目的 探讨磁共振全身弥散加权成像(WB-DWI)诊断乳腺癌淋巴结转移的应用价值.方法 筛选乳腺癌淋巴结转移患者21例和健康志愿者26例的全身弥散加权成像资料进行分析.把全身淋巴结转移部位分为颈部、两侧腋窝、锁骨上下区、纵隔、肺门、腹腔、腹膜后、盆腔8个区域,根据淋巴结短径的大小分为(≤ 1.0 cm、1.0 cm ~ 1.5 cm、1.5 cm ~ 2.0 cm、≥ 2.0 cm)四组.测量转移淋巴结、正常淋巴结的ADC值并进行分析;把WB-DWI诊断的转移淋巴结与临床确诊的转移淋巴结进行对比分析,得出WB-DWI诊断不同部位、不同短径组转移淋巴结的准确率.结果 在b = 800 s/mm2的图像中,转移淋巴结与正常淋巴结间的ADC值差异具有统计学意义(P< 0.05),不同短径组之间转移淋巴结的ADC值差异无统计学意义(P> 0.05).WB-DWI诊断乳腺癌淋巴结转移的平均准确率达94.3﹪,能够满足临床诊断要求.结论 WB-DWI通过淋巴结信号的改变及ADC值的测量,诊断乳腺癌淋巴结转移具有明显优势.
目的 探討磁共振全身瀰散加權成像(WB-DWI)診斷乳腺癌淋巴結轉移的應用價值.方法 篩選乳腺癌淋巴結轉移患者21例和健康誌願者26例的全身瀰散加權成像資料進行分析.把全身淋巴結轉移部位分為頸部、兩側腋窩、鎖骨上下區、縱隔、肺門、腹腔、腹膜後、盆腔8箇區域,根據淋巴結短徑的大小分為(≤ 1.0 cm、1.0 cm ~ 1.5 cm、1.5 cm ~ 2.0 cm、≥ 2.0 cm)四組.測量轉移淋巴結、正常淋巴結的ADC值併進行分析;把WB-DWI診斷的轉移淋巴結與臨床確診的轉移淋巴結進行對比分析,得齣WB-DWI診斷不同部位、不同短徑組轉移淋巴結的準確率.結果 在b = 800 s/mm2的圖像中,轉移淋巴結與正常淋巴結間的ADC值差異具有統計學意義(P< 0.05),不同短徑組之間轉移淋巴結的ADC值差異無統計學意義(P> 0.05).WB-DWI診斷乳腺癌淋巴結轉移的平均準確率達94.3﹪,能夠滿足臨床診斷要求.結論 WB-DWI通過淋巴結信號的改變及ADC值的測量,診斷乳腺癌淋巴結轉移具有明顯優勢.

Objective To investigate the clinical value of using whole body diffusion weighted imaging (WB-DWI)in the diagnosis of the lymph-node metastasis of breast cancer.Methods 26 healthy volunteers and 21 breast cancer patients with metastatic lymph nodes were scanned using WB-DWI. Lymph node metastasis were divided into eight groups according to the location, including cervical part, axillary fossa, clavicular region, mediastinum, hilum of lung, peritoneal cavity, retroperitoneal area and cavitas pelvis. At the same time all metastatic lymph nodes were divided into four groups according to short diameter of lymph node as ≤ 1.0 cm, 1.0 cm- 1.5 cm, 1.5 cm- 2.0 cm, ≥ 2.0 cm. The ADC value between metastatic lymph nodes and normal lymph nodes were compared and the results were compared with the clinical diagnosis. The accuracy was calculated in each regions and shortest diameter groups.Results In the imaging of b = 800 s/mm2, the difference of the ADC value between metastatic and normal lymph nodes was statistically significant(P < 0.05). The differences of the ADC values between metastatic lymph nodes of different shortest diameter were not statistically significant(P >0.05). The accuracy of metastatic lymph node reached to 94.3﹪ which was high enough for clinical applications. Conclusions WB-DWI has been shown as a promising technique for the diagnosis of metastatic lymph nodes.
