The R.R.A. may provide initial observations but cannot render the final, official interpretation of imaging studies The R.R.A. may render final interpretations on plain radiographs but not on cross-sectional imaging The R.R.A. practices fully independently once certified by ARRT The R.R.A. may only perform procedures on patients under age 18 under radiologist supervision

Question 2

A 68-year-old patient scheduled for a fluoroscopic esophagram has a serum creatinine of 2.8 mg/dL and an eGFR of 24 mL/min/1.73 m². The study will use oral barium sulfate only. Based on the ACR Manual on Contrast Media, what is the correct action?

Proceed with the barium esophagram; renal function is not a contraindication to oral barium Cancel the study because the eGFR is below 30 Administer IV normal saline at 100 mL/hr for 12 hours before the study Substitute iodinated water-soluble contrast (Gastrografin) for the barium

Correct Answer:

Proceed with the barium esophagram; renal function is not a contraindication to oral barium
