Description

technical field

[0001] The invention relates to a magnetic resonance imaging-detectable liquid embolism composition used in the field of medical interventional therapy, which is mainly used for embolization therapy of vascular malformation, hemangioma, liver cancer, kidney cancer and lung cancer. Background technique

[0002] Interventional therapy was developed in the 1970s. It is an interdisciplinary subject that combines medical imaging and clinical therapy. It has the characteristics of minimally invasive, fast recovery, and good curative effect. It has opened up new possibilities for previously incurable or intractable diseases. way of treatment. At present, it has become the three most important therapeutic disciplines along with internal medicine and surgery. Interventional embolization therapy is an important part of interventional therapy. With the guidance of imaging equipment, the doctor injects embolic material through a precise catheter and blocks local blood v...
