Nuclear medicine is a radiology subspecialty that applies radioisotopes in the diagnosis and treatment of disease.
- DIAGNOSIS: Utilizing radiation emitted from a patient’s body when a radiopharmaceutical is given intravenously or orally. The nuclear medicine images are obtained by the nuclear detectors (SPECT/CT or PET/CT), unlike X-ray or CT scan where the image is formed by an external radiation passing through the body.SPECT or PET scan fusing with low-dose CT scan displays the metabolism and anatomical structure of tumor or organs in a set of images simultaneously, which is one of the most effective imaging techniques today in the diagnosis, differentiation, and determining whether, where and how much degree the tumor has spread within the body. It is not only used in oncology, but also in diagnosis of infection site, neurological diseases, e.g. epilepsy, Alzheimer’s disease, and coronary heart disease in a special occasion.
- TREATMENT: Using specific radiopharmaceuticals to treat a benign or malignant disease, such as, hyperthyroidism, thyroid cancer, neuroblastoma, neuroendocrine tumor. Nuclear medicine image also helps planning of radiation therapy.
- CHECK TREATMENT RESPONSE: Assessing the treatment response by imaging the tumor site and whole body.
