title: 99mTc-2,3-diaminopropionic acid complex as renal function agent: comparison of biological properties with 99mTc-DTPA and 131I-OIH.
abstract: The preparation, purification, biodistribution, blood disappearance kinetics and imaging characteristics of 99mTc-2,3-diamino propionic acid (99m-Tc-DAPA) is studied. The latter three studies were conducted on rabbits as the experimental animal and the data thus obtained were compared with 99mTc-diethylenetriaminepentaacetic acid (99mTc-DTPA) and 131I-orthoiodohippurate (131I-OIH) with a view to find a possible replacement of the latter radiopharmaceutical with a more convenient 99mTc based compound. Preliminary data indicates favourable results for 99mTc-2,3-diamino propionic acid which warrants further investigation.
