FRCR Physics is the physics module of the First FRCR examination (Part 1). Radiology trainees sit it to show they can apply imaging physics — not recite a textbook — before moving on to the clinical FRCR papers. People search “FRCR Physics” and “FRCR Part 1 Physics” for the same sitting.
What the FRCR Physics exam actually is
The First FRCR has two modules: Anatomy and Physics. FRCR Physics tests whether you can reason about how images are formed, why they fail, and how dose and safety constraints change what you do at the console. It is not a general “medical physics degree” paper and it is not the same as FRCR Part 2A/2B.
- Who sits it: clinical radiology trainees (and some related pathways) preparing for First FRCR.
- What it rewards: precise true/false reasoning on X-ray, CT, MRI, ultrasound, nuclear medicine, fluoroscopy, and radiation protection.
- What it does not reward: memorising a rival question-book title or hunting a “physics MCQs for the Part 1 FRCR PDF.”
Format: why people say MCQ when the paper is true/false
Search demand still uses “FRCR Physics MCQ” because older books and forums labelled every stem an MCQ. The live physics paper is a true/false (assertion) exam: a stem, then several statements you mark true or false. One absolute word can flip a statement. Practising five-option “best answer” quizzes trains the wrong reflex.
- Read the modality in the first line before you judge the statement.
- Treat always / never / only as a pause, not an automatic False.
- Review the explanation for every miss — the trap is the lesson, not the tick.
What FRCR Part 1 Physics covers
The RCR syllabus is the source of truth. In practice, high-yield FRCR Physics clusters look like this — use them to map a first pass, then drill items by topic.
- X-ray production, interactions, and image quality (including digital radiography).
- CT physics — reconstruction, artefacts, CTDIvol vs DLP.
- MRI — contrast, sequences, safety.
- Ultrasound and Doppler — wave physics and artefacts.
- Fluoroscopy / interventional dose — ABC, DAP, staff protection.
- Nuclear medicine — radionuclides, SPECT/PET basics.
- Radiation protection throughout — quantities, legislation themes, ALARA.
How to start (without another “comprehensive guide”)
If you are months out: cover foundations in X-ray and image quality first, then CT and MRI, and keep radiation protection in every week. If you are inside a month: stop collecting new PDFs. Run a timed mixed set, write down the three topics that cost marks, and spend the remaining weeks on those plus incorrects.
- Use Farr (or your chosen core text) for mechanisms — not as a highlighter project.
- Use a true/false bank that matches the paper, with explanations you can say out loud.
- Sit timed mocks as measurement, then Topic Focus the failing modalities within 48 hours.
Resources worth using — and searches to ignore
A named MCQ book or a BMJ question pack can be a supplement. They are not a syllabus. Queries such as “Get Through First FRCR MCQs for the Physics Module” or “BMJ FRCR Physics” are shopping queries for those products. Ranking a generic article for them helps the publisher, not your sitting.
- Core text for mechanisms (commonly Farr’s Physics for Medical Imaging).
- RCR First FRCR pages for dates, fees, and the current format notice.
- Exam-style true/false practice with topic analytics — that is what FRCRX is built for.
