Hi

Is a cat scan enough to show a brain tumour or do I need an mri?

I had a cat scan in April as have been having same right sided headache for over a year but last few weeks it has got worse and comes with nausea.

Cat scan was normal

Saw a neurologist the other day and hes happy its chronic daily headache or a form of migraine.

I'm worried they have missed something

Any advice please x
