Time

The scan time itself is usually only a few seconds, however including positioning, injections etc. you will be in the scan room between 5-20 mins.

You will need at least 30 mins from the time you arrive until you are completely finished. Sometimes this will be longer if a more complex examination is needed or complications arise.

After Your Examination

If you have had contrast, you will be required to stay for at least 15 mins after your study so that we may monitor you for the rare case you have an allergic reaction to the contrast.

IV Contrast

Contrast * – is an iodine based clear substance that is given via a needle in the arm. It is used to help show blood vessels, better visualise some organs and assist with the diagnosis of pathology.

In some instances allergic reactions to contrast material can occur, but significant reactions are rare, and generally respond to antihistamines. Our staff members are equipped and trained to treat contrast reactions.

When you arrive for your examination you will be given further information regarding this.
