The Intermediate Module (IMM) is the mid-training examination of the CPSP fellowship in Diagnostic Radiology. It checks that you have mastered the foundations — anatomy, physics and core pathology — before advanced training and the FCPS Part II exit exam. This guide explains eligibility, the format and a practical study plan.
Eligibility and requirements
- At least two years of radiology training in a CPSP-accredited programme.
- Registration with the CPSP's Research and Training Monitoring Cell (RTMC).
- Completion of the four mandatory workshops: Computer and Internet, Research Methodology/Biostatistics/Article Writing, Communication Skills (SCoPE) and Basic Life Support.
- For your research: the synopsis must be approved before research starts, and the current curriculum asks for it to reach the Research Evaluation Unit at least six months before your IMM.
IMM exam format
| Component | What it involves |
|---|---|
| Theory | Best choice questions (BCQs) on anatomy, physics and core pathology; must be passed first |
| TOACS | Image-based stations testing recognition and interpretation of common findings |
High-yield IMM topics
- Radiological anatomy: cross-sectional anatomy of brain, chest, abdomen and pelvis; normal variants that mimic disease.
- Physics and radiation protection: X-ray production, CT, MRI and ultrasound principles, dose units and ALARA.
- Signs and classic appearances: the named radiological signs examiners love.
- Contrast media: reactions, nephropathy risk and management.
- Common pathology: pneumonia, stroke, fractures, bowel obstruction, renal stones and other everyday diagnoses.
Our 587 free IMM flashcards cover anatomy, physics, signs and syndromes across 12 topics.
An 8-week IMM study plan
| Week | Focus |
|---|---|
| 1–2 | Physics: X-ray, CT, MRI, ultrasound and radiation protection |
| 3–4 | Anatomy: neuro, head and neck, chest, abdomen, pelvis and MSK |
| 5–6 | Core pathology by system, with daily image review |
| 7 | Signs, contrast media and mixed BCQ practice |
| 8 | Timed mock papers and image-based TOACS practice |

- Look at images every day: TOACS rewards pattern recognition, not just reading.
- Learn physics with numbers: BCQs often hinge on a single unit or threshold.
- Start the synopsis early: research deadlines can delay your exam eligibility.
- Read our FCPS Part II guide to plan the rest of your training.
Frequently asked questions
When can I sit the IMM in Diagnostic Radiology?
The Intermediate Module (IMM) can be taken after two years of radiology training, once you are registered with the CPSP's training monitoring body (RTMC) and have completed the mandatory workshops.
What is the format of the IMM radiology exam?
The IMM has a theory component in best choice question (BCQ) format, followed by an image-based TOACS. You must pass theory before you can sit the TOACS. Confirm the current format on the CPSP website.
Which workshops are mandatory before IMM?
The current CPSP curriculum lists four: Computer and Internet skills, Research Methodology/Biostatistics/Article Writing, Communication Skills (SCoPE) and Basic Life Support.
What topics does the IMM focus on?
IMM emphasises core knowledge: radiological anatomy, physics and radiation protection, and the imaging appearances of common pathology across all systems.
Do I have to pass IMM before FCPS Part II?
Yes. Residents may continue into advanced training, but IMM must be passed before the FCPS Part II exit examination.
