The effect of infusion of iodinated contrast material on the enhancement of the computed tomography were studied in several kinds of the intracranial lesions. Especially, relationship between the degree of the enhancement and the time interval after the infusion was examined. It was found that the appearance of the enhancement effect were different according to the pathological types of the lesions. There were also time differences even in the same lesion before the full size of the lesions was demonstrated. The pathological type of the lesions could be suggested from the enhanced figures of the lesions, but the diagnosis would be more accurate in consideration of the localization of the lesions. It was thus concluded that this method was useful for the detection of the precise localization and the size of the lesions which were not so clearly demonstrated in conventional cranial computed tomography.
研究了碘化造影剂注入对几种颅内病变计算机断层扫描增强效果的影响。特别检查了增强程度与注入后时间间隔之间的关系。发现增强效果的出现因病变的病理类型而异。即使在同一病变中，在病变充分显影之前也存在时间差异。可以从病变的增强图像推测病变的病理类型，但考虑到病变的定位，诊断会更准确。因此得出结论，该方法有助于检测在传统头颅计算机断层扫描中显示不那么清晰的病变的精确位置和大小。
