IV Contrast and if you need it
Some CT scans require an IV contrast injection to help certain organs, blood vessels and tissues show more clearly on the images.
Contrast is given through a small cannula placed into a vein, usually in your arm.
Not every CT scan needs contrast. Whether you require it depends on the type of scan, the reason for your examination and your medical history. Our team will review your referral and determine whether IV contrast is appropriate.
Before receiving contrast, we will ask you some safety questions, including about allergies, kidney function and relevant medical conditions. In some cases, a recent blood test to check your kidney function may be required.
During the injection, it is common to experience a temporary warm sensation or metallic taste. This usually passes within a minute or two.
If you have any concerns about IV contrast or have experienced a previous reaction to contrast, please let our team know when booking your appointment.
CT Contrast & Our Injector
For some CT scans, an iodine-based contrast called Omnipaque (iohexol) may be given through a small cannula in your arm. The contrast helps certain organs, blood vessels and tissues show more clearly on the CT images, allowing the radiologist to see greater detail.
At Goulburn Radiology, contrast is administered using our CT contrast injector, which delivers the contrast at a controlled rate and volume specifically selected for your examination.
Not every CT scan requires contrast. Our team will review your referral and relevant medical history to determine whether contrast is appropriate for your scan. If contrast is required, we’ll explain the process and complete the necessary safety checks with you beforehand.
