    摘要: This disclosure relates to the methods of imaging the kidneys and measuring renal function using the renal tracer 99mTc(CO)3(NTA) (technetium-99m tricarbonyl-nitrilotriacetic acid). The disclosure encompasses methods of imaging the kidneys and measuring effective renal plasma flow (ERPF) in an animal or human subject using renal scintigraphy, comprising administering to an animal or human subject an amount of a renal tracer, wherein the renal tracer comprises 99mTc-(CO)3(NTA). Another aspect of the disclosure are methods of measuring effective renal plasma flow in an animal or human subject, comprising administering to an animal or human subject an amount of a renal tracer, wherein the renal tracer comprises 99mTc-(CO)3(NTA), isolating a series of plasma samples from the animal or human subject after administering the renal tracer and quantitatively detecting the amount of the renal tracer in the biological samples.

The disclosure encompasses methods of imaging the kidneys and measuring effective renal plasma flow (ERPF) in an animal or human subject using renal scintigraphy, comprising administering to an animal or human subject an amount of a renal tracer, wherein the renal tracer comprises 99mTc—(CO)3(NTA). Another aspect of the disclosure are methods of measuring effective renal plasma flow in an animal or human subject, comprising administering to an animal or human subject an amount of a renal tracer, wherein the renal tracer comprises 99mTc—(CO)3(NTA), isolating a series of plasma samples from the animal or human subject after administering the renal tracer and quantitatively detecting the amount of the renal tracer in the biological samples.

    摘要: The present invention relates to novel metal chelates, exemplified as technetium-99m or rhenium chelates, and to the process of preparing such metal chelates from corresponding ligands. These ligands and their corresponding metal chelates are synthesized to have a cysteinylethylene (EC) structure, a monothiourea (MTU) structure, or a dithiourea (DTU) structure. The present invention further relates to a pharmaceutical composition comprising a metal chelate, for example, a .sup.99m Tc-chelate, to the use of the composition for renal imaging and examination of renal function, and to a kit for preparing such a composition prior to use.
