RESULTS: PAF levels in cervical cord tissue significantly increased following trauma. PAF levels were evidently elevated by arachnoid space injection of PAF. 结果:颈髓损伤后颈髓组织PAF含量明显增加、蛛网膜下腔注射PAF可使伤后PAF含量增加更为显著;
Results: 1. MC was a extradural recess in the posterior of the middle fossa, it contained subdural space, arachnoid, subarachnoid space, trigeminal ganglion, neural fibers and cerebrospinal fluid, et al; 结果:(1)MC为颅中窝后部的硬脑膜陷窝,包含硬膜下腔、蛛网膜、蛛网膜下腔、三叉神经节、神经纤维和脑脊液等结构;
Arachnoid cyst and subarachnoid space enlargement carried different curve patterns. 基于这一现象和蛛网膜囊肿与蛛网膜下腔扩大的发病机理的不同,两者的相位图、流量曲线图以及时间-信号强度曲线图均有明显差异,各有其特征性。
Purpose: To evaluate the diagnostic value of phase-contrast cine MRI in differentiating arachnoid cyst from subarachnoid space enlargement and ascertaining the communication between cyst and the neighboring cistern. 目的:评价磁共振相位对比电影法在蛛网膜囊肿与蛛网膜下腔扩大及囊肿与邻近脑池是否相通的诊断价值。
Differential Diagnosis of Arachnoid Cyst with Subarachnoid Space Enlargement with Phase-Contrast Cine MRI 磁共振相位对比电影对蛛网膜囊肿与蛛网膜下腔扩大的鉴别诊断
