Interventional medicine (interventional radiology) is an emerging discipline that has developed rapidly in the past 20 years, integrating medical imaging and clinical therapeutics, involving the diagnosis and treatment of many systems of human digestive, respiratory, cardiovascular, neurological, urological and skeletal diseases. It is simple, safe, effective, less invasive, and has fewer complications. It is characterized by the adoption of percutaneous puncture and cannulation under the guidance of imaging methods, angiography, pathology, physiology, cytology, bacteriology, biochemistry and other examination data, drug infusion, vascular embolization or dilatation and shaping and body cavity drainage, and other “non-surgical” methods to diagnose and treat a variety of diseases. Interventional radiology is the product of the combination of clinical medicine and medical imaging, and its safe, effective, less invasive and less complications are in line with the future development direction of medicine.
