The visualisation of the celiac plexus using respiratory- and cardiac-triggered three-dimensional (3D) sheath inked rapid acquisition with refocused echoes imaging (SHINKEI) was evaluated. After ethical approval and written informed consent, eight volunteers (age 27 ± 5 years, mean ± standard deviation) were scanned at 1.5 and 3 T. Displacement of the celiac ganglia due to aortic pulsatility was studied on axial single-slice breath-hold balanced turbo field-echo cine sequences in five volunteers and found to be 3.0 ± 0.5 mm (left) and 3.1 ± 0.4 mm (right). Respiratory- and cardiac-triggered 3D SHINKEI images were compared to respiratory- and cardiac-triggered fat-suppressed 3D T2-weighted turbo spin-echo and respiratory-triggered 3D SHINKEI in all volunteers. Visibility of the celiac ganglia was rated by three radiologists as visible or non-visible. On 3D SHINKEI with double-triggering at 1.5 T, the left and right ganglia were seen by all observers in 7/8 and 8/8 volunteers, respectively. At 3 T, this was the case for 6/8 and 7/8 volunteers, respectively. The nerve-to-muscle signal ratio increased from 1.9 ± 0.5 on fat-suppressed 3D T2-weighted turbo spin-echo to 4.7 ± 0.8 with 3D SHINKEI. Anatomical validation was performed in a human cadaver. An expert in anatomy confirmed that the hyperintense structure visible on ex vivo 3D SHINKEI scans was the celiac plexus. In conclusion, double-triggering allowed visualisation of the celiac plexus using 3D SHINKEI at both 1.5 T and 3 T.

呼吸和心脏触发的三维鞘管通过腹部的重新聚焦回波成像（SHINKEI）进行了快速采集，以进行腹腔神经丛的磁共振神经成像。

评估了使用呼吸和心脏触发的三维（3D）鞘色墨水快速采集并通过重新聚焦回波成像（SHINKEI）进行的腹腔神经丛的可视化。在获得伦理学批准和书面知情同意后，以1.5和3 T扫描了8名志愿者（年龄27±5岁，平均±标准差）。研究了在轴向单片屏气平衡下主动脉搏动引起的腹腔神经节的移位。五个志愿者中的涡轮场回声电影序列为3.0±0.5 mm（左）和3.1±0.4 mm（右）。在所有志愿者中，将通过呼吸和心脏触发的3D SHINKEI图像与通过呼吸和心脏触发的脂肪抑制的3D T2加权涡轮自旋回波以及通过呼吸触发的3D SHINKEI进行了比较。腹腔神经节的可见性由三位放射科医生评定为可见或不可见。在1.5 T下双触发的3D SHINKEI上，所有观察者分别在7/8和8/8志愿者中看到了左和右神经节。在3 T时，分别是6/8和7/8志愿者的情况。脂肪抑制的3D T2加权涡轮自旋回波的神经信号强度从1.9±0.5增加到3D SHINKEI的4.7±0.8。解剖验证是在人类尸体上进行的。解剖学专家证实，高强度结构可见于 使用3D SHINKEI将脂肪抑制的3D T2加权涡轮自旋回波提高到4.7±0.8时为5。解剖验证是在人类尸体上进行的。解剖学专家证实，高强度结构可见于 使用3D SHINKEI将脂肪抑制的3D T2加权涡轮自旋回波提高到4.7±0.8时为5。解剖验证是在人类尸体上进行的。解剖学专家证实，高强度结构可见于离体3D SHINKEI扫描是腹腔神经丛。总之，使用3D SHINKEI在1.5 T和3 T下进行两次触发可以看到腹腔神经丛。
