摘要

目的探讨剪切波弹性成像（SWE）技术在乳腺癌患者放射性臂丛神经病变（RIBP）中的诊断价值，并分析放疗后随访时间、臂丛照射体积及照射剂量与臂丛神经弹性模量值及剪切波速度（SWV）的相关性。方法选取乳腺癌术后放疗患者84例，并根据放射性神经病变症状分级量表（LENT-SOMA量表）将所有患者分为A组（1级）45例、B组（2级）34例、C组（3级）5例；另选取同期40例健康女性作为对照组。比较各组间臂丛神经厚径、周长及横截面积的差异，并使用SWE技术测量臂丛神经弹性模量值及剪切波速度（SWV），绘制受试者工作特性曲线。记录乳腺癌患者放疗后随访时间、臂丛照射体积及照射剂量。结果各组间臂丛神经厚径、A组与对照组、B组与C组周长及横截面积相比较差异无统计学意义（P＞0.05），但B组和C组与A组和对照组相比，周长及横截面积均增大，差异有统计学意义（P＜0.05）；各组间臂丛神经弹性模量值及SWV比较差异均有统计学意义（P＜0.05），且B组和C组弹性模量值及SWV高于A组，C组弹性模量值及SWV高于B组，差异均有统计学意义（P＜0.05）。相关性分析结果显示，A、B、C三组放疗后随访时间、臂丛照射体积及照射剂量与臂丛神经弹性模量值（r=0.333、0.414、0.465，P＜0.05）、SWV（r=0.345、0.421、0.482，P＜0.05）呈正相关。结论 SWE技术可以定量评估臂丛神经弹性变化，为RIBP的早期发现、早期诊断提供影像学参考。

Abstract

Purpose To explore the diagnostic value of shear wave elastography in radiation brachial plexus neuropathy in patients with breast cancer

and to analyze the correlation between follow-up time after radiotherapy

brachial plexus radiation volume

radiation dose and brachial plexus elastic modulus and shear wave velocity. Methods According to the LENT-SOMA scale

84 patients with breast cancer were divided into group A (grade 1，n=45)

group B (grade 2，n=34) and group C (grade 3，n=5)

and 40 healthy women in the same period were selected as control group. The differences of thickness

perimeter and cross-sectional area of brachial plexus among groups were compared.The elastic modulus and shear wave velocity of brachial plexus weremeasured by SWE technique

and the ROC curve was drawn.The follow-up time after radiotherapy

brachial plexus radiation volume and radiation dose of breast cancer patients were recorded. Results There was no significant difference in the thickness of brachial plexus among the four groups

so were the difference in the perimeter and cross-sectional are between group A and control group

group B and group C(P＞0.05)

but the perimeter and cross-sectional area of brachial plexus in group B and group C were significantly higher than those in group A and control group (P＜0.05)

the difference was statistically significant.There were significant differences in brachial plexus elastic modulus and SWV among different groups.The values ofelastic modulus and SWV of brachial plexus in group B and C were significantly higher than those in group A

and the values of elastic modulus and SWV in group C were significantly higher than those in group B (P＜0.05). The results of correlation analysis showed that the follow-up time

brachial plexus radiation volume and dose in group A

B and C were positively correlated with brachial plexus elastic modulus (r = 0.333

0.414

0.465，P＜0.05) and SWV (r = 0.345

0.421

0.482 P＜0.05). Conclusion SWE technique can quantitatively evaluate the changes of brachial plexus elasticity and provideimaging reference for early detection and early diagnosis of RIBP.
