Some examinations involve an injection of contrast media (a special dye that adds further information to the scan). Your Doctor and a Radiologist will decide if it is appropriate to aid the diagnosis. A blood form will be sent to you in the post if you require a blood test before the date of your scan. The blood test is routine and is used to ensure that your kidneys are working normally, as the contrast media is passed from your body in your urine via your kidneys. It is important that the results are available before the date of your appointment so please attend for the blood test before your appointment date. If the blood results are not available for your examination we may have to reschedule your appointment.
The Radiographers will give you information about the injection on the day of your scan and will give you a booklet to take home containing relevant information following the procedure.
You will be asked contrast safety questions and to sign a form to give your permission for us to give you contrast.
Please inform the Radiographers if you have any allergies or have had a reaction to any injections or X-ray dye in the past, or if you are breast feeding.
A cannula (a small sterile plastic tube) will be placed into a vein for the injection, and will be removed once your scan is finished.
