对９６例自发性脑出血病人ＣＴ扫描３１３次，动态观察不同大小、部位的血肿周围低密度区变化过程，发现其严重程度、分布特点和持续时间与血肿大小、部位密切相关，并将发展过程分为超早期、进展期、高峰期和消退期四期，以指导脱水剂的使用。作者还根据ＣＴ影像变化的特点，结合血肿周围脑组织的病理生理变化，提出血肿周围低密度区既反映脑水肿，又反映周围组织的缺血灶。
The CT scan of 96 patients with spontaneous cerebral hemorrhage was performed 313 times to dynamically observe the changes of low-density area around the hematoma at different sizes and locations. The severity, distribution characteristics and duration of hematoma were closely related to the size and location of the hematoma. The development process Divided into ultra-early, advanced, peak and extinction four, to guide the use of dehydrating agent. The author also based on the characteristics of CT image changes, combined with the pathological changes of brain tissue around the hematoma, made low-density area around the hematoma not only reflects cerebral edema, but also reflects the surrounding tissue of the ischemic foci.
