When to use
MSK CT is the standard for complex fractures (acetabulum, calcaneus, scaphoid), orthopedic pre-surgical planning, torsional profile of limbs and focal bone lesions. For soft tissue, ligaments and bone marrow, MRI is superior.
What to evaluate
- Fractures: line, displacement, fragments, articular involvement.
- Focal bone lesions: matrix, margin pattern, periosteal reaction.
- Articular surfaces and congruence.
- Intra-articular loose bodies.
- Adjacent soft tissues (limited vs MRI).

Frequently asked
- When CT instead of XR for fracture?
- Strong clinical suspicion with inconclusive radiograph (scaphoid, occult scaphoid, ribs, coronoid), complex fractures for surgical planning, and assessment of union.
- Lytic bone lesion — when MRI complements?
- Whenever primary tumor or metastasis is suspected — MRI better evaluates the marrow component and soft-tissue extension.
