Summary

Low-field MRI effectively detects acute scaphoid fractures and other wrist injuries. This imaging technique reveals subtle fractures missed by X-rays and identifies additional traumatic lesions, improving diagnostic accuracy for wrist trauma.

Area of Science:

  • Orthopedic imaging
  • Musculoskeletal radiology
  • Diagnostic imaging

Background:

  • Scaphoid fractures are common wrist injuries often missed by initial radiography.
  • Accurate diagnosis is crucial for preventing long-term complications such as nonunion and avascular necrosis.

Purpose of the Study:

  • To evaluate the utility of low-field magnetic resonance imaging (MRI) in diagnosing acute scaphoid fractures.
  • To assess MRI's capability in detecting associated wrist injuries.

Main Methods:

  • Low-field MRI was performed on 18 consecutive patients with suspected acute scaphoid fractures.
  • T1-weighted images were analyzed for signal intensity changes indicative of fracture.
  • Radiographic findings were compared with MRI results.

Main Results:

  • MRI identified 11 scaphoid fractures, while 7 were initially considered normal.
  • Two radiologically evident fractures were not detected by MRI, later identified as old injuries.
  • MRI revealed numerous additional wrist lesions, including triangular fibrocartilage tears (7), scapholunate ligament tears (4), and other carpal fractures (7).

Conclusions:

  • Low-field MRI is a valuable tool for diagnosing acute scaphoid fractures, particularly when radiography is inconclusive.
  • MRI demonstrates superior sensitivity for detecting occult fractures and associated ligamentous and cartilaginous injuries in the wrist.
