Before a CT Scan, Many Should Take Drug to Protect Kidneys

Newswise — 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.

That “dye,” called contrast agent, is usually given intravenously before a CT scan, angiogram or other test. But the new study shows that taking an N-acetylcysteine tablet before receiving the contrast agent can protect patients — and that it works better than other medicines that have been proposed for the same purpose.
