    en.wikipedia.org/wiki/Contrast-induced_nephropathy

    European guidelines classify a pre-existing decreased kidney function to be a risk factor of contrast-induced nephropathy in the following cases: [5]. Estimated glomerular filtration rate (eGFR) < 45 ml/min/1.73 m 2 of body surface area before intra-arterial administration with first-pass renal exposure (not passing lungs or peripheral circulation before kidneys), or in the intensive care unit

    impaired kidney function is the major risk factor Nephrogenic systemic fibrosis is a rare syndrome that involves fibrosis of the skin, joints, eyes, and internal organs. NSF is caused by exposure to gadolinium in gadolinium-based MRI contrast agents (GBCAs) in patients with impaired kidney function.

    en.wikipedia.org/wiki/Iodinated_contrast

    If kidney impairment is found before administration of the contrast, metformin should be withheld for 48 hours following the procedure and until kidney function has returned to normal. [32] Contrast exposure may interfere with subsequent radioiodine treatment, causing unwanted delays in the management of thyroid cancer. [30]

  9. Gadodiamide - Wikipedia
