Evaluation of the estimated DWI/MTT lesion evolution scenarios. The mean dice index value (a measure quantifying the volumetric overlap between two volumes and ranges from 0 to 1 for the best match) and its standard deviation are computed over the 8 patients between the estimated and the manually delineated DWI/MTT lesions at t 2 and t 3. They are also computed for the additionally spatial deformation ϕ t1—mapping DWI lesion into MTT lesion at t 1—to show how good is the mapping of DWI lesion into MTT lesion at t 1.
| DWI(t 1) | DWI(t 3) | DWI(t 1) to MTT(t 1) | MTT(t 2) | MTT(t 3) | |
|---|---|---|---|---|---|
| Mean (dice) | 0.90 | 0.90 | 0.86 | 0.76 | 0.80 |
| SD (dice) | 0.02 | 0.02 | 0.06 | 0.09 | 0.08 |
