Table 2.

The 10 top scoring features. Columns 3 and 4 show the normalized relative changes Eq. (1) in feature value between the pre- and post-LITT MRIs for both residual disease and treated area. It can be seen that all selected features are related to either T2W or DCE MRI. Furthermore, texture features show larger changes in both residual disease and successfully ablated tissue; however, the relative change is similar to the pharmacokinetic features.
