Assessing the patient's GFR (glomerular filtration rate) is important before performing an MRI scan on a patient with compromised renal function. This helps determine the patient's ability to filter out contrast agents used during the MRI procedure, which can cause further renal damage. NPO (nothing by mouth) for 24 hours is not required before an MRI scan, an IVU (intravenous urogram) or ultrasound study may not provide necessary information related to compromised renal function.
