Table 3.
Dice scores (↑) of downstream anomaly detection performance based on the voxel-wise absolute differences between the diseased input and the reconstruction. The testing images include healthy T1w MRI scans with simulated pathology, and real T1w MRI images from stroke patients in ATLAS [31] dataset.
