中文摘要：
核磁共振成像(MRI)技术拥有良好的软组织分辨率且无电离辐射,在临床和科研方面均得到了广泛应用。超短回波时间序列(UTE)在一定程度上弥补了MRI在短T2组织成像的弱点,使MRI的应用更加广泛。由UTE得到的派生序列有脂肪抑制UTE、单绝热反转恢复UTE、双回波差UTE等。本文介绍核磁共振超短时间回波序列(MR-UTE)技术的发展、原理及其应用,并对MR-UTE技术的发展方向进行展望。

英文摘要：
Magnetic resonance(MR) imaging technology has been widely used in clinical and scientific researches because of its good soft tissue resolution and no ionizing radiation. Ultrashort echo time sequence(UTE) compensates for the weakness of MR imaging in short T2 components to a certain extent, making the application of MR imaging more widely. Sequences derived from UTE include fat-suppressed UTE, single adiabatic inversion recovery UTE, dual-echo UTE and so on. The development,principle and application of MR-UTE are introduced in this review, and its development trends are prospected.
