%X 常规的扩散成像(diffusion weighted imaging, DWI)采用单e指数模型，近似地认为每个体素内的扩散为单一成分，反映了扩散的总体情况，不能反映生物组织内复杂的扩散信息。小视野成像(reduced field of view, r-FOV)和体素不相干运动(intravoxel incoherent motion , IVIM)这两种新的扩散加权成像技术在提高图像质量的同时，反映组织弥散和灌注信息，提供了乳腺肿瘤组织更多的生理病理信息。<br />
Conventional diffusion weighted imaging (DWI) uses a single e-exponential model. Approximately, the diffusion of each voxel is considered to be a single component, which reflects the overall situa-tion of diffusion and cannot reflect the complex diffusion information in biological tissues. Reduced field of view (r-FOV) and intravoxel incoherent motion (IVIM), two new diffusion-weighted imaging techniques, can improve image quality while reflecting tissue diffusion and perfusion information, providing more physiological and pathological information of breast tumor tissue.
