Comparison between US and MRI in terms of affordability, clinical application, image quality and suitability for various clinical settings.

Criteria	Ultrasound	MRI
Cost	Less expensive	More expensive
Accessibility	Widely available	Limited availability
Safety	Non-invasive and no radiation exposure	Non-invasive but exposure to magnetic field and radio waves
Imaging speed	Real-time imaging	Longer acquisition time
Image quality	Good for superficial structures, bones, and joints	Better for soft tissue contrast
Sensitivity	Can detect small nerve injuries	High sensitivity
Specificity	Less specific in determining the type of injury	More specific in determining the type of injury
Patient comfort	Comfortable and well-tolerated	Claustrophobic and noisy environment
Operator dependency	Highly operator-dependent	Less operator-dependent
Suitability for different types of injuries	Suitable for evaluating peripheral nerve entrapment and focal neuropathies	Suitable for evaluating more complex injuries, such as nerve root avulsion or plexus injuries
