ABSTRACT
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 ran-domly 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, dif-ferent massage time showed significant statistically different SLN imaging time(P<0. 05). Conclusion In clinical work, IMRL with a con-trast agent injection dose of 0. 5 mL/person, local massage 1 min after injection can successfully achieve the lymphatic system image of breast cancer.
