脑血肿模型病理变化及MRI表现的研究

Study of Pathologic Changes and MRI Manifestations of Intracerebral Hematoma Model

采用了18个脑血肿模型进行了病理和MR成象的对照性研究。结果显示脑血肿的病理变化过程为：红细胞悬液血液浓缩、红细胞聚集血凝块形成和收缩红细胞溶解──H─S形成及低蛋白血肿液。分析认为脑血肿复杂的MRI表现是由其病理变化和血红蛋白演变共同决定的。

Pathology and MR imaging of 18 models of intracerebral hematoma (ICH) were studied con trolly. It's manifested that pathologic change process of ICH was RBC suspension──hemoconcen tration──clot formation and contraction──RBC lysis -H-S formation and lower protein liquid. It's suggested that the complicated MRI manifestations of ICH were determined by both pathologic changes and hemoglobins in it.
