Concordance between estimated glomerular filtration rate using equations and that measured using an imaging method.

Background: Guidelines recommend estimating glomerular filtration rate (GFR) using creatinine-based equations (CBE).

Aim: To evaluate the agreement between GFR measured using radionuclide imaging and estimated using creatinine-based equations.

Material And Methods: In 421 patients aged 54 ± 17 years (47% women) GFR was estimated using the MDRD-4, CKD-EPI and the body surface adjusted Cockroft Gault equation.
