血管壁磁共振成像是评估颅内动脉粥样硬化疾病的有用工具。增强可能特别有启发性。本研究调查了造影剂给药和图像采集之间的持续时间的影响。持续时间最长的队列的信号强度变化增幅最大。当使用血管壁 MR 成像评估颅内动脉粥样硬化疾病时，应设计方案以最大限度地延长造影剂给药和图像采集之间的持续时间，以最好地证明增强效果。
Vessel wall MR imaging is a useful tool for the evaluation of intracranial atherosclerotic disease. Enhancement can be particularly instructive. This study investigated the impact of the duration between contrast administration and image acquisition. The cohort with the longest duration had the greatest increase in signal intensity change. When using vessel wall MR imaging to assess intracranial atherosclerotic disease, protocols should be designed to maximize the duration between contrast administration and image acquisition to best demonstrate enhancement.
