Hello. i fear that i am getting too many ct scans. i think this will be my 5th one, and 3rd for head area. i had a massive headache on a plane, and did a ct scan, and another venogran ct right after. now im doin sinus ct tomorrow for same problem ?

CT scans are useful in diagnosing medical problems. Having 3 in a short amount of time to diagnose a serious problem may occasionally be necessary. More important is your lifetime risk from CT's. If you are needing these every year or more, then you might want to discuss the risks with your Dr.

You may be able to avoid the sinus CT by having the prior CT reevaluated and reformated . There will be a charge but it will avoid the radiation. Have your MD check and see if this is possible at the facility that performed your CT. They will need to have kept the original data to be able to do this.
