Pitfalls of wrist MR imaging

Area of Science:

• Radiology
• Orthopedics
• Medical Imaging

Background:

• Wrist pain is a common patient complaint requiring accurate diagnosis.
• Radiologists play a crucial role in evaluating wrist pain, guiding treatment, and surgical planning.
• Magnetic Resonance Imaging (MRI) is a primary diagnostic tool for wrist pathology.

Purpose of the Study:

• To review normal anatomic variants of the wrist relevant to MRI interpretation.
• To highlight potential danger areas and pitfalls encountered during wrist MRI analysis.
• To enhance the radiologist's diagnostic accuracy for wrist pain.

Main Methods:

• Review of current literature on wrist anatomy and MRI.
• Analysis of common and uncommon anatomic variants.
• Identification of imaging findings indicative of potential diagnostic challenges.

Main Results:

• Detailed description of normal wrist anatomy on MRI.
• Illustration of common variants that may mimic pathology.
• Identification of critical structures and potential injury patterns.

Conclusions:

• Accurate interpretation of wrist MRI requires knowledge of normal variants.
• Awareness of potential pitfalls improves diagnostic confidence and patient care.
• This review provides a guide for radiologists interpreting wrist MRI for pain evaluation.
