Abstract

(A) CrCEST_asym MAPS OF A HUMAN CALF MUSCLE CAPTURED BEFORE AND AT 24-SECOND INTERVALS FOLLOWING 2 MINUTES OF MILD PLANTAR FLEXION EXERCISE (ARRANGED SEQUENTIALLY BY NUMBER). THE ERROR BARS INDICATE THE STANDARD DEVIATION OF CrCEST_asym WITHIN EACH MUSCLE REGION. THE SEGMENTED ANATOMICAL IMAGE IS SITUATED IN THE LOWER RIGHT CORNER. (B) PLOT ILLUSTRATING THE TEMPORAL VARIATION OF THE MEAN CrCEST_asym VALUES ACROSS THREE DISTINCT CALF MUSCLES (LG, MG, AND SOL, WHICH WERE DELINEATED FROM ANATOMICAL IMAGES (LOCATED IN THE BOTTOM RIGHT CORNER). SOLID LINES REPRESENT THE SPLINE INTERPOLATION THAT FITS THE DATA POINTS. BY CHAKRABORTY ET AL. (1681-1692)

3 T时健康志愿者小腿骨骼肌体内肌酸加权化学交换饱和转移（CrCEST） MRI的可靠性

(A)在进行2分钟轻度足底屈曲运动之前和之后每隔24秒拍摄的人小腿肌肉的肌电图（按数字顺序排列）。误差条表示在每个肌肉区域内肌痉挛的标准偏差。分割后的解剖图像位于右下角。(B)从解剖图像（位于右下角）描绘的三个不同的小腿肌肉（LG、MG和SOL）的平均肌张力值的时间变化图。实线表示拟合数据点的样条插值。chakraborty et al . （1681-1692）
