The European Diploma in Radiology (EDiR) is the European Board of Radiology's general radiology diploma, endorsed by the ESR and the UEMS. It is a one-day computer-based exam with 78 Multiple Response Questions (95 minutes), 24 Short Cases (90 minutes) and 10 CORE cases (90 minutes). Part 1 weights MRQs 70% and Short Cases 30%; Part 2 is CORE. Pass marks are the mean minus one standard deviation within fixed bounds (about 53% and 58% in practice), there is no negative marking, and candidates must pass each part. The fee is EUR 500 for ESR full and in-training members or EUR 1,100 for corresponding members.

Sample EDiR Practice Questions

Try these sample questions to review concepts for the EDiR exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 182+ question experience with AI tutoring.

1A 2-year-old suddenly coughs while eating nuts. An expiratory chest radiograph shows persistent right-lung hyperlucency and expansion while the left lung decreases in volume. Which diagnosis best explains the asymmetry?

A.Right lower-lobe pneumonia with alveolar filling

B.Right endobronchial foreign body causing air trapping

C.Right pleural effusion compressing the lung

D.Complete right main-bronchus obstruction with total atelectasis

Explanation: An inhaled foreign body can create partial ball-valve bronchial obstruction: air enters during inspiration but cannot escape normally during expiration, leaving the affected lung hyperinflated. A radiolucent foreign body may not itself be visible, and normal radiographs do not exclude aspiration. The clinical history and suspicion determine urgent specialist airway assessment.

2During a voiding cystourethrogram in a child with recurrent febrile urinary infections, contrast passes retrogradely from the bladder into a ureter and the renal collecting system. What abnormality is directly demonstrated?

A.Ureteropelvic junction obstruction

B.A noncommunicating parapelvic renal cyst

C.Acute renal cortical scarring

D.Vesicoureteric reflux

Explanation: Retrograde flow of bladder contrast into a ureter or collecting system demonstrates vesicoureteric reflux. A voiding cystourethrogram evaluates reflux and the lower urinary tract. Ultrasound describes dilatation and anatomy, while cortical scarring requires a different assessment; collecting-system enlargement alone would not prove reflux.

3MRI in an adult with unilateral sensorineural hearing loss shows an avidly enhancing mass centred on the internal auditory canal, extending into the cerebellopontine angle and widening the canal. Which diagnosis is most likely?

A.Vestibular schwannoma

B.Petrous meningioma

C.Arachnoid cyst

D.Epidermoid cyst

Explanation: A vestibular schwannoma is centred on the vestibular nerve in the internal auditory canal and can extend into the cerebellopontine angle. Canal widening and avid enhancement support the diagnosis. Meningiomas usually have a broader dural attachment; arachnoid and epidermoid cysts do not show this solid avid enhancement.

4An ultrasound DICOM study is prepared for an approved de-identified teaching collection. The patient name has been removed from the standard DICOM header. Which additional check is essential before release?

A.Confirm only that the filename contains no patient name

B.Inspect pixel data and other attributes for retained identifying information

C.Keep the accession number unchanged to prove that the study is original

D.Assume that deleting the Patient Name attribute removes every identifying detail

Explanation: Removing one DICOM header field is not complete de-identification. Identifiers may remain in other attributes, private fields, overlays, or burned-in image pixels. The export must be checked under the applicable confidentiality profile and institutional release process.

5A young adult develops chest pain and raised troponin after a viral illness. Cardiac MRI shows inferolateral subepicardial late gadolinium enhancement with regional oedema and sparing of the subendocardium. Which diagnosis is most likely?

A.Infarction in a single coronary artery territory

B.Isolated constrictive pericarditis

C.Acute myocarditis

D.Chronic ischaemic scar without active injury

Explanation: The combination of oedema and a non-ischaemic subepicardial enhancement pattern supports acute myocarditis in the clinical context. Infarction typically includes the subendocardium and follows a coronary distribution. CMR findings are interpreted with the clinical and laboratory assessment.

6A radiologist changes the window width and level while reviewing the same reconstructed CT series. What changes?

A.The mapping of stored voxel attenuation values to displayed shades of grey

B.The patient's radiation dose from the completed acquisition

C.The original Hounsfield value stored for each voxel

D.The reconstructed slice thickness of the existing series

Explanation: Window width and level change the display transfer function applied to the stored CT values. They do not alter the acquired dose, stored attenuation values, or slice thickness. Different reconstructions may change image data, but display windowing alone does not.

7An adult without a known extra-adrenal malignancy has a homogeneous 1.8 cm adrenal nodule measuring -5 HU on an unenhanced CT. Which diagnosis is most likely?

A.Adrenal metastasis with necrosis

B.An aggressive adrenocortical carcinoma

C.A lipid-poor pheochromocytoma

D.A lipid-rich adrenal adenoma

Explanation: A homogeneous adrenal lesion with unenhanced attenuation of 10 HU or less has imaging features of a benign lipid-rich adenoma. The -5 HU measurement reflects intracellular lipid. This imaging characterization does not establish whether the lesion secretes hormones; clinical and endocrine assessment is a separate question.

