Do we have set cutoffs for creatinine levels and if so what are they?

Although this will vary on the patient and the importance of the study general guidelines are that for creatinines under 1.7 we will use Omnipaque-350. For creatinines of 1.8-2.1 or so when the study is needed we use Visipaque-320. Please note that we will make certain to minimize the contrast volumes in patients with the use of saline flush or just smaller volumes of contrast. On select studies we can use as little as 60 ml of contrast. Remember that there is no threshold of contrast volume for inducing CIN but it is uncommon with volumes of 100 ml or less.
