Abstract: Objective Make a scientific approach to the validity of 3D-VIBE MRI on breast tumor's evaluation.Methods 141 breast processes were examined by 3D Dynamic scanning technique with high speed and resolution, Compared with postop pathological appearance, the diagnosis of breast tumor, the ductal carcinoma in situ, their circumscriptions, and axillary lymph node metastasis were evaluated. Results The coincidence of tumor existence diagnosis was 97.2 ％(137/141). The accuracy, sensitivity and specificity of progression in duct were 69.4 ％(93/134), 75 ％(100/134), 57.1％(77/134), respectively.The accuracy,sensitivity and specificity of axillary lymph node metastasis were 92.5 ％(124/134), 53.8 ％(72/134), and 96.7 ％(129/134) respectively. Conclusion The reconstruction images through 3D Dynamic scanning technique with high speed and resolution could discover minute breast tumor and the extent of axillary lymph node metastasis around breast,and the extent of diseases in duct can also be effectively evalnated.
