[Functional parameters calculated by 99mTc-MAG3 in transplanted kidney].
A newly developed 99mTc-labeled renal tubular agent, 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) was evaluated and compared with 99mTc-DTPA and 123I-OIH in 10 patients with a transplanted kidney. Renal uptake of MAG3 correlated well with both DTPA and OIH; however, these uptake values of MAG3 were lower than those of OIH and higher than those of DTPA. Renogram parameters also correlated well with each other, but excretion of MAG3 was slower than that of OIH and faster than that of DTPA. The bladder to kidney ratio of MAG3 also correlated well, but these ratios of MAG3 were lower than those of OIH and higher than those of DTPA. In conclusion, MAG3 is a promising agent for evaluating the function of transplanted kidney.
