Background: Ultrasound has proved its ability to detect changed
associated with plantar fasciitis (PF). However, magnetic resonance
imaging (MRI) is still the gold standard technique for the diagnosis
of such condition. Aim of the work: This study was conducted to
evaluate the diagnostic capability of ultrasonography for the
detection of plantar fasciitis in comparison with MRI in diabetic foot
patients. Subjects and methods: This prospective case control
study included 40 subjects; 30 cases diagnosed with PF in addition
to 10 controls. All subjects were subjected to history taking, clinical
examination, plantar US and MRI examination for assessment of PF
signs. Results: Basic demographics were comparable between cases
and controls. By both US and MRI, plantar fascial thickness showed
a significant increase, in both longitudinal and transverse planes, in
cases compared to controls. US had sensitivity and specificity of
92.6 and 100% respectively, with a diagnostic accuracy of 93.3%
for the detection of focal thickening and fascial abnormal signaling. US had sensitivity and
specificity of 94.4 and 100% in detecting soft tissue edema, while it had poor sensitivity for
calcaneal spur, and no sensitivity for bone marrow edema. Conclusion: US could be considered
as good alternative tool compared to MRI in the diagnosis of PF, as it was able to detect most
signs of such pathology. However, it is recommended to be performed by an experienced
radiologis
