Abstract
This review article aims to summarize the available literature regarding the utility of Dual-Energy CT (DECT) in spine imaging. DECT using virtual non-calcium images, virtual monoenergetic images, and material decomposition techniques have shown promise in bone marrow edema visualization associated with vertebral fractures, metallic artifact reduction related to spinal hardware, axial monosodium urate deposit detection, bone marrow composition evaluation, and bone marrow lesion identification. In our experience, DECT may also be an assuring technique in evaluation of disc degeneration, and disc herniation. DECT imaging of the spine has numerous clinical applications, potential advantages over single-energy CT and other imaging modalities, and future promising avenues.
