Our objectives were to study the cerebral pathophysiology of eclampsia with the noninvasive technique of magnetic resonance imaging to compare the ability of magnetic resonance imaging to detect cerebral abnormalities in eclampsia with that of computed tomography.
Twenty-four patients with eclampsia received both magnetic resonance imaging and computed tomographic scanning.
Forty-six percent of the magnetic resonance imaging was abnormal and 33% of the computed tomography was abnormal. This higher incidence of abnormal magnetic resonance imaging scans was present in spite of the fact that they were obtained significantly longer after the patient's seizure activity. The most common abnormalities were cortisol, subcortical, and white matter edema.
Magnetic resonance imaging and computed tomographic scan abnormalities in eclampsia are usually similar. Cerebral imaging is not necessary in patients with uncomplicated eclampsia.
我们的目的是采用磁共振成像这种无创技术研究子痫的脑病理生理学，以比较磁共振成像与计算机断层扫描检测子痫脑异常的能力。
24例子痫患者接受了磁共振成像和计算机断层扫描。
46%的磁共振成像结果异常，33%的计算机断层扫描结果异常。尽管磁共振成像扫描是在患者癫痫发作活动后显著更长时间才进行的，但异常磁共振成像扫描的发生率更高。最常见的异常是皮质醇、皮质下和白质水肿。
子痫患者的磁共振成像和计算机断层扫描异常通常相似。对于无并发症的子痫患者，无需进行脑成像检查。
