A CT of the extremities produces detailed pictures of the soft tissues, joints and bones of your arms, legs, hands or feet. CT imaging is more detailed than images obtained from conventional x-rays. The scan is also useful as a diagnostic tool because of its ability to display different types of tissue in the same region, including bone, muscle, soft tissue, and blood vessels.

CT scanning of the extremities may be recommended to evaluate swelling, pain, trauma, a mass or possible fracture.

Lake Imaging performs CT Extremity examinations at the following locations:

What to expect during my procedure

You will then be asked a few safety questions before being asked to lie flat on the CT examination table with your head resting on a special cradle. You will need to keep very still for the duration of the scan, as the table moves through the gantry opening and the image data is acquired. You may hear a humming noise during the scan, but no moving parts will touch you.

The CT scan will take just a few minutes.

Risks and side effects

CT scans involve the use of ionising radiation.  CT scans will only be performed when any potential risks are far outweighed by the benefits to the patient.
