Figure 1: European Training Curriculum (ETC) of the European Society of Radiology (ESR). The ESR offers a training curriculum as a blueprint, which is filled with content by the European subspeciality societies. Level I and II are equivalent to speciality training and are graduated with the European Diploma in Radiology (EDiR). Subsequently, the subspeciality societies can offer a formal graduation of a LEVEL III subspeciality. Regarding the European Society of Emergency Radiology (ESER), this will be implemented with a European Diploma in Emergency Radiology (EDER). A comparable development can be observed in other national and supranational medical (sub-)speciality societies.
