Can a CT scan of the urether, bladder and kidneys still be good enough to show tumours without the use of a contrast dye.
Thank you for contacting Macmillan Cancer support and welcome to the online community.
You have not specified what kind of scan you might have. I can see from your online community entry, that you had a reaction to contrast dye some time ago.
Contrast material is generally used to demonstrate the inner structures of the ureters, bladder and kidneys. The most commonly used contrast material today would still be iodine based, although alternatives have been mentioned in the literature.
It is still possible to get results from scans without contrast, but sometimes it does not give the same details. It depends what exactly your consultant team is looking for and what the indications for your scans are.
It would be best to go back to your team and talk about your concerns with them. They can also discuss alternatives with you.
I hope this is useful for you. You might find it helpful to speak to one of our cancer specialist nurses on our telephone support line on 0808 808 0000. We are available 7 days a week from 8am to 8pm.
