can be an indicator of endometrial abnormality, though this must be considered along with other signs or symptoms a woman may be experiencing.
