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.


We understand having a medical procedure can sometimes be a confusing and worrisome time. We are here to help you, so if you are unsure about any aspect relating to your examination, please raise your concerns with us at any time and we will do our best to assist you.

Although we are happy to answer questions, you will need to discuss the results of your procedure directly with your referrer.
