最近开发的多采集与可变共振图像组合（MAVRIC）和切片编码金属伪影校正（SEMAC）技术可以显着减少图像伪影附近常见的嵌入式金属硬件。这些伪影减少是通过将替代的频谱和空间编码方案应用于传统的自旋回波成像技术来实现的。在这里，MAVRIC和SEMAC的概念连接和讨论。然后介绍了利用这两种方法的优点的混合技术的发展。所提出的技术能够产生最小的伪影，高分辨率的图像在临床环境中的全关节置换术附近。Magn Reson Med 65：71-82，2011. (c)2010 Wiley-Liss，Inc.
The recently developed multi-acquisition with variable resonance image combination (MAVRIC) and slice-encoding metal artifact correction (SEMAC) techniques can significantly reduce image artifacts commonly encountered near embedded metal hardware. These artifact reductions are enabled by applying alternative spectral and spatial-encoding schemes to conventional spin-echo imaging techniques. Here, the MAVRIC and SEMAC concepts are connected and discussed. The development of a hybrid technique that utilizes strengths of both methods is then introduced. The presented technique is shown capable of producing minimal artifact, high-resolution images near total joint replacements in a clinical setting. Magn Reson Med 65:71-82, 2011.
