MRI Wrist/Hand — Dictation, Appropriateness, and Dose for Residents

The ortho resident calls you from the ED. 22-year-old, fell on an outstretched hand, snuffbox tenderness, but the X-rays are stone-cold normal. They’re convinced it’s an occult scaphoid fracture and want the MRI to prove it. Your attending expects a clean, structured report that not only finds the fracture but also clears the key ligaments and the Triangular Fibrocartilage Complex (TFCC). Getting this right means knowing exactly what to look for and how to structure the report before you even open the case. When I was a resident, this was the kind of case where having a solid template was the difference between a confident read and a late-night scramble through textbooks. We’ve built tools and guides to make this easier, which you can find over at the residents and fellows resource hub.

What an MRI of the Wrist or Hand Covers and What Attendings Look For

An MRI of the wrist or hand is the problem-solver when radiographs are inconclusive. It provides exquisite detail of the complex anatomy, from the tiny carpal bones and intrinsic ligaments to the tendons and nerves. This isn’t just a fracture hunt; it’s a comprehensive evaluation of all potential sources of wrist pain.

Your attending will expect you to systematically evaluate and comment on several key areas, especially when the indication is trauma or chronic pain. The most common indications include:

• Suspected occult scaphoid fracture (with negative X-rays)
• Evaluation of the scapholunate and lunotriquetral ligaments for tears
• Assessment of the Triangular Fibrocartilage Complex (TFCC) for injury
• Atypical carpal tunnel syndrome symptoms
• Characterization of a wrist or hand mass
• Concern for avascular necrosis (Kienbock’s or Preiser’s disease)
• Early detection of inflammatory arthritis changes

A strong report will address the primary clinical question while also methodically clearing these other critical structures.

Radiology Report Template for MRI Wrist/Hand

This template provides a reliable framework. Use it as a starting point for your macros in PowerScribe or your preferred dictation system. It’s designed to ensure you don’t miss the common pathologies your attending will be looking for.

Technique

Multiplanar, multisequence MRI of the [right/left] wrist was performed without intravenous contrast. Sequences include coronal T1 and PD/T2 fat-saturated, axial T1 and T2 fat-saturated, and sagittal PD/T2 fat-saturated images.

[If contrast was used, modify: “following the administration of [volume] mL of [contrast_name] macrocyclic gadolinium-based contrast agent.”]

Findings

BONES: The carpal bones are normal in alignment. No acute fracture or dislocation. Bone marrow signal is homogeneous. No evidence of avascular necrosis of the lunate (Kienbock’s) or scaphoid (Preiser’s). The distal radius and ulna are unremarkable.

[Dictate positives: e.g., “Linear T1 hypointensity with surrounding marrow edema in the scaphoid waist is consistent with an acute non-displaced fracture.” or “T1 hypointense signal and collapse of the lunate are seen, consistent with advanced Kienbock’s disease.”]

INTRINSIC LIGAMENTS:
– Scapholunate Ligament: Intact. The scapholunate interval is normal, measuring [X] mm.
– Lunotriquetral Ligament: Intact.

[Dictate positives: e.g., “There is discontinuity of the scapholunate ligament with widening of the scapholunate interval, consistent with a complete tear and scapholunate dissociation.”]

TRIANGULAR FIBROCARTILAGE COMPLEX (TFCC): The triangular fibrocartilage and radioulnar ligaments are intact. The distal radioulnar joint is congruous.

[Dictate positives: e.g., “A linear T2 hyperintense signal extends through the central articular disc of the TFCC, consistent with a traumatic tear.”]

CARPAL TUNNEL: The median nerve is normal in size and signal intensity at the carpal tunnel inlet. The flexor retinaculum is normal in thickness and contour. No space-occupying lesion is identified.

[Dictate positives: e.g., “The median nerve is enlarged and demonstrates T2 hyperintense signal at the level of the pisiform. There is palmar bowing of the flexor retinaculum. Findings are consistent with carpal tunnel syndrome.”]

TENDONS: The extensor and flexor tendons are intact and demonstrate normal signal intensity. No tenosynovitis.

SOFT TISSUES: No discrete soft tissue mass or abnormal fluid collection. The visualized musculature is unremarkable.

