title: Plantar plate tear diagnosis using dual-energy computed tomography collagen material decomposition application.
abstract: Computed tomography (CT) scans of the feet are often obtained in the context of trauma or suspected stress fracture mainly for assessment of osseous pathology. However, compared with magnetic resonance imaging (MRI), soft-tissue assessment on CT is typically limited. Plantar plate injury is a common cause of metatarsalgia and, along with other soft-tissue injuries, is typically diagnosed with MRI. We present a case of plantar plate tear detected on dual-energy CT scan using a collagen material decomposition algorithm confirmed on subsequent MRI.
