Functional MR of the kidney.
A bolus injection of Gadopentetate Dimeglumine with dynamic gradient echo MR imaging has allowed for the visualization of normal and abnormal renal function. Following an injection of gadopentetate dimeglumine, NMR T1 relaxation times obtained on serial collections of serum and urine at timed intervals were used to derive the glomerular filtration rate. The merger of dynamic contrast-enhanced MRI with an in vitro NMR-derived GFR provides for assessment of renal function without the use of radioactive agents.
