1 DTPA / MAG3 / DMSA

---

99mTc-DTPA - cleared by glomerular filtration

99mTc-MAG3 - cleared by glomerular filtration and tubular excretion - more useful if renal function is impaired or in children.

99mTc-DMSA - accumulates in renal tubules, gives map of functioning renal tissue, useful in cortical masses or scarring.

0 Radiation dose - Units

---

Radiation dose is quantified using both the conventional units system and the international system of units, or SI.

• “Radiation exposure” is measured in roentgens (R) for conventional units or coulombs per kilogram (C/kg) in SI units.

• “Absorbed dose” is measured in rads (rad) for conventional units or grays (Gy) for SI units.

• “Equivalent dose” is measured in rems in conventional units or sieverts (Sv) for SI units.

• “Effective dose” is measured in effective dose equivalents (Sv—1977 tissue-weighting factors), or sieverts (Sv) for SI units.
