Ultrasound scanning is the use of high-frequency sound waves to produce images of organs, tissues, or blood flow within a patient for diagnostic purposes.
Due to the use of sound waves instead of radiation, ultrasound procedures are believed to be completely safe.
The most common ultrasound procedures are:
Pelvic scans: This scan can be performed both transabdominally and transvaginally.
Transabdominal scans require a full bladder. You will need to consume a litre of water 30 to 60 minutes prior to your scan taking place. The ultrasound probe is pushed against the lower abdominal wall to look down into the pelvis.
A transvaginal (TV) Scan is performed with an empty bladder, using a thin probe inserted into the vagina. This allows detailed information to be obtained by having the probe closer to the pelvic organs.
Abdominal scans: Performed transabdominally, these scans usually involve fasting for four hours before the examination to allow for improved imaging of the liver and gall bladder.
Renal scans: Performed transabdominally with a full bladder, this requires the patient to drink a litre of water 30 to 60 minutes prior to the scan taking place. This scan then helps to assess the kidneys and bladder.
Doppler Venous/arterial scans: Doppler imaging analyses the flow of blood within vessels.
Musculoskeletal scans: These are carried out by a musculoskeletal specialist
