Radiographic findings in 68 patients with trigeminal neuralgia and 24 patients with hemifacial spasm are reviewed. The relative value of various radiographic diagnostic procedures is discussed. Trigeminal neuralgia and hemifacial spasm are usually caused by vascular compression of the trigeminal root entry zone and facial nerve exit zone respectively. Computed tomography (CT) of the posterior fossa is the only radiographic screening procedure required. Angiography should be reserved for patients in whom CT findings suggest an aneurysm or tumor.
回顾了68例三叉神经痛患者和24例半面痉挛患者的影像学表现。讨论了各种影像学诊断方法的相对价值。三叉神经痛和半面痉挛通常分别由三叉神经根入区和面神经出区的血管压迫引起。后颅窝计算机断层扫描（CT）是唯一需要的影像学筛查方法。血管造影应仅用于CT检查结果提示动脉瘤或肿瘤的患者。
