PurposeTo调查的实用方法，实现常规的同时二维MRI的多个动物在大口径实验scanners.Materials和MethodsThree四元件阵列几何形状进行了比较，对一个标准的单线圈配置方面的图像质量，易用性，和数据效率，使用四通道，4.7T小动物成像系统。结果容积共振器的线性排列允许无障碍的动物准备和使用几乎相同的成像协议单线圈配置，而无需任何图像校正或其他额外的后处理。由此产生的体内图像是视觉上无法区分的，从那些通过单线圈configuration.ConclusionThe采用2D MRI技术的动物研究的效率可以大大提高通过使用线性阵列的市售谐振器。J.磁共振成像2007;26：1162-1166.© 2007 Wiley利斯公司
PurposeTo investigate practical methods for achieving routine simultaneous 2D MRI of multiple animals in large‐bore experimental scanners.Materials and MethodsThree four‐element array geometries were compared against a standard single‐coil configuration in terms of image quality, ease of use, and data efficiency using a four‐channel, 4.7 T small animal imaging system.ResultsA linear arrangement of volume resonators permits unobstructed animal preparation and use of an imaging protocol that is almost identical to the single‐coil configuration without requiring any image correction or other additional postprocessing. Resulting in vivo images were visually indistinguishable from those acquired through the single‐coil configuration.ConclusionThe efficiency of animal studies employing 2D MRI techniques can be substantially improved by using a linear array of commercially available resonators.
