目的 分析乳腺血供在乳腺良恶性病变鉴别诊断中的初步价值.方法 回顾性分析2017年2月至11月山西医科大学第二医院37例乳腺良恶性病变患者资料.在磁共振成像（MRI）最大密度投影图像上,详细记录患侧及健侧乳腺血管的数目、直径、长度及乳腺供血动脉的显示情况,并根据Sardanellie血供进行评分.以病理结果为金标准分为良性组和恶性组,依据病变最大直径的不同,将全部病例分为≥2 cm组和〈2 cm组,比较血管数目及血供评分在乳腺良恶性病变中的差别.同时依据血供评分及乳腺供血动脉情况对MRI诊断效能进行评价.结果 乳腺良性病变组患侧及健侧乳腺血管数目、Sardanellie血供评分差异无统计学意义（1.11±0.35比1.22±0.45,t=0.19,P=0.85;0.89±0.38比0.95±0.21,t=0.25,P=0.80）;乳腺恶性病变组患侧乳腺血管数目及Sardanellie血供评分高于健侧,差异有统计学意义（2.61±1.29比0.61±0.21,t=6.18,P=0.00;1.78±0.65比0.61±0.21,t=6.30,P=0.00）.乳腺恶性病变患侧血管数目及Sardanellie血供评分均高于良性病变,差异有统计学意义（t=8.57,P〈0.001;t=12.61,P〈0.001）.最大直径〈2 cm的乳腺恶性病变组患侧血管数目高于良性组,差异有统计学意义（1.27±0.59比2.57±0.98,t=90.5,P〈0.05）,而Sardanellie血供评分差异无统计学意义（1.09±0.43比1.86±0.38,t=87.0,P〉0.05）;最大直径≥2 cm的乳腺恶性病变组患侧血管数目及Sardanellie血供评分均高于良性组,差异有统计学意义（0.92±0.63比2.64±1.50,t=47.5,P〈0.05;0.92±0.33比1.73±0.79,t=53.5,P〈0.05）.病变最大直径〈2 cm的乳腺良恶性病变鉴别中Sardanellie血供评分＋乳腺供血动脉阳性并未提高MRI诊断效能;病变最大直径≥2 cm的乳腺良恶性病变鉴别中血供评分＋乳腺供血动脉阳性具有较高的诊断效能.结论 乳腺动态增强MRI可清晰显示乳腺血供情况,患侧血供增加及血供评分在乳腺良恶性病变的�
Objective To study the value of breast vascularity in differential diagnosis of benign and malignant breast lesions. Methods The data of 37 patients with benign and malignant breast lesions in the Second Hospital of Shanxi Medical University from February 2017 to November 2017 were respectively analyzed. The number, diameter, length and breast-feeding arteries of bilateral breast vessel were recorded in the maximal intensity projection （MIP） of magnetic resonance imaging （MRI） and were scored according to Sardanellie. The patients were divided into the benign group and the malignant group according to the pathological results. Besides, ≥2 cm group and 〈2 cm group was also divided according to the maximum diameter of lesions. The differences in number and score of vascularity in both groups were compared. And the diagnostic efficacy of MRI was evaluated based on Sardanellie score and breast-feeding arteries. Results There were no significant differences in the number and score of vascularity between bilateral breast in benign breast lesions group （1.11 ±0.35 vs. 1.22 ±0.45, t= 0.19, P= 0.85; 0.89 ±0.38 vs. 0.95 ±0.21, t= 0.25, P=0.80）. The number and score of vascularity of the affected side were higher than those of the healthy side in breast malignant lesions group （2.61 ±1.29 vs. 0.61 ±0.21, t= 6.18, P= 0.00; 1.78 ±0.65 vs. 0.61 ±0.21, t=6.30, P=0.00 respectively）. The number and score of vascularity were statistically different between benign and malignant breast lesions （t= 8.57, P 0.05）; The number and score of vascularity in the malignant group were higher than those in the benign group with the maximum diameter ≥2 cm （0.92±0.63 vs. 2.64±1.50, t=47.5, P〈0.05; 0.92±0.33 vs. 1.73±0.79, t=53.5, P〈 0.05）. There was no significant improvement in the diagnostic efficacy of MRI based on the score of vascularity and positive breast-feeding arteries in the identification of benign and malignant lesions when the maximum diameter of lesions were〈2 cm, and it had a high d
