Pelvic Ultrasound

Pelvic ultrasound is a common gynecological examination that involves a non-invasive diagnostic procedure. It utilises sound waves to visualise and assess the health of pelvic organs and structures, including the uterus and ovaries. It is a tool for early detection of gynecological conditions such as ovarian cancer and endometriosis. Pelvic ultrasound offers higher accuracy compared to manual palpation by doctors.

There are two main types of pelvic ultrasound: abdominal ultrasound and transvaginal ultrasound, distinguished by the position and type of probe used. Abdominal ultrasound involves placing the probe on the abdomen, where the sound waves pass through the abdominal wall and bladder to visualise the uterus and ovaries. Transvaginal ultrasound requires inserting a probe into the vagina, allowing for closer proximity to the uterus and ovaries. The images obtained with transvaginal ultrasound are generally clearer, resulting in more accurate diagnostic outcomes. However, this type of examination may not be suitable for women who have not engaged in sexual intercourse. In this situation, the doctor may discuss the option of a transrectal scan for better assessment in case transabdominal scan does not yield satisfactory findings.    

3-dimensional (3D) pelvic ultrasound

A 3D pelvic ultrasound is an advanced imaging technique that utilises three-dimensional technology to create detailed images of the pelvic organs and structures. It provides a more comprehensive view of the pelvic region compared to traditional two-dimensional (2D) ultrasound.

During a 3D pelvic ultrasound, sound waves are directed into the pelvic area using a transducer, similar to a regular pelvic ultrasound. However, in 3D ultrasound, multiple images are captured from different angles, allowing the computer to construct a three-dimensional representation of the pelvic organs and tissues.

The benefits of 3D pelvic ultrasound include:

1. Improved visualisation: 3D ultrasound provides a more detailed and realistic representation of the pelvic anatomy, allowing healthcare professionals to observe the structures from different angles and perspectives.
2. Enhanced diagnostic accuracy: The additional information provided by 3D imaging can aid in the detection and characterisation of abnormalities in the pelvic region. It can help identify conditions such as uterine septum, uterine fibroids, ovarian cysts, and other abnormalities in the fallopian tubes or uterus.
