From the group of patients with clinically manifested closed head injuries, patients with minimal traumatic lesions in the brain parenchyma, were separated and in addition radiographically analyzed. There were 22 patients in the group. On plain CT scans they had foci 5 to 10 mm large caused by trauma. CT is suitable investigation technique for detecting minimal traumatic brain lesions. Besides, CT is suitable for the follow up of the lesion evolution dynamics, which comprises not only changes in the lesions density but also the possibility of registering primarily reversible but macroscopically (invisible) lesions into (visible) reversible lesions on the control scans. The finding of only one or two minimal lesions in critical locations in the "inner cerebral trauma" always indicated the existence of possible lesions in other locations within the known pattern of the ICT. Minimal traumatic lesions of the brain frequently occur in ICT or in all cases where the acceleration of traumatizing forces has anteroposterior or postero-anterior course of direction. Their recognition by neuroimaging methods is of great importance due to the central localization of the foci, which otherwise cannot be detected by other methods.
从临床表现为闭合性颅脑损伤的患者群体中,分离出脑实质创伤性病变最小的患者,并进行了影像学分析。该组有22例患者。在普通CT扫描中,他们有由创伤引起的5至10毫米大小的病灶。CT是检测最小创伤性脑损伤的合适检查技术。此外,CT适用于病变演变动态的随访,这不仅包括病变密度的变化,还包括在对照扫描中将最初可逆但宏观上(不可见)的病变记录为(可见)可逆病变的可能性。在“脑内创伤”的关键位置仅发现一两个最小病变,总是表明在已知的脑内创伤模式内的其他位置可能存在病变。脑的最小创伤性病变经常发生在脑内创伤中或在所有致伤力加速度具有前后或后前方向的情况下。由于病灶的中心定位,通过神经影像学方法对其进行识别非常重要,否则其他方法无法检测到这些病灶。
