l am considering an MRI to determine the cause of my lower back pain. My eGFR is usually around 50. You have often warned about having contrast dye injected in connection with this procedure. I wonder if there might be an alternative contrast agent with which you are familiar? If not does a single application lead to significant kidney damage?

A magnetic resonance imaging (MRI) scan used contact agents such as gadolinium, which is safe for kidney patients with an estimated glomerular filtration rate (eGFR) of 50 milliliters per minute per 1.73 meters squared.  I recommend avoiding MRI contrast agents for patients with an eGFR less than 30.  In cases where the eGFR is less than 30, an uncommon skin reaction to the contrast may occur.  Hence, I believe that a MRI scan should be safe for you if your physician believes this is indicated.
