磁共振扩散加权成像在胰腺癌诊断中的应用

Application of Diffusion Weighted Imaging in the Diagnosis of Pancreatic Cancer

胰腺癌是最主要的胰腺肿瘤,其5年生存率不足5%,早期发现、有效评估及采取恰当的治疗十分关键。自1984年磁共振扩散加权成像(diffusion weighted imaging,DWI)首次被报道以来,其临床研究和应用价值日益凸显。DWI作为磁共振成像检查序列之一,为胰腺癌的诊断、鉴别诊断及治疗效果评价等提供重要信息。本文对DWI技术及其在胰腺癌中的应用进行综述。

Pancreatic cancer is the most common pancreatic tumor,with a 5-year survival rate of less than 5%. Therefore,early detection,effective evaluation and appropriate treatment are critical to the disease.Since diffusion weighted imaging( DWI) was first reported in 1984,it has become more and more important in clinical research and applications. As part of the sequence of magnetic resonance imaging,DWI provides important information for the diagnosis and differential diagnosis of pancreatic cancer,as well as for the evaluation of therapeutic effects. This article reviews the technology of DWI and its application in the diagnosis of pancreatic cancer.
