Fig. 4From: Chemical shift MR imaging in the lumbar vertebra: the effect of field strength, scanner vendors and flip angles in repeatability of signal intensity index measurementGraph shows SII values for each flip angle at 3.0 T Siemens MR scanner. In each box, horizontal line is the median, boundaries are 25th and 75th percentiles, straight line (bar) on each box is the range of data distribution and empty circles represent outliers (value > 1.5 box length from the 75th and 25th percentile). **: p < 0.01; ***: p < 0.001Back to article page
