Intracranial vessel wall imaging (IVWI) is an advanced MR imaging technique that allows for direct visualization of the walls of intracranial blood vessels and detection of subtle pathologic vessel wall changes before they become apparent on conventional luminal imaging. When performed correctly, IVWI can increase diagnostic confidence, aid in the differentiation of intracranial vasculopathies, and assist in patient risk stratification and prognostication. This review covers the essential technical underpinnings of IVWI and presents emerging clinical research highlighting its utility for the evaluation of multiple intracranial vascular pathologies.
颅内血管壁成像（IVWI）是一种先进的磁共振成像技术，可直接观察颅内血管壁，并在常规管腔成像上明显显示之前检测到细微的病理血管壁变化。正确进行 IVWI 可以增加诊断信心，有助于区分颅内血管病变，并有助于患者风险分层和预后评估。本综述涵盖了 IVWI 的基本技术基础，并介绍了新兴的临床研究，强调了其在评估多种颅内血管病变中的应用。
