Is the radiation used in X-rays, CT scans, and Nuclear Medicine tests harmful?
X-ray and CT exams use radiation to make images of the body. X-rays are safe and effective for people of all ages. Patients have an X-ray or CT scan only when their condition warrants more information than a physical exam can provide. Our radiologists take great care to use the lowest radiation dose possible to produce the best images for diagnosis. The dose of radioactive material given for nuclear medicine tests is very small, and there are no known long-term adverse effects. If you are pregnant or suspect you may be pregnant, inform your doctor before having an X-ray or nuclear medicine test. In general, exposure to radiation during pregnancy should be kept to a minimum. Your doctor may decide to use another imaging test such as ultrasound.
