MRI using tailored pulse sequences and gadolinium administration on high field systems has a crucial role to play in the investigation of malignant disease of the pancreatic head. Breath hold spoiled gradient echo images after gadolinium administration in the capillary phase of enhancement and fat suppressed images are particularly effective MR techniques. This review highlights specific MRI findings in a spectrum of malignant tumors of the head of the pancreas. Emphasis is given to the ability of MRI to differentiate ductal adenocarcinomas from chronic pancreatitis and islet cell tumors. Improved detection and characterization of small, non organ deforming tumors and the recent implementation of MR cholangiography are also addressed.
在高场系统上使用定制脉冲序列和注射钆对比剂进行磁共振成像（MRI），在胰头恶性疾病的检查中起着关键作用。在增强的毛细血管期注射钆对比剂后的屏气扰相梯度回波图像和脂肪抑制图像是特别有效的磁共振成像技术。这篇综述重点介绍了一系列胰头恶性肿瘤的特定MRI表现。着重强调了MRI区分导管腺癌与慢性胰腺炎和胰岛细胞瘤的能力。还讨论了对小型、非器官变形肿瘤检测和特征描述的改进，以及磁共振胰胆管造影术的最新应用。
