Intrasubject side\u2010to\u2010side variability must be minimal.

Small structures of the ankle and foot were evaluated bilaterally by 2 musculoskeletal radiologists in separate sessions. The deep peroneal nerve, superior extensor retinacula, calcaneofibular ligament, superior peroneal retinacula, tibialis posterior tendon, tibial nerve, Achilles tendon, plantaris tendon, plantar fascia, and sural nerve were considered.

The mean values and standard deviation for all the structures were 0.36\u2009\u00b1\u20091.85\u2009mm. The overall coefficient of variation was 18.5%.
