Thickened plantar fascia best identified in longitudinal axis from its insertion into calcaneus is essentially diagnostic of plantar fasciitis (and lack of enlargement essentially rules out the diagnosis).
placing the linear scanner and the longitudinal axis of the foot can identify here the calcaneus again with its bony shadow and normal plantar fascia should insert here at the base of the calcaneus and here we see a significantly edematous plantar fascia that measures approximately one centimeter in its height from the edge here where it inserts on the calcaneus to here this is essentially diagnostic of plantar fasciitis with such a large area and we can see that the fat pad that usually cushions the plantar fascia has also degraded and been quite compressed in this patient with plantar fasciitis you