[Dictate positives: e.g., “A well-circumscribed, T2 hyperintense, lobulated fluid collection arising from the dorsal scapholunate interval is consistent with a ganglion cyst.”]

Impression

1. Normal MRI of the [right/left] wrist.
2. No acute fracture, ligamentous injury, or evidence of avascular necrosis.

[Or, if positive:]

1. Acute non-displaced fracture of the scaphoid waist.
2. Intact scapholunate ligament and TFCC.

Free Radiology Template Sources

Building a personal library of templates takes time. While you’re developing your own, two great free repositories exist that can provide excellent starting points for a wide range of studies. These are maintained by the radiology community and are worth bookmarking.

• RadReport.org: Curated by the Radiological Society of North America (RSNA), this is a comprehensive library of peer-reviewed templates that align with best practices. You can find it at https://radreport.org/.
• Radiology Templates (AU): This is an Australian-maintained library with a clean interface and practical templates for daily use in MSK, neuro, body, and more. Check it out at https://www.radiologytemplates.com.au/home-page/.

The Next-Level Move: From Free-Form Dictation to Structured Report

A good template is your safety net, but the real goal is to dictate your findings naturally and have the structure build itself around your words. This is where AI-powered tools can significantly streamline your workflow. Instead of navigating a complex macro, you can simply dictate the positive findings—”acute scaphoid fracture,” “complete tear of the scapholunate ligament,” “enlarged median nerve at the carpal tunnel inlet”—and the system does the rest.

Tools like GigHz Precision AI are designed for this. You dictate what you see, and the AI refines it into a clean, structured report based on pre-loaded templates from the American College of Radiology (ACR) and Society of Interventional Radiology (SIR). It also helps ensure that any necessary Clinical Decision Support (CDS) frameworks are applied correctly. This approach helps you create high-quality, attending-ready reports faster, letting you focus on the images, not the clicks.

When Should You Order an MRI of the Wrist or Hand? ACR Appropriateness Criteria

Knowing when an MRI is the right next step is crucial. The American College of Radiology (ACR) provides evidence-based guidelines for various clinical scenarios. For wrist and hand imaging, MRI is often the definitive study after initial radiographs are unrevealing.

For an adult with chronic hand or wrist pain where initial X-rays are normal or show nonspecific arthritis, an MRI is rated as Usually Appropriate. This is the go-to for evaluating the ligaments, TFCC, and cartilage that X-rays can’t see. Similarly, if radiographs show an old scaphoid fracture and the concern is for nonunion, osteonecrosis, or post-traumatic arthritis, MRI is also Usually Appropriate to assess bone viability and soft tissues.

In cases of acute trauma to the hand or wrist, MRI is Usually Appropriate when there’s high suspicion for an occult fracture or a significant ligamentous injury despite negative initial X-rays. For suspected tendon pathology or tenosynovitis in a patient with chronic pain, MRI is again Usually Appropriate.

When symptoms are suspicious for carpal tunnel syndrome but the presentation is atypical, MRI is considered Usually Appropriate to rule out other causes of nerve compression, like a mass. For suspected inflammatory arthritis (like rheumatoid arthritis) or crystalline arthropathy (gout, pseudogout) with inconclusive radiographs, an MRI is also Usually Appropriate to detect early synovitis, erosions, and bone marrow edema not visible on other modalities.

MRI Wrist/Hand Imaging Protocol — Sequences and Technical Parameters

A high-quality wrist MRI depends on a dedicated protocol with a small field of view and thin slices to resolve the fine anatomical structures. While specifics can vary by institution, the core sequences are standardized to provide a comprehensive diagnostic evaluation.

The protocol typically uses a dedicated wrist coil for high signal-to-noise. Key parameters include a tight field of view (FOV) of 100-120 mm and thin slices (2-3 mm) to maximize spatial resolution. Intravenous contrast is not routine but may be added for evaluating tumors, infection, or inflammatory arthritis.

Common protocol pitfalls: The most common issue is patient motion, which can degrade the high-resolution images. Using a comfortable, well-padded coil and clear instructions can minimize this. Another pitfall is an FOV that is too large, which compromises spatial resolution and can make it impossible to evaluate small structures like the intrinsic ligaments. Always ensure the FOV is tightly centered on the carpus.
