The purpose of this article is to discuss the most current techniques used for pancreatic imaging, highlighting the advantages and disadvantages of state-of-the-art and emerging pulse sequences and their application to pancreatic disease.
Given the technologic advances of the past decade, pancreatic MRI protocols have evolved. Most sequences can now be performed in one or a few breath-holds; 3D sequences with thin, contiguous slices offer improved spatial resolution; and better fat and motion suppression allow improved contrast resolution and image quality. The diagnostic potential of MRCP is now almost as good as ERCP, with pancreatic MRI as the main imaging technique to investigate biliopancreatic pain, chronic pancreatitis, and cystic pancreatic tumors at many institutions. In addition, functional information is provided with secretin-enhanced MRCP.
本文旨在讨论当前用于胰腺成像的最新技术，重点介绍最新和新兴脉冲序列的优缺点及其在胰腺疾病中的应用。
鉴于过去十年的技术进步，胰腺 MRI 方案已经发展。现在，大多数序列都可以在一次或几次呼吸暂停中完成；具有薄而连续切片的 3D 序列提供了更高的空间分辨率；更好的脂肪和运动抑制允许更高的对比度分辨率和图像质量。MRCP 的诊断潜力现在几乎与 ERCP 一样好，在许多机构中，胰腺 MRI 是用于研究胆胰疼痛、慢性胰腺炎和囊性胰腺肿瘤的主要成像技术。此外，使用促胰液素增强的 MRCP 提供了功能信息。
