Simply put, we’re overtested and over-radiated. This adds $20 billion a year in unnecessary costs1 — costs we ultimately end up paying for in our health insurance premiums. But duplicate radiology tests can also result in potentially harmful radiation exposure. Consider that a single CT scan can expose a patient to as much as 1,000 times more radiation than a basic X-ray.2 Medical radiation is estimated to cause up to 2 percent of cancers.3 And though many tests undoubtedly prove to be beneficial, others, such as CT scans for migraines, do not. Such scans seldom show the source of headaches or help patients better manage symptoms.4
