Recently introduced MRI techniques facilitate accelerated examinations or increased resolution with the same duration. Further techniques offer homogeneous image quality in regions with anatomical transitions. The question arises whether and how these techniques can be adopted for routine diagnostic imaging.
Narrative review with an educational focus based on current literature research and practical experiences of different professions involved (physicians, MRI technologists/radiographers, physics/biomedical engineering). Different hardware manufacturers are considered.
Compressed sensing and simultaneous multi-slice imaging are novel acceleration techniques with different yet complimentary applications. They do not suffer from classical signal-to-noise-ratio penalties. Combining 3 D and acceleration techniques facilitates new broader examination protocols, particularly for clinical brain imaging. In further regions of the nervous systems mainly specific applications appear to benefit from recent technological improvements.
· New acceleration techniques allow for faster or higher resolution examinations.. · New brain imaging approaches have evolved, including more universal examination protocols.. · Other regions of the nervous system are dominated by targeted applications of recently introduced MRI techniques..

最近引入的 MRI 技术可在保持相同检查时长的情况下实现加速检查或提高分辨率。还有一些技术可在解剖结构过渡区域提供均匀的图像质量。问题是这些技术是否以及如何能够应用于常规诊断成像。
基于当前文献研究和涉及的不同专业（医师、MRI 技师/放射技师、物理/生物医学工程）的实践经验，进行了以教育为重点的叙述性综述。不同的硬件制造商都被考虑在内。
压缩感知和同时多层成像都是新的加速技术，具有不同但互补的应用。它们不会产生经典的信噪比损失。将 3D 和加速技术相结合，可以促进新的更广泛的检查方案，特别是在临床脑部成像中。在神经系统的其他区域，主要是特定的应用似乎受益于最近的技术改进。
·新的加速技术可实现更快或更高分辨率的检查。·新的脑部成像方法已经发展起来，包括更通用的检查方案。·神经系统的其他区域主要受益于最近引入的 MRI 技术的靶向应用。
