There is evidence that the use of imaging aids in the assessment of progressive collapsing foot deformity (PCFD). The following conventional radiographs (CRs) are necessary in the assessment of PCFD patients: anteroposterior (AP) foot, AP or mortise ankle, and lateral foot. If available, a hindfoot alignment view is strongly recommended. If available, computed tomography (CT) is strongly recommended for surgical planning. When CT is obtained, important findings to be assessed are sinus tarsi impingement, subfibular impingement, increased valgus inclination of the posterior facet of the subtalar joint, and subluxation of the subtalar joint at the posterior and/or middle facet.

影像学辅助检查可用于评估进行性距下关节骨塌陷（PCFD）。评估 PCFD 患者时需要进行以下常规 X 线检查：足正位、踝正位或踝穴位、足侧位。如果可能，强烈推荐跟骨侧位。如果可能，强烈推荐 CT 用于手术计划。当获得 CT 时，需要评估的重要发现包括跗骨窦撞击、腓骨撞击、距下关节后关节面内翻增加和距下关节后关节面和/或中关节面半脱位。
