My sinusitis symptoms got worse since I moved to a new home further south of florida. I called one of the local hospitals for referrals of ENTs in the area, and made an appointment with one. He prescribed an anti-immflamatory( a corticosteroid) and a tetracycline. But when he told me that I need to get a CAT scan of my sinuses, I objected to schedule for one due to my concern of radiation exposure. I have had a CAT scan of my sinuses in 2008 and two x-rays of my sinuses that are closest to my ears at the emergency a week ago.

Do you think that CAT scans are safe?
