Sonohysterography, also known as saline infusion sonography, is a special, minimally invasive ultrasound technique. It provides pictures of the inside of a woman’s uterus. A Doppler ultrasound study may be part of a sonohysterography examination.
It is a valuable technique for evaluating unexplained vaginal bleeding that may be the result of uterine abnormalities such as:
- endometrial atrophy
- endometrial adhesions (or scarring)
- malignant lesions/masses
- congenital defects
Sonohysterography is also used to investigate uterine abnormalities in women who experience infertility or multiple miscarriages.
