Multiple Choice

What is the gold standard radiopharmaceutical for measuring Glomerular Filtration Rate (GFR)?

The ability to assess GFR with a radiopharmaceutical hinges on using a tracer that is filtered by the glomerulus and undergoes little to no tubular reabsorption or secretion, so its clearance mirrors true GFR. Tc-99m DTPA fits this need because it is filtered by the glomerulus and excreted into urine with minimal tubular processing, making its plasma clearance a good estimate of GFR. In contrast, Tc-99m MAG3 is largely secreted by the proximal tubules and is used to estimate renal plasma flow rather than GFR; Tc-99m DMSA concentrates in renal cortex for structural imaging and scar assessment rather than filtration; and 18F-FDG is a metabolic tracer used for PET imaging, not for GFR measurement. Therefore, Tc-99m DTPA is the best choice for measuring GFR.

This is one of multiple questions in the full bank.

    Decent resource, but a few questions seemed more tricky than they should be for a study session. I’d like a few more foundational reviews in the explanations. Still, the randomization and flash cards are useful, and I’ll keep using it to shore up gaps.

    Randomized format forces you to cover a broad range of topics quickly. Some questions felt a tad niche, but the explanations helped me understand why. Overall, a strong tool for exam readiness, especially with the flash cards and quick recaps before bed.
