99mTc DTPA vs. 51Cr EDTA for glomerular filtration rate measurement: is there a systematic difference?

Conclusion There is a small systematic difference between GFR measured with 99mTc DTPA and 51Cr EDTA using abbreviated techniques, which is removed when GFR is calculated by full characterisation of the plasma clearance curve. The difference is not clinically significant in the context of intra-patient variability of GFR measurement.
