DTPA
DTPA
DTPA (pronounced dee-tee-pee-ay), also known as Diethylenetriaminepentaacetic acid, is a compound often used in medicine for its chelating properties.
Pronunciation
DTPA is pronounced as "dee-tee-pee-ay".
Etymology
The term DTPA is an acronym derived from the full chemical name, Diethylenetriaminepentaacetic acid. The name itself describes the chemical structure of the compound: "Di" means two, "ethylene" refers to the two carbon atoms, "tri" means three, "amine" refers to the nitrogen-containing functional group, and "pentaacetic acid" refers to the five acetic acid groups attached.
Usage in Medicine
In medicine, DTPA is primarily used as a chelating agent. It has the ability to bind to metals in the body, which can then be excreted in urine. This makes it useful in treating cases of heavy metal poisoning, such as with plutonium, americium, or curium.
DTPA is also used in radiology as a contrast agent. It can be radiolabeled with technetium-99m and used in renal scintigraphy, a type of medical imaging that evaluates the function and anatomy of the kidneys.
