Is no news always good news on a brain mri scan?

I called last week and they hadn't got the results yet and they said if they found anything they would call me. I called back and they said that the results would be discussed at my follow up appointment. So since they didn't call me and I called them is no news good news. I know something has to be wrong with because I'm having tons of neurological symptons including seizures. What do you think?
