Most Repeated FCPS Part 1 Radiology MCQs: High-Yield Subjects

The subjects that carry the most weight in FCPS Part 1 Radiology — Anatomy, Pathology and Radiation Physics — with sample MCQs for each.

FCPS Part 1 Radiology draws most of its questions from cross-sectional Anatomy, Pathology and Physiology, with Radiation Physics & Safety as the section unique to this paper. Below is a sample across the subjects that carry the most weight, in the same one-line format the real exam uses. Some candidates search for these as "recalls" — questions reconstructed from memory by past sitters; the concepts they cover overlap heavily with the high-yield subjects below.

Anatomy

1. The trachea bifurcates into the right and left main bronchi at approximately which vertebral level?

A) T1
B) T4–T5 ✅
C) T8
D) L1

2. On a standard PA chest radiograph, loss of the right heart border ("silhouette sign") most classically indicates consolidation in the:

A) Right upper lobe
B) Right middle lobe ✅
C) Right lower lobe
D) Lingula

Radiation Physics & Safety

3. The SI unit of absorbed radiation dose is the:

A) Sievert
B) Becquerel
C) Gray ✅
D) Curie

4. Which imaging modality uses no ionizing radiation at all?

A) CT
B) Fluoroscopy
C) MRI ✅
D) Nuclear medicine scan

Musculoskeletal Radiology

5. Which modality is most sensitive for detecting an occult (radiographically-negative) fracture?

A) Plain X-ray
B) MRI ✅
C) Ultrasound
D) Fluoroscopy

Contrast & Imaging Basics

6. Gadolinium-based contrast agents are used with which imaging modality?

A) CT
B) Ultrasound
C) MRI ✅
D) Plain radiography

Why This Split Reflects the Real Paper

Anatomy alone makes up the single largest share of the FCPS Part 1 Radiology question pool, which is why cross-sectional anatomy (not just imaging findings) deserves proportionally more revision time than any single radiology subspecialty topic.

Looking for a Mock Exam, Not Just More Questions to Read?

If what you actually want is a timed FCPS Part 1 Radiology mock exam — not another static list to read through — that's exactly what the free sample on the Radiology question bank page gives you: the same timed, explained format as the full bank, no separate "mock test" product to buy or download.
