"Iodinated contrast agents and acute kidney injury"

Iodinated contrast agents are dyes used in medical imaging, like CT scans, to improve picture clarity. Sometimes, these dyes can cause a temporary decline in kidney function, known as acute kidney injury, especially in individuals with pre-existing kidney problems or other risk factors. This happens because the contrast may reduce blood flow to the kidneys or cause direct toxicity. However, such cases are usually rare, and doctors take precautions, like hydration and checking kidney health beforehand, to minimize risks and ensure safe imaging procedures.
