摘　　要：目的：分析讨论脑室出血时脑室内血肿的磁共振（ＭＲＩ）信号演变．方法：应用自旋回波序列对１２例脑室出血病人进行６０例次动态头颅ＭＲＩ检查．结果：病程一周内，脑室出血在Ｔ１加权成像（Ｔ１ＷＩ）和Ｔ２加权成像（Ｔ２ＷＩ）上均呈等信号，在质子密度加权像（ＰＤＩ）上呈略高信号。一周后血肿影已完全消失．结论：脑室出血时血肿的ＭＲＩ信号演变与脑实质内出血时血肿的ＭＲＩ信号演变相似．但是，脑室出血时血肿的ＭＲＩ信号演变较脑实质内出血时血肿的ＭＲＩ信号演变快．Objective: To analyze the changes of the signal of ventricular hemorrhage at MRI. Methods: MRI was performed using spin-echo sequence with total 60 times in 12 cases with ventricular hemorrhage. Result: The equal signal was found on T1 and T2 weight image, slight high signal was found on proton dense image within the first week. The hemorrhagic signal has already disappeared at MRI after a week. Conclusion: The changes of the signal of ventricular hemorrhage couldresemble cerebtal hemorrhage. However, the former was faser than the later.
