How do you protect your kidneys from contrast dye?
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.
Can contrast dye hurt your kidneys?

How do you prevent renal failure with contrast?
The main prophylactic strategies comprise: reduction of modifiable risk factors (anaemia, hypotension, use of nephrotoxic drugs), reduction of CM exposure and peri-procedural oral or intravenous hydration (see Figure 1).
When should you not use IV contrast?

How does contrast media affect kidney function?
