摘　　要：磁共振成像具有良好的软组织分辨率同时不存在电离辐射,被广泛地应用于人体多个部位的检查,但人体存在一些T2值超短的物质,如骨皮质、肌腱、韧带、肺组织等,使用常规磁共振成像序列无法对这类组织进行成像。随着磁共振成像技术的发展,磁共振超短回波时间(magnetic resonance imaging ultrashort echo time,MRI-UTE)序列的应用使短T2组织成像成为可能,本文就近年来MRI-UTE序列应用进展进行综述。Magnetic resonance imaging has good soft tissue resolution and no ionizing radiation,so it is widely used in many parts of the human body,but there are some substances with ultra-short T2 value in human body.such as bone cortex,tendons,ligaments,lung tissue and so on,this kind of tissue cannot be imaged by conventional magnetic resonance imaging sequence.With the development of magnetic resonance imaging technology,the application of Magnetic Resonance Imaging Ultrashort echo time(Magnetic Resonance Imaging Ultrashort echo time.MRI-UTE)sequence makes short T2 tissue imaging possible.The research progress in the application of ultrashort echo time series in recent years was reviewed in this paper.
