VIBRANT动态增强MRI及其减影对乳腺癌血供的研究

Artery supply of breast cancer by using VIBRANT dynamic contrast enhanced MR imaging

目的探讨动态增强MR减影成像技术在评价乳腺癌血供中的应用价值。方法对67例乳腺癌病人分别进行乳腺VIBRANT动态增强MR检查及后处理技术,评价胸廓内、外动脉、乳腺穿支动脉及其分支的显示情况。对健侧乳腺、患侧乳腺两组血管显示进行统计学分析。结果健侧乳腺、患侧乳腺两组的胸廓内、外动脉的I级分支和乳腺穿支动脉之间的差异无显著意义(P>0.05);健侧乳腺、患侧乳腺两组的胸廓内、外动脉的II级分支之间的差异有显著意义(P<0.05)。结论乳腺动态增强MR后处理减影血管成像能够较好地显示乳腺癌的血供。

Objective：To investigate the value of dynamic contrast enhanced MR subtraction imaging in evaluation of the blood supply of breast cancer.Materials and Methods：The VIBRANT （volume imaging for breast assessment） dynamic contrast enhanced MR examination were obtained in sixty-seven patients with breast cancer,and its processed subtraction image was made to evaluate the interal and lateral thoracic artery and their branches and relationship between vessel and lesion.The showed-vascular MRI data on both normal breast and abnormal breast with lesion were statistically analyzed.Results：On normal and abnormal breast subtraction MR image,the first grade （I） branch of the interal and lateral thoracic artery and intercostal artery was no significant difference （P ﹥ 0.05） and the second garde （II） the interal and lateral thoracic artery was significant difference （P ﹤ 0.05）.Conclusion：Dynamic contrast enhanced MR and its processed subtraction image can display blood supply of breast cancer well.
