The purposes of this review are to describe commonly available 3D MRI techniques and to discuss the literature to date regarding the utility of such techniques in the assessment of internal derangement of joints.
Long acquisition and postprocessing times and limited contrast characteristics have generally prohibited routine use of 3D MRI in clinical practice. However, technical advances, including higher-field-strength MRI systems, high performance gradients, high-resolution multichannel coils, and pulse sequences with shorter acquisition times, have made feasible 3D isotropic MRI with reasonable acquisition times.
本综述旨在描述常用的 3D MRI 技术，并讨论迄今为止有关这些技术在关节内紊乱评估中的应用的文献。
较长的采集和后处理时间以及有限的对比特性通常限制了 3D MRI 在临床实践中的常规应用。然而，技术进步，包括更高场强 MRI 系统、高性能梯度、高分辨率多通道线圈和具有更短采集时间的脉冲序列，使得具有合理采集时间的 3D 各向同性 MRI 成为可能。
