    ALL pts who will receive IV contrast should be prehydrated, in order to PREVENT any CIN (Contrast-induced nephropathy).

    Check out the articles below (obtained by doing a Google search using the words "contrast prehydration prevent nephropathy"):

    Thank you for the articles I practice in a free standing CT/MRI clinic but the info helped prove my point.

    Keep in mind IV contrast is also a diuretic so it is important to hydrate before and after the injection. In a patient without renal insuficency I am comfortable with PO hydration rather than IV.

    We recently have been checking the GFR (glomerular filtration rate) in addition to the creatinine. If your lab is not reporting this you can go to www.nkdep.nih.gov and use the calculator. If the GFR is <60 the Rads will decide on before or after. At present they all want something different, but we are working on protocols.

    Creatinine over 1.6 we administer 1/2 of the contrast dose and hydrate afterwards.

    We do use Visipaque (iodixanol) for creat >1.5 AND eGFR <60. All other exams we use Omnipaque 350 (iohexol). This is for Cath Lab use.

    IR uses Visipaque exclusively.
