This review article summarizes recent technical developments in ultrashort echo time (UTE) magnetic resonance imaging of musculoskeletal (MSK) tissues with short-T2 relaxation times. A series of contrast mechanisms are discussed for high-contrast morphological imaging of short-T2 MSK tissues including the osteochondral junction, menisci, ligaments, tendons, and bone. Quantitative UTE mapping of T1, T2*, T1ρ, adiabatic T1ρ, magnetization transfer ratio, MT modeling of macromolecular proton fraction, quantitative susceptibility mapping, and water content is also introduced. Met and unmet needs in MSK imaging are discussed. EVIDENCE LEVEL: 1 TECHNICAL EFFICACY: Stage 3.
这篇综述文章总结了最近在短 T2 弛豫时间的肌肉骨骼（MSK）组织的超短回波时间（UTE）磁共振成像方面的技术进展。讨论了一系列对比机制，用于高对比度形态成像短 T2 MSK 组织，包括骨软骨结合处、半月板、韧带、肌腱和骨骼。还介绍了 T1、T2*、T1ρ、绝热 T1ρ、磁化转移率、大分子质子分数的 MT 建模、定量磁化率映射和含水量的定量 UTE 映射。讨论了 MSK 成像中的满足和未满足的需求。证据水平：1 技术功效：第 3 阶段。
