本研究旨在探讨受累颈神经根（NR）横截面积（CSA）差异诊断颈神经根病（CR）的准确性。共对102名CR患者和219名健康志愿者进行了超声检查。由超声技术人员在盲法下测量CR患者患侧和对侧各节段颈NR的CSA。计算CR患者与正常志愿者的CSA之间的差异以及每个颈椎节段的CSA偏侧性差异（Δ CSA）。在C5、C6和C7水平，CR组受累NRs的CSA显著大于CR组未受累NRs和对照组（P <0.005）。CR组各节段的Δ CSA也明显大于CR组（P <0.001）。受试者操作特征分析表明，C5 NR的阈值为9.6 mm 2（CSA），C6 NR和C7 NR的阈值均为15 mm 2。本研究显示，受影响的NR的CSA扩大，CR患者的CSA偏侧性（Δ CSA）大于对照组患者。·通过超声测量CSA诊断颈椎神经根病。·受累神经根的CSA显著增大。CR组的Δ CSA显著高于对照组。·确定诊断CSA和Δ CSA阈值。
This study investigated the diagnostic accuracy of the difference in the cross-sectional areas (CSAs) of affected cervical nerve roots (NRs) for diagnosing cervical radiculopathy (CR). In total, 102 CR patients and 219 healthy volunteers were examined with ultrasound. The CSA of the cervical NR at each level was measured on the affected side and the contralateral side in CR patients by blinded ultrasonographic technicians. The difference between the CSAs of CR patients and normal volunteers and the difference in the laterality of CSA at the same affected level (ΔCSA) were calculated for each cervical level. The CSAs of the affected NRs in CR patients were significantly larger than those of the unaffected NRs in CR patients and those of the control group at the C5, C6 and C7 levels (P<0.005). ΔCSA was also significantly larger in the CR group at all levels (P<0.001). A receiver operating characteristic analysis demonstrated that the threshold values were 9.6 mm2 (CSA) for C5NR and 15 mm2 for both C6NR and C7NR. This study revealed that the CSAs of affected NRs were enlarged and that the laterality of the CSA (ΔCSA) was greater in CR patients than in control patients. • Cervical radiculopathy is diagnosed through ultrasonographic measurement of the CSAs. • The CSAs of affected nerve roots were significantly enlarged. • The ΔCSA in the CR group was significantly higher than in the control group. • Diagnostic CSA and ΔCSA thresholds were identified.
