Mri In Stress Fractures

  1. 1. Ruling out Fractures Use of magnetic resonance imaging to diagnose fracture in light of negative plain films
  2. 2. Case Report • 48 year old white female with no history of trauma reports having 2-3 months history of discomfort in the right foot and ankle • A presumptive diagnosis of common heel pain or Plantar fasciitis is made
  3. 3. Case Report • Plain films show no pathology to foot or ankle • Patient has continued pain after a period of soft casting of the site and Non-steroidal anti-inflammatory therapy
  4. 4. Case Report • A 3-phase technetium™ bone scan is done to look for other pathology and is hot at the calcaneus of the right foot. • A magnetic resonance imaging study is done and shows a through and through calcaneal fracture at the midbody aspect of the tuber
  5. 5. Imaging • Plain film read as no pathology although a subtle area of sclerosis is noted at the superior calcaneus
  6. 6. 3-phase technetium™ bone scan • Scan is hot throughout the calcaneus
  7. 7. MR Images • Clear line of fracture seen through the body of the os calcis
  8. 8. MR Images
  9. 9. MR Images
  10. 10. Conclusions • The use of the MR scan in light of negative films allowed visualization of the fracture • Continued symptomotology with negative films would indicate further studies • As the 3-phase scan didn’t locate the fracture, the magnetic resonance imaging was actually more cost- effective
