Question: What are the differences between an MRI, bone scan and CAT scan?
Answer: Magnetic resonance imaging, or MRI, produces computerized images of internal body tissues by using powerful magnets and radio waves. A healthy tissue returns a slightly different signal than abnormal tissue.
Computed axial tomography, or CT or CAT scan, uses X-rays to quickly create a 3-D image of the body. Sometimes a dye is used to highlight specific areas inside the body.
A bone scan detects abnormalities involving bones. Bone-seeking radioactive material is injected into a vein and travels through the bloodstream. As the material wears away, it emits radiation that is identified by a camera that scans the body.
