Abstract

Traditional monoenergetic computed tomography (CT) scans in musculoskeletal imaging provide excellent detail of bones but are limited in the evaluation of soft tissues. Dual-energy CT (DECT) overcomes many of the traditional limitations of CT and offers anatomical details previously seen only on MR imaging. In addition, DECT has benefits in the evaluation and characterization of arthropathies, bone marrow edema, and collagen applications in the evaluation of tendons, ligaments, and vertebral discs. There is current ongoing research in the application of DECT in arthrography and bone mineral density calculation.

摘要

传统的单能量计算机断层扫描（CT）在肌肉骨骼成像中提供了极好的骨骼细节，但在软组织评估方面存在局限性。双能 CT（DECT）克服了 CT 的许多传统局限性，提供了以前只能在磁共振成像（MR 成像）上看到的解剖细节。此外，DECT 在评估和特征化关节病、骨髓水肿以及在评估肌腱、韧带和椎间盘方面的胶原应用方面具有优势。目前，DECT 在关节造影和骨密度计算中的应用正在进行研究。
