Ydinmedisiinin

Ydinmedisiini, also known as nuclear medicine, is a medical specialty that uses radioactive substances, called radiopharmaceuticals, to diagnose and treat disease. These substances are introduced into the body, either by injection, inhalation, or swallowing, and they travel to specific organs or tissues. As the radiopharmaceuticals decay, they emit radiation that can be detected by special imaging equipment, such as a gamma camera or PET scanner. This allows physicians to visualize the function of organs and tissues, identify abnormalities, and monitor the effectiveness of treatments.

The diagnostic applications of nuclear medicine are diverse. For example, bone scans can detect fractures or the spread of cancer to bones. Thyroid scans help evaluate thyroid gland function. Heart imaging can assess blood flow to the heart muscle and detect damage. Brain imaging can aid in the diagnosis of Alzheimer's disease, Parkinson's disease, and strokes. Positron Emission Tomography (PET) scans, a type of nuclear medicine imaging, are particularly useful in oncology for detecting cancer, staging disease, and assessing treatment response.

In addition to diagnosis, nuclear medicine also plays a significant role in therapy. Certain radiopharmaceuticals are designed to target and destroy diseased cells, particularly cancer cells. For instance, radioactive iodine is used to treat thyroid cancer and hyperthyroidism. Radiotherapy using radioactive isotopes can also be employed for other types of cancer. The use of radiopharmaceuticals in therapy is carefully controlled to minimize exposure to healthy tissues. Nuclear medicine requires specialized training for physicians and technicians, and its procedures are conducted under strict safety protocols.
