Nuclear medicine examinations offer a unique perspective on the human body because they not only visualize the structure of tissues and organs, but also make their physiological processes visible. In contrast to other imaging procedures, which mainly depict anatomy, nuclear medicine procedures focus on the function of tissues and organs. On this basis, we can detect diseases at an early stage, even before structural changes become visible. Modern nuclear medicine procedures, such as those we use in our practice, use only small amounts of radioactive substances, which leads to a comparatively low radiation exposure for the patient. The use of radioisotopes with a short half-life also minimizes the risk of long-term radiation damage.
