Should I tell the MRI unit about my fear of the scanner before the appointment?

The booking call was almost finished when the administrator asked, "Any questions?" I said no. Then I spent the evening looking at photographs of MRI scanners and feeling trapped just imagining the tunnel.

The scan was ordered to investigate a medical concern. I have not had an MRI before. My brother says telling the unit I am frightened will only delay it, and that I should close my eyes and get it over with.

[NHS advice says to contact the hospital before the appointment if you feel anxious about an MRI or fear small spaces](https://www.nhs.uk/tests-and-treatments/mri-scan/). I want to ask about the process and available support rather than cancel without a conversation.

I have already arranged a day away from work. What would you say in the call so the unit can plan with me, without making promises about what I will tolerate or asking the internet to choose a calming medicine?
