目的：利用弥散张量纤维束成像（DTT）观察动静脉畸形（AVM）患者的皮质脊髓束（CST），并确认 DTT 在 AVM 患者中的临床可靠性。方法：我们对 24 名 AVM 位于 CST 附近的患者进行了 DTT。同时显示束和 AVM，提供有关它们空间关系的信息。我们还在 AVM 水平上计算了 DTT-CST 中的体素数量。结果：23 名患者观察到 DTT。所有9例偏瘫患者的DTT-CST均累及AVM或其周围病变。与对侧相比，患侧 DTT-CST 体积显着减少（P = 0.0469）。 14例DTT-CST无病变的患者均无偏瘫。结论 DTT治疗AVMs安全且具有临床应用价值。当 AVM 位于皮质脊髓束附近时，建议进行 DTT。
Objective: To visualize the corticospinal tract (CST) in patients with arteriovenous malformations (AVMs) by using diffusion tensor tractography (DTT) and to confirm the clinical reliability of DTT in patients with AVMs. Methods: We performed DTT in 24 patients who had their AVMs near the CST. Tracts and AVMs were shown simultaneously, providing information on their spatial relationships. We also counted numbers of voxels in the DTT-CST at the level of the AVM. Results: DTT was visualized in 23 patients. In all 9 patients with hemiparesis, their DTT-CSTs were involved in the AVM or its surrounding lesion. Their volume of DTT-CST at the affected side was significantly decreased when compared with the contralateral side (P = 0.0469). All 14 patients whose DTT-CSTs were free from lesion had no hemiparesis. Conclusions DTT was safe and clinically applicable in patients with AVMs. DTT is recommended when an AVM is located near the corticospinal tract.
