We propose the following rules to govern the choice of local coils by the practicing radiologist: 1. Smaller coils permit smaller FOVs and better resolution. The coil should be as small as possible. 2. Match the ROS of the coil to the FOV, which will be determined by the anatomic region of interest. 3. For the case of a choice between surface coils or between a surface and a whole- or partial-volume coil, the anatomic region should lie on the high side of the crossover point. For the case of a choice among whole-volume coils, the smallest coil that surrounds the region of interest should be chosen. 4. Considerations in regard to the anatomic shape or the need to vary the position of the structure may alter the choice of coil from that obtained by S/N considerations alone.
我们提出以下规则,供执业放射科医生选择局部线圈时参考:1. 较小的线圈允许更小的视野并能提供更好的分辨率。线圈应尽可能小。2. 使线圈的接收视野(ROS)与视野(FOV)相匹配,视野将由感兴趣的解剖区域决定。3. 在表面线圈之间或表面线圈与全容积或部分容积线圈之间进行选择时,解剖区域应位于交叉点的较高一侧。在全容积线圈之间进行选择时,应选择能包围感兴趣区域的最小线圈。4. 关于解剖形状或改变结构位置的需求的考虑,可能会改变仅基于信噪比(S/N)考虑而做出的线圈选择。
