摘要

目的：

通过磁共振动态增强扫描技术观察单侧乳腺癌病变对双侧胸廓内动脉（internal thoracic artery，ITA）的影响。

方法：

156例患者首次行乳腺磁共振动态增强检查，选取动脉期时相的相应图像，测量并计算双侧ITA的平均内径，进行统计学分析。

结果：

正常对照组69例，右乳癌组44例，左乳癌组43例。正常对照组左、右ITA内径差异无统计学意义。乳腺癌组左、右ITA内径均较正常对照组增大，且无论病灶位于哪侧乳腺，右侧ITA内径增大程度较左侧明显，差异有统计学意义（

0.05）。

结论：

单侧乳腺癌病变会导致双侧ITA不同程度扩张， ITA及其分支可能是乳腺癌病变的主要供血动脉。

Abstract

Objective:

To observe the effect of unilateral breast cancer on bilateral internal thoracic artery (ITA) by using dynamic contrast-enhanced MRI.

Methods:

A total of 156 patients underwent dynamic contrast-enhanced MRI for the first time. The images of the arterial phase were selected and the average inner diameters of bilateral ITAs were measured and calculated.

Results:

There were 69 cases in the control group

44 cases in the right breast cancer group and 43 cases in the left breast cancer group. There was no significant difference in internal diameters of left and right ITAs in the control group. The diameters of left and right ITAs in the breast cancer group were significantly higher than those in the control group. No matter which side of the b

reast the lesions located

the diameter of right ITA was significantly increased than that of left ITA (

0.05).

Conclusion:

Unilateral breast cancer may lead to bilateral ITA expansion in different degrees. ITA and its branches may be the main supplying artery of breast cancer.
