扩散加权成像（DWI）技术具有无创、高效、操作简便等优势，能反映活体组织细胞内水分子的扩散特性，通过测定表观扩散系数（ADC）值大小，可获得组织内病理、生理信息，进而对组织结构及功能状态进行无创诊断。 DWI结合常规MRI影像可提高膀胱肿瘤早期诊断、临床分期、鉴别复发与放化疗炎症反应、放化疗疗效评价的准确性和特异性，在膀胱肿瘤治疗策略的选择和优化中具有重要价值。

Diffusion weighted imaging (DWI) is a kind of noninvasive, efficient and convenient technology which could evaluate the diffusion of water molecule in vivo. Apparent diffusion coefficient (ADC) calculated from DWI raw data can reflect pathological and physiological information, and can help us to noninvasively evaluate the organizational structure and functional state. DWI plays an important role in planning treatment strategies in bladder carcinoma. By combining with conventional MRI imaging, it can improve the accuracies and specificities in early diagnosis, clinical stage, differentiating recurrence from inflammation associated with radiotherapy and chemotherapy, and the evaluation of cancer response to radiotherapy and chemotherapy.
