Miss Lodestone: "Doctor, our new MRI exposes patients to 75% less X-ray radiation than the previous generation of scanners."
Dr. Grumpy: "MRI doesn't use X-rays. It uses magnetism."
Miss Lodestone: "Correct! Now that modern MRI no longer needs X-rays, we've been able to reduce the amount patients are exposed to in a scan."
Dr. Grumpy: "MRI has never used X-rays. Different physics."
Miss Lodestone: "That's why the new scanners have allowed us to bring it down by 75%!"
