Lead poisoning is always detectable from an x-ray.

Explanation:
Lead poisoning is diagnosed by measuring the level of lead in the blood, not by imaging. Imaging studies can’t reliably reveal the poisoning in all cases. In some chronic exposures, X-rays may show dense metaphyseal lines called lead lines, but these are not always present and don’t quantify how much lead is in the body. MRI isn’t used to diagnose lead poisoning, and normal imaging does not rule it out. So, it’s incorrect to say lead poisoning is always detectable on an X-ray.
