Three readers segmented tumours using freehand (FH), 40% of maximum intensity threshold (40P), and fuzzy locally adaptive Bayesian (FLAB) algorithms.
For each tumour and at each time point, readers segmented lesion contours for measurement of tumour volume, so that each of the six readers assessed all the dataset.
If Barnes & Noble doesn't go for G Asset Management's plan to take over a controlling share of the full company, the investment firm said it has another pitch: to acquire 51% of Barnes & Noble's Nook e-reader segment.

In the medial segment, readers 1 and 2 detected 18 and 17 lesions by CTAP and 7 and 9 by STIR, respectively (p = 0.01, reader 1; p = 0.035, reader 2).
If this visual validation of the nodule showed incorrect segmentation, the reader tried to segment the nodule three times with the same algorithm before concluding that the nodule could not be correctly segmented by this algorithm.
With all 17 segments and five readers, the proportions of segments with diagnostic image quality across readers was found to be 0.97 (95% CI = (0.94; 0.99)) for gadobutrol and 0.78 (95% CI = (0.70; 0.86)) for gadoterate meglumine leading to a difference of 0.19 (95% CI = (0.10; 0.10)).
