目的:探讨3． 0T 磁共振动态增强检查VIBRANT( Volume Imaging for Breast Assessment，乳腺容积成
像序列) 技术在乳腺疾病诊断中的价值。方法:回顾性分析经手术病理证实的32 例乳腺疾病病人的MRI 资料，
分析病变信号、形态、时间－信号强度曲线，计算VIBRANT 动态增强扫描技术用于诊断良恶性病变的灵敏度、特
异度、准确度。结果:采用VIBRANT 乳腺动态增强扫描技术后，在保证图像信噪比的条件下，克服了传统动态增
强检查的缺点，并且结合病变动态增强后的征象和时间－信号曲线图，明显提高了对乳腺良、恶性病变的诊断，
其诊断的敏感性为100%，特异性为81． 25%，准确性为93%。乳腺肿瘤动态增强曲线流入型与流出型( P =
0． 000) 、平台型与流出型( P = 0． 001) ，差异有统计学意义;流入型与平台型( P = 0． 209) ，差异无统计学意义。结
论: VIBRANT 动态增强扫描技术为乳腺磁共振动态增强检查提供了更新、更好的方法，对提高乳腺疾病诊断的
正确性无疑是一种更先进的技术。

Objective: To study the diagnosis value of 3． 0 T dynamic enhanced MRI VIBRANT
technique in breast diseases． Methods: A retrospective analysis of 32 patients proved by pathology of
breast disease． Analysis of lesion morphology， signal， time—signal intensity curve，calculating the sensitivity，
specificity and accuracy of dynamic enhanced MRI VIBRANT technique in the diagnosis of
breast diseases． Results: By using dynamic enhanced MRI VIBRANT technique， the sensitivity of diagnosis
was 100%， the specificity of diagnosis was 81． 25% and the accuracy of diagnosis was 93%． About
dynamic enhancement curve， the differences of inflow and outflow type was statistically significant
( P = 0． 000) ，and the differences of platform and outflow type was statistically significant( P = 0． 001) ，
the differences of inflow and platform type was not statistically significant( P = 0． 209) ． Conclusion:
Dynamic enhanced MRI VIBRANT technique could improve the diagnosis of breast diseases．
