Table 6:
Average correct classification rates for joint posterior fossa classifiers (3-PFT) based on shape, T2WI, and T1WI+Gd histogram/texture featuresa
| T1WI+Gd and T2WI Features | PA (%) | MB (%) | EP (%) | 3-PFT C (%) |
|---|---|---|---|---|
| ROI volume + T1WI+Gd histogram energy + T1WI+Gd sum entropy | 83.5 | 78.2 | 74.6 | 78.8 |
| ROI volume + T1WI+Gd mean + T1WI+Gd sum entropy | 80.0 | 81.9 | 69.7 | 76.4 |
| T2WI histogram skewness + T2WI mean + T2WI cluster prominence + T2WI sum variance | 76.7 | 78.1 | 71.3 | 75.2 |
Note:—3-PFT indicates 3 posterior fossa tumor; 3-PFT C, 3 posterior fossa tumor classifiers.
