Nuclear Medicine & Molecular Imaging

Nuclear medicine operates by administering radioactive isotopes to the patient’s body and detecting the radiation emitted by these isotopes. These radioactive substances are typically administered to the body through injection, oral intake, or inhalation. Radioactive isotopes can concentrate in organs or target tissues within the body. Then, using a specialized detector, the radiation is detected. The data obtained is analyzed by computers and used for understanding organ functioning and disease diagnosis.

Molecular imaging, on the other hand, is a technique used to visualize molecular processes and cellular-level changes within the body. These imaging techniques generally include technologies such as magnetic resonance imaging (MRI), positron emission tomography (PET), single-photon emission computed tomography (SPECT), and computed tomography (CT). These methods can detect molecular-level changes and play a significant role in early disease diagnosis, treatment monitoring, and drug discovery.

Nuclear medicine and molecular imaging serve as effective diagnostic tools in various diseases. For example, they are commonly used in the evaluation of cancer diagnosis and staging, diagnosis of heart diseases, and monitoring treatment response. Additionally, they can be utilized in various other areas, including brain functions, bone metabolism, and thyroid gland functioning.

However, the use of nuclear medicine and molecular imaging techniques should be approached with caution due to their involvement with radiation. Experts consider the benefits and risks while taking safety measures to minimize radiation exposure for patients. The utilization of these techniques should be guided by appropriately trained and experienced healthcare professionals.
