Morphology
The phrase is directly compositional: 'contrast' (difference in visual/brightness terms) + 'material' (a substance) yields 'a substance that produces or enhances contrast.' A B1 learner who knows both words can infer it refers to a substance used to create contrast in imaging, even if the technical detail about x-rays is specialized.
Etymology
The term contrast material comes from the simple image of adding a special material that makes parts of the body stand out on a scan, like using a highlighter on a page. That's why it means 'a substance given during an x-ray or scan to make organs or blood vessels easy to see'.
