Like X-rays and PET scans, CT scans use ionizing radiation, which can damage DNA and cause cancer. Two other imaging technologies, MRI scans and ultrasound, do not use radiation. CTs are used for a plethora of reasons, among them finding kidney stones, evaluating chest pain and detecting tumors or other abnormalities.
