Yes. If you would like to order a CT scan with IV contrast, your subject must have recent (within the last 3 months) BUN and creatinine blood test results available. If you would like to order an MRI scan with IV contrast, your subject must at least have a recent (within the last 3 months) creatinine result available and preferably (although not strictly required) a recent GFR result as well. All scans involving IV contrast require you to complete the Contrast Screening Information page while filling out the computerized order. The only exception to this is for pediatric patients.

The use of IV contrast is subject to approval by an attending radiologist. If your subject's lab results or questionnaire answers are below the Department of Radiology's safety thresholds, the reviewing radiologist may refuse the contrast portion of the scan, so it is best to have these results available before your subject arrives for his/her scan if possible. Please consult with the HIRO or an imaging manager if you have any questions or issues.
