Technetium-99m (Tc-99m)

Technetium-99m (Tc-99m) is a radioactive isotope commonly used in medical imaging. It emits a small amount of radiation that allows doctors to visualize and examine organs, tissues, and blood flow inside the body. Because it quickly travels to specific areas and decays fast, it minimizes radiation exposure while providing detailed images. Tc-99m is often attached to various compounds that target particular organs, making it a versatile and essential tool for diagnosing conditions like cancer, heart disease, and infections. Its safety, effectiveness, and precise imaging capabilities make it a cornerstone of nuclear medicine.
