TABLE 3:
Correlation between DTI measurements and clinical scores
| Measurement | GCS Score |
Rankin Score |
||
|---|---|---|---|---|
| r Value | P Value | r Value | P Value | |
| ADC internal capsule | −0.070 | .686 | 0.018 | .914 |
| FA internal capsule* | 0.657 | <.0001 | −0.714 | <.0001 |
| ADC splenium* | 0.515 | .0015 | −0.599 | .0001 |
| FA splenium* | 0.725 | <.0001 | −0.694 | <.0001 |
| ADC thalamus | −0.165 | .342 | 0.147 | .396 |
| FA thalamus | −0.163 | .348 | 0.114 | .513 |
| ADC putamen | −0.314 | .065 | 0.280 | .103 |
| FA putamen | −0.116 | .504 | 0.187 | .281 |
Note.—Table lists the correlation coefficient r between the measured ADC and FA values and GCS or Rankin score for different anatomic locations. There proved to be a statistically significant correlation between the ADC and FA values measured within the splenium and the GCS and Rankin score, as well as between the FA value of the internal capsule and the GCS or Rankin score. The correlation between the FA values and the GCS or Rankin score was stronger than for the corresponding ADC values. A correlation probability of P < .0025 indicates a statistically significantly correlation between the measured ADC- and FA-values and the GCS/Rankin score.
