To investigate the feasibility of rice pads for improving nonuniform fat suppression in magnetic resonance imaging (MRI) of the neck, shoulder, and elbow using the chemical shift selective (CHESS) technique.
CHESS imaging of the neck, shoulder, and elbow was performed on 10 healthy volunteers with and without the use of rice pads. Images were visually assessed by one radiologist and one radiologic technologist using a four-point scale. Results were compared using Wilcoxon's signed rank sum test.
Images with and without rice pads were rated 3.9 and 1.5 for the neck (P = 0.002), 3.85 and 2.5 for the shoulder (P = 0.002), and 3.4 and 2.45 for the elbow (P = 0.004).
Fat-suppressed images obtained using the CHESS technique were significantly improved by rice pads for the neck, shoulder, and elbow, indicating that image deterioration with CHESS caused by magnetic field nonuniformity can be improved by rice pads in all body areas.
探讨使用化学位移选择（CHESS）技术的米垫在改善颈部、肩部和肘部磁共振成像（MRI）中非均匀脂肪抑制的可行性。
对 10 名健康志愿者进行了颈部、肩部和肘部的 CHESS 成像，使用和不使用米垫。由一名放射科医生和一名放射技师使用四点量表进行视觉评估。使用 Wilcoxon 符号秩和检验比较结果。
颈部有和没有米垫的图像评分为 3.9 和 1.5（P = 0.002），肩部为 3.85 和 2.5（P = 0.002），肘部为 3.4 和 2.45（P = 0.004）。
使用 CHESS 技术获得的脂肪抑制图像通过米垫在颈部、肩部和肘部得到了显著改善，表明 CHESS 引起的磁场不均匀导致的图像恶化可以通过米垫在所有身体部位得到改善。
