Rapid determination of glomerular filtration rate in infants using Tc-99m DTPA.
Glomerular filtration rate obtained by using Tc-99m DTPA was compared with that obtained from Schwartz's formula using serum creatinine and length in 21 infants (age range, 3 to 348 days). The GFR (mean +/- SD) obtained by Tc-99m DTPA was 76 +/- 37 ml/min per 1.73m2 and by the Schwartz formula was 83 +/- 49 ml/min per 1.73m2. GFR by Tc-99m DTPA method overestimated GFR by 3.6% compared to the Schwartz method. The imaging technique and the advantages are discussed.
