Would a brain mri with and without contrast show problems with sinuses(cyst or tumors)or do they have to order mri specifically for the sinuses?

Head/neck scans: a CT scan without contrast is used to identify nose/sinus anatomy and membrane swelling and infections. an MRI of the head with and without contrast shows the brain and sinuses, and is useful for outlining growths/tumors.

Most brain MRIs will: encompass some or all of the paranasal sinuses, albeit not in optimal detail. So really the particular MRI would need to be individually assessed to determine whether it is adequate to rule out a sinus mass. The best way to image the sinuses is with a CT or MRI specifically tailored for that purpose.

Sinuses: when you have a head scan either CT or MRI the radiologist will sometimes comment on sinuses. However, to take a complete look at the sinuses usually need a scan ordered specifically for that.

Hi doctors. I'm having a CT scan of the sinuses. The MRI of the brain from December, 2020 found opacification, but no tumor, nor did a visual endoscopy of my sinuses in the office....is it likely that there still may be tumors found on the CT scan?
