A member asked:

Ive had constant headaches for months, the mri showed up normal, i asked my doctor today if i could get checked for a sinus infection, since yrs ago i had a headache for a yr and a half, and thats what it was, can an infection show up on a cat scan?

Headache ?'s: A persistent headache with a negative MRI may result from sinus infection. A CT is not necessary to diagnose this condition , as simple "plain films" ( Waters/Towns views) will be adequate to direct therapy.

Considerations : CAT scan is valuable for sinus views but you might benefit from evaluation of TMJ & dental problems, ?giant cell arthritis, cervical spondylosis, cerebral ischemia, and migraine Maybe a neurologist?
