Currently is the largest medical society in Italy with over nine thousand members and provides the main framework for presenting and exchanging the scientific experience of different hospital-and university-based working group. At present SIRM is the national member of the European Society of Radiology with the largest number of both institutional and individual affiliated radiologist. Our Society manages its activity through two organising structures: study sections and regional groups that work together, representing the real scientific and professional core of the society. Each section has one president and four councillors and its aim is to promote the radiological advancement and also to organise the Continual Medical Education (ECM) for our members. Regional groups are based on the geographical division of our Country. The Society has two main seats: the first one, the Headquarters in Milan, and the other one House of Radiologic Area in Rome where E-learning, research and development take place. This venue hosts also inter-society meetings
