Table 2.
Number of subjects with successful (PPV≥0.5), unsuccessful (PPV< 0.5), or (3) nonsignificant (no statistically significant results) detection, when using FA/MD/MK/MD_MK/MD_FA/FA_MK/iDrArK maps restricted by MK-LAI results.
| Parameter | Successful detection [No. of patients] | Unsuccessful detection [No. of patients] | Nonsignificant [No. of patients] |
|---|---|---|---|
| FA | 5 | 19 | 1 |
| MD | 7 | 16 | 2 |
| MK | 5 | 19 | 1 |
| MD_MK | 7 | 8 | 10 |
| MD_FA | 9 | 5 | 11 |
| FA_MK | 6 | 11 | 8 |
| iDrArK | 8 | 1 | 16 |
FA fractional anisotropy, MD mean diffusivity, MK mean kurtosis, iDrArK increased mean Diffusivity, reduced fractional Anisotropy, reduced mean Kurtosis, MK-LAI Lobar asymmetry index calculated from mean kurtosis values.
The row in BOLDs denotes iDrArK - the index with the highest EZ detection accuracy.
