The characteristic findings on computed tomography (CT) in multiple sclerosis (MS) are discussed. In a series of 49 cases plain CT was normal in 21 (43%), cerebral atrophy alone was present in 17 (35%) and plaques were visible in 11 (23%). These were most often adjacent to the lateral ventricles (14 plaques) and in the parietal white matter (10 plaques). CT was performed after the intravenous administration of iodide in 16 of these cases. Three of the low attenuation and three additional isodense lesions enhanced. Two patients with low attenuation plaques were scanned with xenon enhancement; the plaques absorbed less xenon than the corresponding contralateral brain substance and additional, previously isodense plaques were revealed. In one case the white matter absorbed much less xenon than normal and its uptake relative to grey matter was reduced.
本文讨论了多发性硬化症（MS）在计算机断层扫描（CT）上的特征性表现。在一组49例病例中，21例（43%）平扫CT正常，17例（35%）仅有脑萎缩，11例（23%）可见斑块。这些斑块最常位于侧脑室旁（14个斑块）和顶叶白质（10个斑块）。其中16例在静脉注射碘剂后进行了CT检查。3个低密度病变和另外3个等密度病变有强化。2例有低密度斑块的患者进行了氙增强扫描；斑块吸收的氙比相应的对侧脑实质少，并且发现了额外的、先前等密度的斑块。在1例病例中，白质吸收的氙比正常情况少得多，其相对于灰质的摄取减少。
