In the past, when you went to the hospital, you might have gone to the Department of Medicine, Surgery, and the Department of Five Gases ……, but you might not have heard of “Interventional Radiology”. Interventional Radiology, collectively known internationally as Interventional Radiology, is a rapidly developing fringe discipline that integrates medical imaging and clinical therapeutics over the past 20 years, and is a product of the close integration of clinical medicine and medical imaging. Under the guidance of various medical imaging devices, it integrates diagnostic imaging and minimally invasive treatment, using some special puncture needles, catheters, guidewires, stents and other minimally invasive devices to perform angiography, collect pathological, physiological, cytological and biochemical examination data, perform drug perfusion, vascular embolization or dilatation, and body lumen drainage on a series of lesions such as tumors and vascular stenosis. “Non-surgical” methods are used to diagnose and treat a variety of diseases. We can diagnose and treat almost all diseases of the human body, including digestive, respiratory, cardiovascular, neurological, urological, and skeletal systems. Its distinctive features are simplicity, safety, effectiveness, minimally invasive and few complications. Interventional therapy not only relies on the theoretical foundation of traditional clinical diagnosis and imaging, but also creatively expands the disciplinary fields of diagnosis and imaging, becoming a new third clinical discipline between traditional internal medicine and surgery, belonging to an emerging fringe discipline, and increasingly developing with the development of clinical medicine and imaging. Interventional therapeutics includes a series of minimally invasive diagnostic and therapeutic techniques, creating a new field of treatment and saving lives. Its greatest advantages are high efficacy, less trauma, less pain, accurate diagnosis and treatment, fewer complications, lower costs, and fast, easy and efficient. It has been widely recognized by the medical community and patients as a minimally invasive interventional technique that can treat many diseases that originally required surgical treatment.
