What Student Need to Know about Importance of Nuclear medicine In RadioDiagnosis.

Nuclear medicine is a medical specialty that uses radioactive tracers (radiopharmaceuticals) to assess bodily functions and to diagnose and treat disease. Specially designed cameras allow doctors to track the path of these radioactive tracers. Single Photon Emission Computed Tomography or SPECT and Positron Emission Tomography or PET scans are the two most common imaging modalities in nuclear medicine. One example is radioactive iodine (I-131). It has been used for over 50 years to treat thyroid cancer and hyperthyroidism, or an overactive thyroid. Now, it is also used to treat non-Hodgkin lymphoma and bone pain from some kinds of cancer. Iodine-131 (I-131) targeted radionuclide therapy (TRT) introduces radioactive iodine into the body. As the thyroid cells or cancer cells absorb this substance, it kills them. I-131 can be given as capsules or in liquid form. What are radioactive tracers? Radioactive tracers are made up of carrier molecules that are bonded tightly to a radioactive atom. Th
