CT Policy Regarding Contrast Induced Nephropathy

If the departmental outpatient questionnaire raises the possibility of occult renal impairment,  then a POC Creatinine test will be performed at the time of the contrast enhanced CT study if no recent value (48 hours for in-pts, 6 weeks for out-pts) is available in EPIC. 

If eGFR value is greater than 30 the patient can receive IV iodinated contrast. If eGFR is less than 30 the case will need approval by the radiologist before IV contrast is used to minimize risk of contrast related AKI.

Please refer to contrast policy for full details:
