Gynaecological Imaging & Intervention
Ultrasound refers to sound waves with a high frequency. During an ultrasound exam, these sound waves create images on a screen that display the inside of your body, allowing areas of pain, swelling or infection to be directly assessed in real-time.
Pelvic Ultrasound
Gynaecologic ultrasound is used for assessing the female pelvic organs.
Both a transabdominal and a transvaginal scan will be performed in most cases. The best view of the pelvic organs is obtained with a transvaginal ultrasound scan.
During the transabdominal ultrasound, warm gel is applied to your abdomen before our imaging technician places the probe on the abdominal surface and applies pressure to obtain images of the pelvic organs.
During the transvaginal ultrasound, a thin probe is introduced a short distance into the vagina to view the uterus and ovaries. This is a simple and safe procedure.
Transvaginal scans are completely at the discretion of the patient and written consent is required.
At all times, a patient’s dignity and privacy is protected. You are welcome to invite a chaperone into the room for this examination.
Sonohysterography
Sonohysterography is a technique used to assist with diagnosing unexplained vaginal bleeding or to assess abnormalities of the uterus and endometrium.
Similar to a transvaginal ultrasound, Sonohysterography involves the insertion of a thin transducer into the vagina
In conjunction with a transvaginal ultrasound, a catheter is inserted into the cervix and a small amount of sterile saline is injected into the cavity of the uterus. The saline infusion will expand your uterine cavity which provides us with an excellent contrast to the lining and therefore a good visualisation of uterine and endometrial pathology.
Tubal Patency Assessment
Tubal assessment may be recommended in some women who are having difficulty conceiving. This imaging procedure examines the patency of the fallopian tubes. That is, whether the fallopian tubes leading from the ovaries to the uterus are clear and unimpeded for the passage of sperm and ovum.
A preliminary gynaecological ultrasound will be performed prior to the procedure to assess the pelvic anatomy and allow for appropriate procedural planning.
A speculum is passed into the vagina, like a PAP smear and a thin catheter is then passed through the cervix into the uterine cavity. Once in place, a small balloon at the tip of the catheter is inflated to keep it in place.
The speculum is removed, and the ultrasound probe is reinserted into the vagina.
The contrast medium is then prepared and injected through the catheter and the tubes are examined. Contrast should be seen flowing through the fallopian tube and spilling around the ovary on both sides.
