- FIGURE 1.
The 4 stages of radionuclide-based GFR studies.
- FIGURE 2.
Two- and 3-compartment models with respective rate constants, kij. K10 is taken to be GFR clearance. Two-compartment model views compartment 1 as intravascular volume and compartment 2 as extravascular volume. Compartment 3 is considered to be present in patients with known third fluid compartments.

Example of 9-sample (5, 10, 20, 60, 120, 180, 240, 360, and 480 min) plasma clearance for a given dose of 99mTc-DTPA. (A) Plot of plasma sample counting rate vs. time (black dots) with fitted biexponential curve. (B) Part A with individual early and late exponential curves. (C) Linear fits for natural logarithm of early and late exponentials.
