Comparison of methods for determination of glomerular filtration rate: low and high-dose Tc-99m-DTPA renography, predicted creatinine clearance method, and plasma sample method
The gamma camera uptake method with
Tc-99m-DTPA (diethylenetriaminepentaacetic acid) is
a simple method for determination of glomerular
filtration rate (GFR), and is less time-consuming than
other methods, but its diagnostic accuracy is debated.
Gate’s method (low-dose; LD), the high-dose method
(HD), the predicted-clearance method, and the plasmaclearance
method with Tc-99m-DTPA are compared in
this study. We also performed GFR measurement and
diuretic renography simultaneously. Tc-99m DTPA
renography was performed in 36 patients aged 18–72
years with a wide range of renal function (serum
creatinine 1.37 ± 0.49mg/dl).GFR was determined by
four methods: the gamma camera uptake method with
low-dose Tc-99m DTPA (Gates, LD); the gamma
camera uptake method with high-dose Tc-99m DTPA
(HD); the predicted creatinine clearance method (Cockcroft–
Gualt, CG); and the plasma sample clearance
(PSC) method using a mono-exponential curve. The
PSC method was chosen as reference. The regression
equations for the CG, Gates (low-dose), and HD
methods against the PSC method were 28.68 + 0.80X
(r = 0.72; P value\0.0001, RMSE = 21.65 ml/min/
1.73 m2), 6.19 + 0.79X (r = 0.90; P value\0.0001,
RMSE = 10.64 ml/min/1.73 m2), and 6.53 + 0.88X
(r = 0.93; P value\0.0001, RMSE = 9.35 ml/min/
1.73 m2), respectively. In comparison with determination
of GFR by the PSC method, the CGmethod tended
to overestimate GFR while, perversely, the LD and HD
methods tended to underestimate GFR. The three
methods were in agreement with the PSC method but
the high-dose GFR method resulted in less error in
estimation of GFR. Furthermore, GFR measurement
and diuretic renography could be performed at the same
time when the high-dose method was used. Because of
the low cost and negligible radiation burden, this
method might be preferred for routine practice in
nuclear medicine
