Outline of Final Research Achievements

The CSA of the cervical nerve root was measured at the affected level and the contralateral side in CR patients. The difference between the affected and the unaffected side (ΔCSA) were calculated for each cervical level. In the result, the ΔCSA was also significantly larger at the affected side at the C5, C6 and C7 levels (P<.001). A receiver operating characteristic analysis demonstrated that the best threshold values were 12.2 mm2 (CSA) and for C5NR, 16 mm2 for C6NR, and 14.5 mm2 for C7NR. In conclusions, this study revealed that the CSAs of affected nerve roots were enlarged in CR patients.
As to the contrast ultrasonographic examination, a time to peak (TTP) (from intra-venous to contrast peak time) were examined between the affected and the unaffected cervical nerve root under the ultrasound. The TTP was extended at the affected cervical nerve root (14sec) more than the unaffected nerve root (19sec). We speculated that the enlarged nerve root was related to the nerve congestion.
