3D Saline Infusion Sonography (3D SIS)

3D Saline Infusion Sonography (3D SIS) is the visualisation of the uterine (womb) cavity, by a 3D ultrasound using normal saline (sterile water solution).

A catheter is introduced into the uterus (womb) via the vagina and an ultrasound probe is then placed in the vagina. When the uterus is visualised normal saline is then injected via the catheter and the results can be seen on the ultrasound screen. 

3D SIS can be carried out to show:

  • any anatomical abnormalities
  • the presence of abnormal lesions within the cavity, such as fibroids, polyps, adhesions, scar tissue etc.
