ABSTRACT
Objective To study the effects of the different phases of breast dynamic contrast enhanced MR with 3D MIP in reconstruction of breast vascular.To explore the reconstruction parameters of breast vascular in benign and malignant breast lesions.Methods All of 132 female patients with pathologically confirmed breast disease were enrolled,including 50 cases of benign lesions and 82 malignant cases.All of them underwent high temporal resolution dynamic enhanced MR scanning,with each phase of 20 s.All of the images were reconstructed by 3D MIP and analyzed.Results In both of benign and malignant lesions,the display rate of the internal thoracic artery was higher than that of the lateral thoracic artery and intercostal artery.The display rate of grade Ⅱ vessels of internal thoracic artery and intercostal artery were higher in malignant lesion(P=0.035,0.000).The grade Ⅰ and Ⅱ vessels of the internal thoracic artery and the lateral thoracic artery increased gradually with time delay.The vascular branches were showed in malignant lesions earlier than those in benign lesions,in the 20th seconds in which grade Ⅰ vessels could be displayed,and in the 60th seconds,internal thoracic artery in malignant lesions(96.3%)can be clearly displayed.For benign lesions,grade Ⅰ branch of the internal thoracic artery in patients(80%)could be displayed in the 120th seconds.Conclusion Breast dynamic contrast enhanced MR with 3D MIP can be used to display the blood vessels of the breast,which is of great value in the diagnosis of breast diseases.To achieve the best display effect,different enhanced phases should be selected to reconstruct the blood vessels based on the different enhancement patterns in benign and malignant lesions.
