Nuclear medicine therapy is a medical treatment that uses radionuclides and the radiation they produce to treat diseases.



1. Definition
Nuclear Medicine Therapy refers to the use of radionuclides in the body can be highly selective in the characteristics of the diseased tissue, through the radiation emitted by radiopharma to kill diseased cells, so as to achieve the purpose of treating diseases. This treatment method has the advantages of strong killing effect on diseased tissues and small radiation damage to normal tissues.

2. Principle
The basic principle of nuclear medicine therapy is to use the metabolic characteristics of radionuclides in organisms to introduce radiopharma into the body and reach diseased tissues and organs. These radiopharmaceuticals gather in the diseased tissue and release rays to irradiate and destroy the diseased cells, so as to achieve the effect of treating diseases.



3. Scope of application
Nuclear medicine therapy is used in the treatment of a variety of diseases, including but not limited to the following aspects:

Tumor therapy: For certain malignant tumors, especially those that are not sensitive to conventional treatment, nuclear medicine therapy offers an effective means of treatment. For example, radioactive iodine (such as 131I) is used to treat hyperthyroidism and thyroid cancer, and radioactive strontium (such as 89Sr) is used to treat bone metastatic cancer.
Treatment of cardiovascular diseases: Nuclear medicine is also applied in the treatment of cardiovascular diseases, such as the use of radionuclides for myocardial perfusion imaging to evaluate the myocardial blood supply and provide evidence for the treatment of cardiovascular diseases such as coronary heart disease.
Treatment of other diseases: Nuclear medicine therapy can also be used for the treatment of many other diseases, such as the use of radiopharmaceutics to relieve intractable bone pain, the treatment of inoperable malignant pheochromocytoma.

4. Advantages
Precision therapy: Nuclear medicine therapy can accurately deliver radiopharmaceuticals to diseased tissue, reducing the damage to normal tissue.
Significant efficacy: For some difficult-to-cure diseases, nuclear medicine therapy provides an effective means of treatment that can significantly improve patients' symptoms and quality of life.
Non-invasive or minimally invasive: Compared with surgical treatment, nuclear medicine treatment has the characteristics of non-invasive or minimally invasive, reducing the patient's pain and recovery time.



5. Precautions
Safety: Although nuclear medicine therapy has many advantages, it is still necessary to pay attention to safety issues in the treatment process. Doctors need to strictly control the dose and exposure time of radiopharma to ensure the safety of patients and medical staff.

Individualized treatment: Nuclear medicine therapy needs to develop an individualized treatment plan according to the specific situation of the patient in order to achieve the best treatment effect.
Nuclear medicine therapy is a kind of medical treatment that uses radionuclides and the radiation produced by them to treat diseases. It has the advantages of precise treatment, remarkable curative effect, non-invasive or minimally invasive. It has been used in the treatment of many diseases, but the problems of safety and individualized treatment still need to be paid attention to.
