Summary

Magnetic resonance (MR) imaging offers objective criteria for diagnosing plantar fasciitis. This heel pain condition shows significantly increased plantar fascia thickness and signal intensity on MR scans, aiding diagnosis.

Area of Science:

  • Radiology
  • Orthopedics
  • Medical Imaging

Background:

  • Plantar fasciitis diagnosis can be challenging due to similar presentations of other heel pain conditions.
  • Objective diagnostic methods are needed to differentiate plantar fasciitis from other pathologies.

Purpose of the Study:

  • To establish objective morphologic criteria for diagnosing plantar fasciitis using magnetic resonance (MR) imaging.
  • To evaluate the utility of MR imaging in assessing plantar fascia thickness and signal intensity.

Main Methods:

  • MR imaging (sagittal T1-weighted, coronal intermediate and T2-weighted sequences) was performed on eight patients with plantar fasciitis and control groups.
  • Plantar fascia thickness and signal intensity were measured and compared between symptomatic and asymptomatic feet.

Main Results:

  • Patients with plantar fasciitis exhibited significantly increased plantar fascia thickness (P < .0001) compared to controls.
  • Increased thickness was observed in both sagittal (7.40 mm vs. 3.22 mm) and coronal (7.56 mm vs. 3.44 mm) views.
  • Nine out of ten feet with plantar fasciitis showed increased signal intensity within the plantar fascia on MR images.

Conclusions:

  • MR imaging provides objective morphologic criteria for diagnosing plantar fasciitis.
  • MR imaging can differentiate plantar fasciitis from other heel pain causes by assessing fascia thickness and signal changes.
