II. Indication
- Suspected Stress Fracture despite negative serial XRay
- New gold standard for Stress Fracture imaging (supplanting bone scan)
III. Epidemiology: Efficacy
- Test Sensitivity: High up to 100% in some studies (at least as good as bone scan)
- Test Specificity: High (better than bone scan)

IV. Advantages
- Highest efficacy of any imaging modality
- Identifies marrow edema (stress reaction) and subtle Fracture lines
- Evaluates regional soft tissue
- Best detail for differentiating Stress Fractures from other causes
- No radiation exposure
V. Disadvantages
- Higher cost than other Stress Fracture imaging
