How many days before CT scan (for head-routine and sinuses ) shall a person not to smoke cigarette & weed inorder not to be founded & interfere result?

Don't understand ?: there is no way that a CT scan can determine whether someone had cigarettes or weed prior to the testing, unless the smell is on your clothes/hair/breath and the technician tells on you, or you smoke it inside the machine.

Is image guided sinus surgery like having another CT scan of head/sinuses? Should one worry about commulative radiological exposure?

Yes and no: Image guided sinus surgery allows your surgeon to more accurately identify where they are working in an effort to reduce the chance of surgical injury and to assure that the sinus issues you suffer from are treated as effectively as possible. This does require additional radiation exposure for the scans, something that one should keep to a minimum. For many, benefits outweigh the risk. ...Read more
