摘　　要：目的研究对比剂注射技术对乳腺癌磁共振间质淋巴成像的影响,建立并标准化乳腺癌磁共振间质淋巴成像对比剂注射技术流程。方法将36例浸润性乳腺癌患者随机均分为4组,研究对比剂注射剂量及注射后局部按摩时间的差异对磁共振间质淋巴成像中前哨淋巴结达到最佳强化所用时间的影响,根据实验结果选择最佳对比剂注射技术方案。结果相同按摩时间下,注射不同剂量对比剂对前哨淋巴结达到最佳强化图像所用时间差异无统计学意义(P>0.05);注射相同剂量对比剂情况下,不同按摩时间对出现SLN最佳强化图像所用时间差异有统计学意义(P<0.05)。结论临床工作中采用乳晕皮内注射对比剂每人0.5 m L的剂量,注射后局部按摩1 min,可使乳腺局域淋巴系统最佳显影。Objective To study the influence of different contrast injection skills in interstitial magnetic resonance lymphography（ IMRL）of breast cancer,and standardize the IMRL contrast injection process. Methods A total of 36 patients with invasive breast cancer were randomly divided into four groups. The imaging time of different contrast agent dose and local massage time on sentinel lymph node（ SLN） were analyzed. According to the results,the best contrast injection methods technology program was choosed. Results For the same massage time,different contrast agent doses showed no significant difference in the SLN imaging time（ P 〉0. 05）; For same contrast agent dose,different massage time showed significant statistically different SLN imaging time（ P〈 0. 05）. Conclusion In clinical work,IMRL with a contrast agent injection dose of 0. 5 m L / person,local massage 1 min after injection can successfully achieve the lymphatic system image of breast cancer.
