摘　　要：目的探讨三维容积插值屏气检查序列（3D．VIBE）磁共振成像（MRI）检查对乳房肿瘤的诊断价值。方法采用高速、高分辨率的三维动态扫描技术对141例乳房病变进行MRI扫描，对照术后病理结果，分别对乳房肿瘤的存在性诊断、导管内癌成分的有无、范围以及腋窝淋巴结转移进行评价。结果肿瘤存在性诊断的符合率为97．2％（137／141），导管内癌成分的准确度为69．4％（93／134），敏感度为75％（100／134），特异度为57．1％（77／134）。腋窝淋巴结转移的准确度为92．5％（124／134），敏感度为53．8％（72／134），特异度为96．7％（129／134）。结论采用高速、高分辨率的3D．VIBE动态扫描后重建得到的图像能够清晰显示乳房微小肿瘤以及乳房周围淋巴结转移的程度，并能有效评估导管内病变的范围。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 evaluated.
