Preparing for your scan
The unit's own guides, so you can read them before your appointment rather than only in the envelope that arrives with it. 2 are available in Welsh as well as English.
What is an MRI scan?
A guide to your MRI scan: how it works, how to prepare, what happens on the day, and when you get your results.
What is a CT scan?
A guide to your CT scan: how it works, the injection, how to prepare, and what happens on the day.
Prostate MRI scan
A guide to a prostate MRI. The same scan as any other MRI, with one difference: no injection is needed.
CT scan of the heart: how to prepare
Preparation for a cardiac CT. There are things to do and avoid in the 48 and 24 hours before your appointment, so please read this in good time.
Contrast extravasation: what to do at home
Aftercare if contrast leaked from the vein during your scan. What to do at home, and the symptoms that mean you should contact us.
Call the unit on 01792 606420. If you cannot attend, please ring as soon as you can so the appointment can go to someone else.
These guides are produced by the Clinical Imaging Facility at Swansea University, Clinical Imaging Facility, ILS 2, Ground Floor. The Facility joins the Prime Health network from 1 November 2026.
