ANN model’s sensitivity for the top ten most important variables, in the order of descending relative importance from left to right: (a) model 1, using spectra only; (b) model 2, using spectra and anatomical segmentation. For model 1 (a), all top ten variables originate from the Cho ppm range. For model 2 (b), the most important variable is %PZ followed by the Cho ppm intensities, which are similar to the Cho ppm positions for model 1. The overall sensitivity of model 2 is higher than the sensitivity of model 1.
