介绍并评估一种使用全球大多数临床MRI系统可用的非集成表面线圈方法进行全身磁共振成像（MRI）的新方法。连续10例无症状受试者前瞻性接受全身MRI进行健康筛查。全身MRI包括T1、T2和弥散加权序列，并使用非集成表面线圈进行，以在不重新定位患者的情况下对四个不同的站点进行成像。合并四个单独采集的工作站，创建无缝的冠状全身T1、T2和弥散加权图像。定性评估了解剖对准、相邻工作站边界的图像质量和所有工作站的整体图像质量。将表面线圈从一个站点更换到下一个站点所需的平均时间（±SD）为53.8（±7.1）s。平均总额外检查时间± SD为2 min 41.4 s（±15.3 s）。T1、T2和弥散加权全身MRI的解剖对线、相邻站边界的图像质量以及所有站的总体图像质量总体评分为“良好”至“优秀”。这项研究表明，一个高效的时间和高质量的全身MRI检查可以很容易地通过使用非集成滑动表面线圈的方法。本文的在线版本（doi：10.1007/s 00330 -009-1674-1）包含补充材料，可供授权用户使用。
To introduce and assess a new way of performing whole-body magnetic resonance imaging (MRI) using a non-integrated surface coil approach as available on most clinical MRI systems worldwide. Ten consecutive asymptomatic subjects prospectively underwent whole-body MRI for health screening. Whole-body MRI included T1-, T2- and diffusion-weighted sequences, and was performed using a non-integrated surface coil to image four different stations without patient repositioning. The four separately acquired stations were merged, creating seamless coronal whole-body T1-, T2- and diffusion-weighted images. Anatomical alignment, image quality at the boundaries of adjacent stations, and overall image quality of all stations were qualitatively assessed. The average time (±SD) taken to change the surface coil from one station to the next station was 53.8 (±7.1) s. The average total extra examination time ± SD was 2 min 41.4 s (±15.3 s). Anatomical alignment, image quality at the boundaries of adjacent stations, and overall image quality of all stations of T1-, T2- and diffusion-weighted whole-body MRI were overall graded as “good” to “excellent”. This study shows that a time-efficient and high-quality whole-body MRI examination can easily be performed by using a non-integrated sliding surface coil approach.
