Ultrasound Sonography

Ultrasound sonography makes use of high frequency sound waves to visualize internal soft tissue structures such as tendons, muscles, joints, vessels, and internal organs. These sound waves are produced by a transducer and are reflected back from the internal tissues at varying speeds owing to the densities of the different tissue structures. The computer attached to this transducer produces images based on the ‘echo pattern’ generated.

What to expect during Ultrasound Imaging?

  • A gel is applied to the skin on the area to be examined to improve the transducer’s contact with the skin.
  • The transducer is pressed against the skin and its angle and positioning is modified to better understand the area(s) of interest.

What preparation is needed?

  • In the case of ultrasonography of the abdomen, the patient should not eat or drink for 8 hours prior to the scan. However, the patient is allowed to drink water.
  • Ultrasound of the pelvic region or urinary bladder bladder requires a full bladder. Drink 1 to 1.5 litres of water 1 hour prior to your test. Do not empty your bladder until the test is complete.

Is there anything else I should know?
You are requested to bring a copy of the medical history of the patient, including recent lab work reports and any previous imaging scans that may have been prescribed by your doctor.
