Normalized saliency maps for the best selected features for each region of interest and image type highlight the areas with the highest feature values: (A) T1w GLCM cluster shade in WM, (B) PD first-order skewness in WM, (C) MT first-order minimum in WM, (D) R1 first-order kurtosis in WM, (E) R2* GLCM cluster shade in WM, (F) T1w GLCM cluster shade in NAWM, (G) PD GLDM large dependence high gray level emphasis in NAWM, (H) MT GLDM large dependence high gray level emphasis in NAWM, (I) R1 first-order 10-percentile in NAWM, (J) R2* GLCM Imc2 in NAWM, (K) T1w first-order 10-percentile in GM, (L) PD first-order 10-percentile in GM, (M) MT GLDM small dependence low gray level emphasis in GM, (N) R1 first-order minimum in GM, and (O) R2* GLDM low gray level emphasis in GM.

(A) The first-order Floquet sideband amplitude follows a 1/ν_ac dependence with the driving frequency ν_ac. The result of fit is ξ = 0.017/ν_ac; B_ac = 2.25 nT. (B) The first-order Floquet sideband amplitude follows a linear dependence with the driving amplitude B_ac. The fit result is ξ = 0.0055 B_ac + 0.0096, where ν_ac = 1.000 Hz. (C) Measured magnetic sensitivity of the maser-based magnetometer (note that the vertical and horizontal axes have a logarithmic scale).

Shapley additive explanations (SHAP) dependence plot of the features in the model. Each point on the plot corresponds to a prediction in a patient. (a) Dependence plot of shape sphericity shows how SHAP values vary with varying sphericity and the interaction with overall staging. (b) Dependence plot shows how SHAP values vary with contrast-enhanced T1-weighted first-order mean absolute deviation and the interaction with overall staging. (c) Dependence plot shows how SHAP values vary with overall staging and the interaction with shape sphericity. (d) Dependence plot shows how SHAP values vary with overall staging and the interaction with contrast-enhanced T1-weighted first-order mean absolute deviation.
