Final answer:
A bone scan uses a radioactive dye to produce an image of the bones.
Step-by-step explanation:
The diagnostic image that uses a radioactive dye to produce an image is a bone scan. In a bone scan, a small amount of radioactive dye, also called a radiopharmaceutical or radiotracer, is injected into a vein in the patient's arm. The dye then circulates through the bloodstream and is absorbed by the bones. A special camera detects the radioactive emissions from the dye and creates an image of the bones, showing areas of increased or decreased uptake of the dye.
