WebA method for 99m Tc-diethylenetriaminepentaacetate (DTPA) gamma-camera renography is presented. From each renogram, an uptake index (UI) proportional to the single-kidney glomerular filtration rate (SKGFR) is defined. If the proportionality factor between UI and SKGFR is the same in all patients, UI can be used as an accurate measure of SKGFR. WebDTPA è il secondo radiofarmaco renale più comunemente usato negli Stati Uniti, soprattutto perché è il meno costoso. Tc-99m-DTPA viene filtrato dal glomerulo e può essere utilizzato per misurare la velocità di filtrazione glomerulare. La frazione di estrazione di DTPA è di circa il 20%, inferiore alla metà di quella di MAG3.
