SNR of mouse sub-cutaneous fat tissue, kidney and limb muscle in standard bSSFP and WS-bSSFP images at 7T.

The values obtained when the frequency excitation was shifted by 166.7Hz (corresponding to 3/4TR shift with TR = 4.5ms) or not (OR) and for SOS4 reconstruction are shown.
* represents p<0.01 compared to fat SNR on standard images.
SNR of mouse sub-cutaneous fat tissue, kidney and limb muscle in standard bSSFP and WS-bSSFP images at 7T.

本研究展示了激励频率偏移166.7Hz（对应重复时间（Repetition Time, TR）=4.5ms时的3/4TR偏移）或未偏移（OR）、且采用SOS4重建算法下所获得的数值结果。
* 表示与标准图像中的脂肪信噪比（Signal-to-Noise Ratio, SNR）相比，差异具有统计学显著性（p<0.01）。
本研究同时给出了7T磁共振成像系统下，标准平衡稳态自由进动（balanced steady-state free precession, bSSFP）与加权平衡稳态自由进动（weighted balanced steady-state free precession, WS-bSSFP）图像中小鼠皮下脂肪组织、肾脏及四肢肌肉的信噪比（SNR）。
