Table 1.
Comparison of the fracture site after healing by means of simple densitometry in computer tomography (CT) and texture analysis (TA).
| Measured Feature and Site (i.e., ROI) |
Test Group |
Reference Group |
Between-Group Difference |
|---|---|---|---|
| Optical density at the fracture site | 448 ± 122 HU 1 | 408 ± 122 HU 1 | p = 0.453 |
| Optical density in cancellous control bone | 419 ± 81 HU 1 | 384 ± 85 HU 1 | p = 0.338 |
| Sum of squares at the fracture site | 110 ± 4 2 | 108 ± 6 2 | p = 0.486 |
| Sum of squares in cancellous control bone | 97 ± 6 | 94 ± 9 | p = 0.304 |
1 Hounsfield units; 2 the observed opaque islands in the healed fracture site texture generated an increase in TA value.
