A Saline Sonography is performed by means of an ultrasound scan with injection of saline into the uterine cavity.
A transvaginal scan is initially performed and then the cervix is visualised and a small catheter is inserted through the cervical canal into the uterine cavity. Saline is installed, which distends the uterine cavity and allows visualisation of the cavity itself.
The saline scan is usually performed for diagnostic purposes between approximately day 6 and day 12 of the cycle. The procedure is covered by antibiotics for three days.
The Saline Sonography takes approximately 10 to 15 minutes to perform and the results are available immediately.
