Before A CT Scan Or Angiogram, Many People Should Take Inexpensive Drug To Protect Kidneys

ScienceDaily (Feb. 20, 2008) — As more and more Americans undergo CT scans and other medical imaging scans involving intense X-rays, a new study suggests that many of them should take a pre-scan drug that could protect their kidneys from damage. The inexpensive drug, called N-acetylcysteine, can prevent serious kidney damage that can be caused by the iodine-containing "dyes" that doctors use to enhance the quality of such scans.
