摘　　要：超短回波时间(UTE)和零回波时间(ZTE)MRI可有效显示并定性、定量评估软骨、韧带及骨皮质等短T2结构,对于临床早期诊断膝关节炎有重要意义,由此有望实现软组织及骨骼一站式高分辨成像。本文就UTE和ZTE MR成像原理及其临床评估膝关节炎应用进展进行综述。Ultrashort echo time(UTE)and zero echo time(ZTE)MRI can effectively display and qualitatively,quantitatively evaluate short T2 structures such as cartilage,ligament and cortical bone,being of great significance for early clinical intervention of knee osteoarthritis and one-stop high-resolution imaging of soft tissue and bone.The principles and clinical application progresses of UTE and ZTE MR imaging for evaluating knee osteoarthritis were reviewed in this article.
