”Interventional” refers to interventional radiology, which consists of two major components: diagnosis and treatment. It is the application of “non-surgical” methods to diagnose and treat diseases under the surveillance and guidance of X-ray, CT, MRI, B-ultrasound and other imaging equipment. “Interventional medicine is the third most important treatment technology based on high technology and characterized by the minimally invasive treatment. Interventional medicine is known as a beautiful flower in the garden of modern medicine, with a large scope of treatment, high treatment difficulty, and almost omnipotent in the human body. With the latest achievements of modern science and technology, it enables clinicians to precisely see the human body and, under the guidance of advanced imaging equipment, to accurately insert catheters into diseased organs of the human body for examination or treatment. It caters to the modern society’s demand for less traumatic and less painful treatment techniques, making the scope of surgery more and more limited and damaging to smaller and smaller tissues. More importantly, interventional medicine can solve many difficult problems that are beyond the reach of medical drugs and lost to surgery, such as advanced cancer, vascular embolism, and luminal stenosis.
