胰腺癌恶性程度高、预后差,且胰腺解剖位置深,早期诊断和鉴别诊断困难。DWI成像作为无创性检查方法,可以检测组织细胞或分子水平的生理、生化改变,为胰腺癌的诊断及鉴别诊断提供重要信息。本文对DWI成像在胰腺癌诊断及鉴别诊断中的应用和进展进行综述。
Pancreatic cancer has a high degree of malignancy, poor prognosis and deep pancreas anatomy. Early diagnosis and differential diagnosis are difficult. As a noninvasive method, DWI imaging can detect the physiological and biochemical changes at the level of cells or molecules in tissues and provide important information for the diagnosis and differential diagnosis of pancreatic cancer. This article reviews the application and progress of DWI imaging in the diagnosis and differential diagnosis of pancreatic cancer.
