Abstract:
Objective:To investigate the effect of breast density on the application of MRI in preoperative diagnosis of invasive lobular carcinoma.Methods:Seventy-five patients with stage I-Ⅲ ILC who underwent MRI examination within 30 days before surgery were included in this study.Breast density was evaluated based on gland content.Tumor size was measured under MRI，and its consistency with pathological size was compared.Results:Of the 75 enrolled patients，26 cases（34.7%) found new suspicious lesions through MRI evaluation，and 20 cases（26.7%) changed the surgical methods.The detection rate of additional lesions in high density breast type patients was significantly higher than that in low density breast type patients（51.6% vs 22.7%，P=0.010).MRI evaluation of tumor size was easily underestimated in patients with low density breast type（36.4% vs 12.9%，P=0.024) and overestimated in patients with high density breast type（6.8% vs 29.0%，P=0.010)，but there was no significant difference in the proportion of size consistency between the two groups.Conclusion:Preoperative breast MRI in ILC patients can improve the detection rate of additional malignant tumors，and breast density is an important factor affecting MRI evaluation.
