Brain CT scan with sinus CT scan
CT (computerized tomography) scans are a type of imaging similar to x-rays. They take a series of pictures of the inside of the body. A CT scan of the brain is helpful for doctors to evaluate what might be causing severe headaches or other problems. A CT scan of the sinuses can determine if a patient has a sinus infection. If only the brain or only the sinus CT scan is needed for diagnosis, only one test should be performed. This will minimize radiation exposure to the patient.
