Abstract
Arterial spin-labeling (ASL) is a relatively new and noninvasive MR imaging technique, used to measure cerebral blood flow (CBF). Scanning time and reproducibility remain important issues in the clinical applicability of ASL. We expected both to benefit from higher field strengths. We describe that when performing ASL at 3T, 20 averages suffice to obtain steady and reproducible CBF values. Scanning time can be as short as 3 minutes.
摘要
动脉自旋标记（ASL）是一种相对较新的无创磁共振成像技术，用于测量脑血流量（CBF）。扫描时间和可重复性仍是ASL临床应用中的重要问题。我们期望两者都能从更高的场强中受益。我们描述了在3T进行ASL时，20次平均扫描就足以获得稳定且可重复的CBF值。扫描时间可短至3分钟。
