Diagnostic accuracy of virtual non-calcium dual-energy computed tomography in the detection of acute occult ankle and calcaneus fractures.

ABSTRACT:

Background

Individuals with acute occult ankle and calcaneus fractures usually need to undergo additional magnetic resonance imaging (MRI) to confirm the diagnosis. In some cases, dual-energy computed tomography (DECT) is more convenient and efficient than MRI. This study aimed to assess the diagnostic accuracy of virtual non-calcium (VNCa) DECT in detecting acute occult ankle and calcaneus fractures.

Methods

From January 2022 to February 2024, adult patients presenting with ankle and calcaneal trauma but showing negative or inconclusive results on radiographs were enrolled in this prospective study. Ankle and calcaneus imaging was performed using DECT and MRI. Bone marrow edema (BME) was assessed by consolidating the MRI scan readings. Concurrently, the identification of fr
