Abstract
Diffusion-weighted magnetic resonance imaging (DWI) provides image contrast that is different from that obtained by conventional magnetic resonance techniques. Although previously, DWI has been used to evaluate various diseases of the central nervous system, several technical advances have expanded the clinical applications of DWI beyond the central nervous system. As a result, many reports have been published on the use of DWI in abdominal diseases. Particularly, abdominal DWI has now being focused on evaluation of patients with abdominal cancer. DWI can be used for pretreatment tumor detection, characterization including predicting tumor response to therapy, monitoring tumor response during therapy, and follow-up study after treatment to detect possible tumor recurrence.
摘要
弥散加权磁共振成像（DWI）提供了与传统磁共振技术不同的图像对比。虽然之前 DWI 已被用于评估中枢神经系统的各种疾病，但几项技术的进步已经将 DWI 的临床应用扩展到了中枢神经系统以外的领域。因此，已经有许多关于 DWI 在腹部疾病中的应用的报告。特别是，腹部 DWI 现在主要集中在评估腹部癌症患者上。DWI 可用于治疗前肿瘤检测、特征分析，包括预测肿瘤对治疗的反应、在治疗期间监测肿瘤反应以及治疗后随访研究以检测可能的肿瘤复发。
