What does ICM stand for in radiology contexts?

Explanation:
In radiology, ICM stands for iodinated contrast media. These are iodine-containing substances used to enhance X-ray-based imaging, especially CT and fluoroscopy. Iodine has a high atomic number, so it strongly absorbs X-rays, making blood vessels, organs, and lesions stand out from surrounding tissues. They’re typically given intravenously or intra-arterially to improve visualization. Modern practice usually uses nonionic, low-osmolality iodinated contrast for better tolerance. Other terms listed are either unrelated or too vague to be the standard meaning in radiology.
