A fast spin-echo inversion-recovery (FSE-IR) sequence is described for its utility regarding surgical planning for patients with Parkinson's disease (PD) who are undergoing microelectrode-guided internal globus pallidus (GPi) ablation. Images from thirty-seven adult patients with PD were reviewed and visualization of the GPi, globus pallidus externa (GPe), and the intervening lamina was noted. High-resolution images were acquired from all patients despite the external hardware and the patients' movement disorder. In all cases, the conventional surgical trajectory, determined indirectly by a fixed measurement from the anteroposterior commissure line, was modified by the ability to visualize the GPi and optic tract directly. This sequence facilitated accurate stereotactic targeting.
本文描述了一种快速自旋回波反转恢复（FSE-IR）序列，该序列在帕金森病（PD）患者接受微电极引导的苍白球内侧核（GPi）毁损术的手术规划中具有实用价值。回顾了37例成年PD患者的图像，并观察了GPi、外侧苍白球（GPe）及其间的板层。尽管存在外部硬件和患者运动障碍，但所有患者均获得了高分辨率图像。在所有病例中，传统的手术轨迹是通过从前连合线进行固定测量间接确定的，而通过直接可视化GPi和视束的能力对其进行了修正。该序列有助于精确的立体定向靶点定位。
