Wrist MRI: What to Expect and What It Shows
The wrist packs a dozen small bones and a web of ligaments into a space the size of a golf ball — and MRI is the only camera that reads all of it clearly.
A wrist MRI images the small bones, ligaments, cartilage (including the TFCC), and bone marrow of the wrist in detail nothing else matches, in 30–45 painless minutes. You lie with the wrist positioned in a small coil, arm supported overhead or at your side. Most exams need no contrast; it finds TFCC tears, scapholunate ligament injuries, occult fractures, and early Kienbock's disease.
Why would I need a wrist MRI?
Wrist pain after a fall with normal X-rays (occult scaphoid fractures famously hide), ulnar-sided wrist pain (the TFCC lives there), clicking or instability suggesting ligament tears, persistent pain after sprains, ganglion cysts, and Kienbock's disease (avascular necrosis of the lunate) in younger adults. When the wrist hurts and the X-ray shrugs, MRI is the definitive next step.
What happens during a wrist MRI?
You lie on the table with your wrist in a small dedicated coil — usually with your arm raised overhead or resting at your side, whatever the scanner layout favors. The position is the question to ask when booking. The technologist sequences while you hold the hand motionless; even a finger twitch blurs images of structures measured in millimeters. The exam takes 30–45 minutes, no injection for most.
What does a wrist MRI show?
- TFCC tears: the triangular cartilage cushioning the pinky side — a classic MRI diagnosis
- Ligaments: scapholunate and lunotriquetral tears causing instability
- Occult fractures: especially scaphoid — where a missed fracture can cost the bone its blood supply
- Kienbock's disease: early lunate avascular necrosis
- Bone bruises, cysts, ganglia: the small-print causes of chronic wrist pain
Why does a missed scaphoid fracture matter so much?
The scaphoid has a tenuous blood supply — a fracture through its waist can cut off the far half, causing avascular necrosis and arthritis that a simple cast, applied early, would have prevented. X-rays miss up to a fifth of scaphoid fractures in the first week; MRI catches them immediately. That is why "fall on outstretched hand plus snuffbox tenderness plus normal X-ray" equals MRI in emergency and sports medicine.

Contact SATMED HealthFrequently asked questions about wrist MRI
Is a wrist MRI claustrophobic?
Mildly — the arm-overhead position can feel long for some. Ask about positioning options when booking.
Can MRI find a fracture that X-ray missed?
Yes — scaphoid and other occult wrist fractures are one of its signature findings.
What is the TFCC?
The triangular fibrocartilage complex cushioning the pinky side of the wrist — a common, MRI-diagnosable cause of ulnar wrist pain.
Do I need contrast for a wrist MRI?
Usually no. It is reserved for infection, tumor, or complex surgical questions.
What is Kienbock's disease?
Avascular necrosis of the lunate bone — MRI catches it earliest, while treatment can still save the bone.
Will the MRI tell me if I need wrist surgery?
It maps the damage precisely; surgery decisions combine imaging with examination and your demands on the wrist.
