中文摘要：

体素内不相干运动模型可区分多b值弥散加权成像图像中的组织微循环灌注和真实水分子扩散信息,以定量/半定量地反映组织的功能状态和显微结构特征,在乳腺肿瘤中的应用越来越广泛。尤其在乳腺癌的鉴别诊断、病理分型评估和疗效监测方面具有应用价值。

英文摘要：

Intravoxel incoherent motion model-based diffusion weighted imaging can distinguish the microcirculation reperfusion and true diffusion of water molecules,which can quantitatively or semi-quantitatively reflect the functional state and microstructure features of tissues.Thus,this technique has increasingly been used in breast tumor,especially in the differential diagnosis,pathological classification,and curative effect monitoring of breast cancer.
