Radiological diagnosis and treatment refers to the activities of clinical medical diagnosis, treatment and health examination by using radioisotopes and radiation devices. According to the risk of diagnosis and treatment and the difficulty of technology, it can be divided into four categories: radiotherapy, nuclear medicine, interventional radiology and X-ray image diagnosis. Medical institutions must obtain the Permit for Radiological Diagnosis and Treatment issued by the administrative department of health before they can carry out the corresponding work of radiological diagnosis and treatment.
Radiotherapy: refers to the technology that uses the biological effects of ionizing radiation to treat diseases such as tumors. Such as stereotactic (X-knife, γ-knife) therapy, cobalt -60 machine therapy, electron linear accelerator, deep X-ray therapy, proton and other heavy particle therapy, afterloading therapy, application therapy and other radiotherapy projects.
Nuclear medicine: refers to the technology of using radioisotopes to diagnose or treat diseases or conduct medical research. Such as PET imaging diagnosis, SPECT imaging diagnosis, gamma camera imaging diagnosis, bone mineral density measurement, seed implantation therapy, radiopharmaceutical therapy and other nuclear medicine diagnosis and treatment projects.
Interventional radiology: refers to the technique of aspiration, injection and drainage by percutaneous puncture or catheter introduction under the monitoring and guidance of medical imaging system, or molding, perfusion and embolization of lumens and blood vessels to diagnose and treat diseases. Such as DSA interventional radiology diagnosis and treatment, other imaging equipment interventional radiology diagnosis and treatment and so on.
