目的 探讨磁共振扩散加权成像(DWI)在颈部淋巴结病变中的诊断价值.方法 对经病理证实20例淋巴结转移瘤、10例淋巴结结核及20例健康体检者进行常规磁共振成像(MRI)及DWI检查,测量淋巴结实性部分的表观弥散系数(ADC)并比较.结果 淋巴结转移瘤淋巴结实性部分ADC(0.842±0.156)× 10-3 mm2/s,淋巴结结核淋巴结实性部分ADC(1.249±0.142)×10-3 mm2/s,健康体检者淋巴结ADC(1.291±0.176)×10-3 mm2/s,淋巴结转移瘤淋巴结实性部分ADC低于淋巴结结核及健康体检者,差异有统计学意义(P＜0.01)；淋巴结结核及健康体检者淋巴结ADC比较差异无统计学意义(P＞0.05).结论 ADC结合常规MRI序列的特征,对于颈部淋巴结转移瘤、淋巴结结核及正常淋巴结的鉴别诊断具有临床应用价值.
目的 探討磁共振擴散加權成像(DWI)在頸部淋巴結病變中的診斷價值.方法 對經病理證實20例淋巴結轉移瘤、10例淋巴結結覈及20例健康體檢者進行常規磁共振成像(MRI)及DWI檢查,測量淋巴結實性部分的錶觀瀰散繫數(ADC)併比較.結果 淋巴結轉移瘤淋巴結實性部分ADC(0.842±0.156)× 10-3 mm2/s,淋巴結結覈淋巴結實性部分ADC(1.249±0.142)×10-3 mm2/s,健康體檢者淋巴結ADC(1.291±0.176)×10-3 mm2/s,淋巴結轉移瘤淋巴結實性部分ADC低于淋巴結結覈及健康體檢者,差異有統計學意義(P＜0.01)；淋巴結結覈及健康體檢者淋巴結ADC比較差異無統計學意義(P＞0.05).結論 ADC結閤常規MRI序列的特徵,對于頸部淋巴結轉移瘤、淋巴結結覈及正常淋巴結的鑒彆診斷具有臨床應用價值.

Objective To investigate the diagnosis of diffusion-weighted imaging (DWI) in cervical lymph nodes lesions.Methods Twenty patients with metastatic lymph node,10 patients with tuberculosis lymph node and 10 volunteers were underwent both conventional MRI and DWI,and the ADC values of lymph nodes' solid components were measured.The difference of ADC values between three kinds of lymph nodes were analyzed.Results ADC values of metastatic lymph nodes was (0.842 ± 0.156) × 10-3 mm2/s,ADC values of tuberculosis lymph nodes was (1.249 ± 0.142) × 10-3 mm2/s,and ADC values of normal lymph nodes was (1.291 ± 0.176) × 10-3 mm2/s.There was significant difference between ADC values of metastatic lymph nodes and with the two later kinds of lymph nodes (P＜ 0.01),and no difference in the two later kinds of lymph nodes (P ＞ 0.05).Conclusion ADC values with features of conventional MR is helpful for differentiate metastatic lymph node,tuberculosis lymph node and normal lymph nodes.
