INTRODUCTIONrnInterventional radiology (IR) is a clinical specialty providing minimally invasive image?guided diagnosis and treatment of diseases in various organ systems.[1] Since Charles Dotter performed the first balloon angioplasty on patients with stenosis of the superficial femoral artery in 1964, IR has been applied in numerous aspects of mod medicine.[2] However, the development of IR also presents many problems such as the relationship with other disciplines and turf wars.[3,4] These problems puzzle many interventionists, and no solution has been proven to be applicable to every country.
