It's a good idea to wear loose, comfortable clothes as you may be able to wear these during the scan During a CT scan, you're briefly exposed to ionizing radiation. The amount of radiation is greater than you would get during a plain X-ray because the CT scan gathers more-detailed information. The low doses of radiation used in CT scans have not been shown to cause long-term harm, although at much higher doses, there may be a small increase in your potential risk of cancer A CT scan of the head may be recommended for people with frequent migraines or headaches, in order to rule out other causes of the pain.

CT is an important tool in medical imaging and a sensitive method for diagnosing a wide range of conditions including cancer, heart and vascular disease, trauma and musculoskeletal disorders CT scan (computer tomography) and PET scan (positron emission tomography) are different but related imaging techniques. A PET scan uses nuclear medicine imaging to produce a three-dimensional picture of functional processes in the body. PET scans provide metabolic information and are increasingly read alongside CT or MRI (magnetic resonance imaging) scans, which provide anatomic information The number of CT scans required to give a cumulative dose of 50-60mGy depends on the type of CT scan, the age of the patient, and the scanner settings.
