Quantitative Evaluation of Temporal Regularizers in Compressed Sensing Dynamic Contrast Enhanced MRI of the Breast

Figure 7

Boxplots of CCCs and tumor means over 200 different sampling patterns. In the first two boxes, the results of the five temporal regularizers are statistically different from each other except the ones between TV and . We can observe TV and yielded the highest CCCs, which is an illustration of Table 2. In the last two boxes, the red horizontal lines indicate the true tumor mean and , which are 0.425 and 0.635, respectively. Consistent with the results in Table 2, TV and produced the most accurate tumor mean and compared to the true values. Interestingly, NN tended to greatly underestimate but accurately found on average with a slight underestimation.
