Reemember to make it light, helps not to stress.
The technicians are bored, so joking some times helps.
When I had a knee MRI for a Baker’s cyst, those behind the knee, I was looking at the picture and said, “wow, that is a big one” and the technician said “that is the biggest one I have seen”.
I said " short as I am, at least I can brag about my Baker’s cyst being bigger than anyone else’s".
We had a good laugh about that.
They really are not supposed to make comments, but some times it is ok.
I bet you will do fine.
Oh, they are used to growling stomachs, I think.
