- Women with any known renal disease - if an MRI is deemed necessary, a serum creatine
will be checked prior to injection of contrast. Using the National Kidney Foundation
recommendations, a GFR or glomerular filtration rate greater than 60 may safely
receive intravenous gadolinium-based MRI contrast. Those individuals with a GFR >30
and <60 can receive the contrast but at a reduced dose (typically half). Those with a
GFR <30 will not receive MRI contrast and will not undergo the exam. Breast MRI must
be done with contrast if evaluating for cancer. Several factors can affect the GFR
such as age, body size, creatinine, renal status and will be calculated from the
blood drawn. GFR is the final determinant and a creatinine greater than 1.6 usually
has a GFR that precludes a Breast MRI with contrast. The final determinant will be
the GFR.
