Forty patients with episodes of transient neurological dysfunction lasting less than 24 hr had abnormal CT scan findings. Eight patients had intracranial mass lesions and 32 had vascular lesions i.e. ischemic, infarction, hematoma. Seventeen patients had hypodense lesions consistent with tissue infarction; whereas 12 patients had isodense enhancing lesions consisting with tissue ischemia. In eight patients with isodense enhancing lesions, this was no neurological deterioration following carotid endarterectomy. In 3 patients who had transient ischemic attacks with CT evidence of hypodense lesions there was clinical and CT deterioration following carotid surgery.
40例短暂性神经功能障碍发作持续时间少于24小时的患者CT扫描结果异常。8例患者有颅内占位性病变，32例有血管病变，即缺血、梗死、血肿。17例患者有与组织梗死一致的低密度病变；而12例患者有与组织缺血一致的等密度强化病变。在8例有等密度强化病变的患者中，颈动脉内膜切除术后无神经功能恶化。在3例有短暂性脑缺血发作且CT有低密度病变证据的患者中，颈动脉手术后出现临床和CT恶化。
