OpenExamPrep
The European Diploma in Radiology (EDiR) is a European certification from the European Board of Radiology (EBR/ESR) for radiologists and final-year residents. It is fully computer-based with three 90-minute parts: Multiple Response Questions (MRQs), Short Cases, and the Clinically Oriented Reasoning Evaluation (CORE). MRQ items may have more than one correct answer, and the written weighted score is 70% MRQs plus 30% Short Cases. There is no fixed pass percentage; the pass mark is Mean minus one Standard Deviation per session (around 53% written and 58% CORE), and each part must be passed. The fee is EUR 500 for ESR members. This 100-question bank gives single-best-answer practice across the EDiR general-radiology knowledge base.

About the EDiR Exam
The European Diploma in Radiology (EDiR) is a pan-European certification awarded by the European Board of Radiology (EBR) on behalf of the European Society of Radiology (ESR). It tests knowledge, skills and competence in general radiology, including anatomy, pathophysiology, imaging procedures, physics and management, based on the European Training Curriculum for Radiology, Levels I-II. The fully computer-based examination has three 90-minute parts: Multiple Response Questions (MRQs), in which items may have more than one correct option; Short Cases (SCs), which are image-based; and the Clinically Oriented Reasoning Evaluation (CORE), which uses practically oriented cases with a DICOM viewer and replaced the former oral examination in 2016. Candidates must be at least in their fifth year of national radiology training and ESR members, and must pass each part separately.
Exam sponsor: European Board of Radiology (EBR), an initiative of the European Society of Radiology (ESR).. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
Three computer-based parts: Multiple Response Questions (MRQs, knowledge), Short Cases (image-based), and the Clinically Oriented Reasoning Evaluation (CORE, practically oriented cases with a DICOM viewer). The written weighted score combines 70% MRQs and 30% Short Cases.
Time Limit
Each part is 90 minutes, for three timed sessions on the examination day.
Passing Score
No fixed percentage. The pass mark per session is Mean minus one Standard Deviation, and candidates must pass each part. Recent pass marks are approximately 53% for the written weighted score and approximately 58% for CORE.
Exam / Certification Fees
EUR 500 for ESR full members and ESR members in training.
Exam sponsor websiteFees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.
Our practice resources: topics covered
We aim to reflect publicly available exam outlines and topic information in our study resources. Coverage, format, and difficulty may differ from the actual exam, and we cannot guarantee that every detail is accurate or current. Confirm exam requirements, fees, and policies with the official exam sponsor.

Thoracic and Cardiovascular Radiology
Chest radiography and CT, pulmonary, mediastinal and pleural disease, pulmonary embolism, plus cardiac and vascular imaging including CT and MR angiography.
Abdominal and Genitourinary Radiology
Imaging of the bowel, liver, pancreas, biliary tree, spleen, kidneys, urinary tract and pelvis, including acute abdomen and oncologic staging principles.
Musculoskeletal and Neuroradiology
Fracture and arthropathy patterns, bone and soft-tissue tumours, plus brain, head and neck and spine imaging including stroke, haemorrhage and demyelination.
Breast and Paediatric Radiology
Mammography, breast ultrasound and MRI with BI-RADS, and paediatric imaging principles including dose minimisation, congenital conditions and age-specific pathology.

Frequently Asked Questions
What is the EDiR and who awards it?
The European Diploma in Radiology (EDiR) is a pan-European certification in general radiology awarded by the European Board of Radiology (EBR), an initiative of the European Society of Radiology (ESR).
What parts make up the EDiR examination?
There are three computer-based parts, each 90 minutes: Multiple Response Questions (MRQs), Short Cases (SCs) and the Clinically Oriented Reasoning Evaluation (CORE). Candidates must pass each part.
Are EDiR questions single-best-answer?
The MRQ section uses multiple-response items, meaning a question can have more than one correct option to mark. The Short Cases and CORE sections are image-based and practically oriented rather than simple single-best-answer.
What score do I need to pass the EDiR?
There is no fixed percentage. The pass mark is set per session as the Mean minus one Standard Deviation, and each part must be passed. Recent pass marks are roughly 53% for the written weighted score and 58% for CORE.
Who is eligible to sit the EDiR?
Candidates must be at least in their fifth year of national radiology training (or an equivalent four-plus years of training and supervised practice) and be ESR members in the examination year.
Are these official EBR practice questions?
No. These are original OpenExamPrep questions modelled on the EDiR general-radiology knowledge base. The EBR provides official sample tests, the EDiR Blueprint and other resources separately.
