As for the Department of Nuclear Medicine, it is the department that utilizes nuclear medicine technology for diagnosis and treatment.
Commonly speaking, nuclear medicine contains two contents: 1, diagnosis. 2, treatment
In terms of diagnosis, it is divided into two parts, one is the use of blood specimens, the use of radioisotope-labeled drugs, specimens of a certain substance for qualitative or quantitative analysis, to determine the patient's body whether there is a certain substance or a certain substance, to indicate whether it may be suffering from a disease. have a certain disease. (For patients, blood is also drawn and then tested, only the way of testing is different from the ordinary laboratory). The second is to examine the patient with a large-scale instrument, usually SPECT/CT or PET/CT. (For patients, it is impossible to tell the difference between this machine and CT, MRI, but the essence is completely different) This test is more items, the same point is that before the examination are injected with some kind of short half-life radioisotope labeled drugs, the drug is generally in 24-48 hours completely metabolized (completely metabolized means that with normal people who did not have injections of the drug is roughly the same).
The treatment is now common to carry out three kinds of projects: 1, hyperthyroidism radionuclide treatment. 2, the treatment of bone metastases. 3, radioactive particle implantation on the treatment of malignant tumors. Of course, there are also other, but not many hospitals to carry out, the amount of patients is also relatively small.
If you read the above paragraph you will find that all carry out the project need to utilize radioisotopes, radioisotopes are also known as nuclides, so this technology is called nuclear medicine, the department is called nuclear medicine.
