32 of 45 (71.1%) patients with carotid artery distribution transient ischemic attacks had normal cranial computerized tomography (CCT). 9 (20%) had cerebral atrophy. Incidental abnormalities were found in 3 (6.6%) patients, while a hypodense lesion corresponding to the site of neurological dysfunction was seen in only 1 (2.2%) patient. The latter showed a persistent abnormality in follow-up studies on the 8th and the 23rd day after the initial event. Our clinical CCT correlation did not demonstrate the frequency of hypodense lesions reported by some authors. Furthermore an increased incidence of cerebral atrophy was found compared to the one reported previously.
45例颈动脉分布区短暂性脑缺血发作患者中，32例（71.1%）头颅计算机断层扫描（CCT）正常。9例（20%）有脑萎缩。3例（6.6%）患者发现有偶然异常，而仅1例（2.2%）患者可见与神经功能障碍部位相对应的低密度病变。后者在首次发病后第8天和第23天的随访研究中显示持续异常。我们的临床CCT相关性研究未证实一些作者报道的低密度病变发生率。此外，与之前报道的相比，脑萎缩的发生率有所增加。