8On review of an overnight CT, a radiologist identifies an acute pulmonary embolus missed in the preliminary report. The patient has already left the emergency department. What is the best immediate professional action?

A.Replace the report silently and assume that the patient will read the portal

B.Contact the responsible clinical team urgently, issue an addendum, and document receipt and escalation

C.Wait for the next routine multidisciplinary meeting before changing the report

D.Send the finding only to an unmonitored general administrative mailbox

Explanation: A clinically important discrepancy requires prompt communication through a reliable escalation pathway as well as a corrected report. The radiologist should document who was contacted and ensure that an appropriate clinician has received the urgent finding rather than relying on passive report availability.

9A 62-year-old smoker has progressive cough. Chest radiograph shows right upper lobe volume loss, elevation of the minor fissure, and a right hilar mass. Which diagnosis is most likely?

A.Uncomplicated right upper lobe pneumonia without airway obstruction

B.Central bronchogenic carcinoma causing right upper lobe collapse

C.Pulmonary embolism with Hampton hump

D.Right upper lobe pulmonary sequestration

Explanation: Right upper lobe collapse with a hilar mass in an older smoker is highly suspicious for a central obstructing bronchogenic carcinoma. The combination of lobar volume loss and a central mass should prompt CT and bronchoscopy-based evaluation.

10A 28-year-old woman presents with acute pleuritic chest pain and dyspnoea. CT pulmonary angiography shows a central filling defect surrounded by contrast in a segmental pulmonary artery. What is the key imaging diagnosis?

A.Pulmonary artery sarcoma

B.Bronchiectasis with mucus plugging

C.Chronic pulmonary venous hypertension

D.Acute pulmonary embolism

Explanation: An intraluminal filling defect within an opacified pulmonary artery on CT pulmonary angiography is the classic finding of pulmonary embolism. Acute emboli often form central or eccentric defects with contrast surrounding them.

About the EDiR Exam

The European Diploma in Radiology is an EBR qualification endorsed by ESR and UEMS. It provides an international benchmark for general radiology and works alongside national structures and board examinations to harmonise radiology training standards.

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

EDiR is a one-day computer-based examination in three components: 78 Multiple Response Questions, 24 Short Cases, and 10 Clinically Oriented Reasoning Evaluation (CORE) practical cases. It tests knowledge, skills, and competences in general radiology against the European Training Curriculum for Radiology, Level I-II.

Time Limit

MRQs last 95 minutes, Short Cases last 90 minutes, and CORE lasts 90 minutes.

Passing Score

Part 1 combines Short Cases and MRQs as 0.3 times SC score plus 0.7 times MRQ score. Part 2 is the CORE score. Pass marks use mean minus one standard deviation, bounded by WWS 50-60% and CORE 55-70%; EBR states they stay stable at about 53% (WWS) and 58% (CORE). There is no negative marking. Candidates must pass each part and meet CORE minimum criteria.

Exam / Certification Fees

EUR 500 for ESR full members and ESR members in training; EUR 1,100 for corresponding ESR members, with possible local or session-specific fees or conditions.

EDiR: Suggested Study Strategy

1Practise both factual MRQ knowledge and short-case pattern recognition; Part 1 weights MRQ more heavily than Short Cases.

2For CORE-style cases, state the key observation, most likely diagnosis, urgent differentials, next imaging or management implication, and safety-critical communication.

3Review Level I-II general radiology broadly rather than over-focusing on one subspecialty.

4Know the official scoring mechanics: no negative marking for MRQ proportional scoring, CORE unsafe scores matter, and each part must be passed.

5Use current ESR/EBR resources, European Training Curriculum domains, and high-quality radiology case review practice rather than memorising isolated lists.

Frequently Asked Questions

Who administers EDiR?

EDiR is administered by the European Board of Radiology. The EBR page states that EDiR is endorsed by the European Society of Radiology and the European Union of Medical Specialists.

What is the current EDiR structure?

The current terms describe a one-day computer-based examination with 95 minutes of MRQs, 90 minutes of Short Cases, and 90 minutes of CORE practical-oriented cases.

How many questions are on the EDiR?

EBR's examination page lists 78 Multiple Response Questions, 24 Short Cases and 10 CORE cases. It publishes these component counts rather than a single combined question total.

Who is eligible for EDiR?

The application guide says candidates must at least be in their fifth year of national radiology training at the time of examination, and must have active national radiological society membership and ESR membership. Terms also cover certified radiologists and supervised staff radiologist experience for shorter programmes.

How is EDiR scored?

Part 1 combines Short Cases and MRQs as 0.3 times SC score plus 0.7 times MRQ score. Part 2 is CORE. Pass marks use mean minus one standard deviation within defined WWS and CORE bounds; EBR states they are usually about 53% and 58%. There is no negative marking, and candidates must pass each part.

What happens after a failed attempt?

The current terms state that candidates who fail must re-sit the entire examination. Once a candidate has passed EDiR, they are not allowed to take the EDiR examination again.
