Will a Limited CT Sinus Scan without contrast show if I have Mastoiditis? One was ordered for me. Or do I need a more detailed test? Having a hard time convincing a dr that something is wrong, but I have had three sinus surgeries in the past, mastoiditis showed on a brain Mir last year am No no one said anything, I had a bad cold in the beginning of this year and my left ear is not seeming to clear. I have a heavy feeling, pain, ear plugged , fluid in ear, have been given nasal sprays and steroids.
