Nuclear Medicine is a specialized field of medicine that uses small amounts of radioactive materials, known as radiopharmaceuticals, to diagnose and treat various diseases. This technique allows healthcare professionals to visualize the function of organs and tissues, providing valuable information that traditional imaging methods may not reveal. In addition to diagnostics, Nuclear Medicine plays a crucial role in treatment, particularly for conditions like cancer. By targeting specific areas of the body with radiation, it can effectively destroy malignant cells while minimizing damage to surrounding healthy tissue. This dual capability makes Nuclear Medicine an essential tool in modern healthcare.
