I also have BRCA2 and my first breast MRI today. I found out I had BRCA2 at the end of October 2024 so it took around 3 months to have the MRI under the very high risk screening programme. I was a bit nervous but it was fine, here is the breakdown of what happened:
Arrived at the MRI suite 30 mins before the scan as requested. Filled in some forms to consent to using contrast dye and to take a background health check.
A nurse took me to a changing room, ran through my answers to the forms and gave me 2 gowns to change into. I kept everything on below the waist (just made sure there was no metal on my trousers), took all my jewellery and piercings out. The nurse then showed me to some lockers to put my bag and clothes in.
A different nurse took me through to the pre scan/recovery room. She checked my forms again and inserted a canula in my inner right elbow. She tested the canula with some saline solution and asked me what music I wanted to listen to during the scan.
I was then taken to the MRI room next door. I took off the first gown and the kept the other one on - wearing it like an open jacket. The nurse was in the room with me along with a (female) radiographer. She explained I need to lie face down with my breast in two holes and my arms above my head resting on the bed, they connected the bag of contrast dye to my canula. There was a comfortable padded bit to lay your face on and a pillow under your lower legs. All you can see is the plastic bit of the bed. They put ear plugs in you and then some over the head ear phones and started playing the music I requested. They placed a squeezy pump in my left hand that I could press as an alarm/to speak to the staff. I was rolled in to the machine and the MRI started. Some of it was quite noisy, it sounded like an old dial up modem. I think it lasted about 20 mins and the last 5 mins the nurse checked in on me and told me the contrast dye was going to be inserted and it might feel cold. The last 5 mins the machine vibrated a bit. When it was done they rolled me out, took the earplugs and headphones off. I got up and they gave me the other gown to put back on, removed the canula and I was free to go back to the lockers, get changed in the changing room and leave.
Before the MRI I watched some youtube videos to get an idea of what it would be like and how noisy it was and that helped prepare me.
