hi guys has anyone ever had a brain MRI scan? about 6 months ago I had one for headaches which came back normal, I've got a hard lump behind my left earlobe which I've recently starting to become worried about and I was wondering this - what exactly does a 'brain mri' cover? I was in the machine for about 20 minutes, and was wondering do they scan the full head like round the ears etc or do they purely look at the brain and ignore everything else? the lumps been there at least 2 years maybe longer but I want to know if the scanner would have picked up anything bad around that area!

thank you
