Technetium (99mTc) pentetic acid

Technetium (99mTc) pentetic acid is a radiopharmaceutical compound used primarily in nuclear medicine for diagnostic imaging. It consists of technetium-99m, a radioisotope of technetium that emits gamma radiation, combined with pentetic acid (also known as diethylenetriaminepentaacetic acid, or DTPA), which acts as a chelating agent.
