The daily practice of radiologists has evolved and radiologists are increasingly being directly involved with patient care and treatment. Consequently, radiologists have become a part of the therapeutic team available to patients. This active role, in hospital based or out-patient practices, does not only have an impact on the radiologist's professional activities. New liabilities related to interventional procedures or treatments are now added to already existing professional liability from diagnostic activities. Therefore, musculoskeletal radiologists performing interventional procedures must be aware and familiar with their obligations towards patients, including the requirement to provide adequate information to patients and documenting that informed consent was obtained.
