Abstract

This study aimed to assess the feasibility for applying enhanced acceleration-selective arterial spin labeling (eAccASL) to non-electrocardiogram-gated and non-enhanced peripheral MRA. We compared eAccASL and background suppressed single shot turbo field echo (TFE)-triggered angiography non-contrast-enhanced sequence (BASS TRANCE) required electrocardiographic-gating in eight volunteers and three patients. In the volunteer study, eAccASL demonstrated a comparable arterial visualization compared with BASS TRANCE. In patient observation, the advantages with eAccASL were found in arterial visualization on the collateral vessels and without artifacts affected by arrhythmia events.

摘要

本研究旨在评估增强加速度选择动脉自旋标记（eAccASL）应用于非心电图门控和非增强外周 MRA 的可行性。我们比较了 8 名志愿者和 3 名患者中需要心电图门控的增强加速度选择动脉自旋标记（eAccASL）和背景抑制单次激发涡轮场回波（TFE）触发造影无对比序列（BASS TRANCE）。在志愿者研究中，eAccASL 显示出与 BASS TRANCE 相当的动脉可视化效果。在患者观察中，eAccASL 的优点在于能够显示侧支血管的动脉，且不存在受心律失常事件影响的伪影。
