快速成像方法和用于磁共振断层扫描（MRT）所需的硬件可用性可将获取时间从大约一个小时减少到几分钟或几秒钟。随着过去20年的这种发展，磁共振成像（MRI）已成为临床诊断中最重要的工具之一。近年来，进一步提高成像速度的最大进展是平行MRI（PMRI）的发展。在过去的三年中，并行成像方法已成为商业上的，因此现在可用于广泛的临床用途。 PMRI的基本特征是扫描时间缩短，适用于几乎所有可用的MRI方法，同时保持对比度行为而无需更高的梯度系统性能。由于其更快的图像获取速度，PMRI在某些情况下甚至可以显着提高图像质量。在PMRI开发的最后十年中，已经建立了几种不同的PMRI重建方法，它们在其哲学上有部分不同，在重建方式以及在成功的图像重建方面的优势和缺点中。在这篇综述中，对当前PMRI方法在临床应用中的优势和缺点进行了简要概述，并显示了不同日常临床应用的示例。
Fast imaging methods and the availability of required hardware for magnetic resonance tomography (MRT) have significantly reduced acquisition times from about an hour down to several minutes or seconds. With this development over the last 20 years, magnetic resonance imaging (MRI) has become one of the most important instruments in clinical diagnosis. In recent years, the greatest progress in further increasing imaging speed has been the development of parallel MRI (pMRI). Within the last 3 years, parallel imaging methods have become commercially available, and therefore are now available for a broad clinical use. The basic feature of pMRI is a scan time reduction, applicable to nearly any available MRI method, while maintaining the contrast behavior without requiring higher gradient system performance. Because of its faster image acquisition, pMRI can in some cases even significantly improve image quality. In the last 10 years of pMRI development, several different pMRI reconstruction methods have been set up which partially differ in their philosophy, in the mode of reconstruction as well in their advantages and drawbacks with regard to a successful image reconstruction. In this review, a brief overview is given on the advantages and disadvantages of present pMRI methods in clinical applications, and examples from different daily clinical applications are shown.
