T1-weighted MR images show high signal intensity in the pallidum of many patients with liver cirrhosis. The purpose of this study was to evaluate quantitative changes in MR signals in patients with liver cirrhosis by using the magnetization transfer technique.
Magnetization transfer ratios were measured in seven different regions of the brain in 37 patients with liver cirrhosis and in 37 healthy volunteers.
The magnetization transfer ratios in patients with liver cirrhosis were significantly lower than those in control subjects in the globus pallidus, putamen, thalamus, corona radiata, and subcortical white matter.
Abnormal magnetization transfer ratios may be found in otherwise normal-appearing cerebral regions.
T1加权磁共振成像显示，许多肝硬化患者的苍白球呈高信号强度。本研究旨在利用磁化传递技术评估肝硬化患者磁共振信号的定量变化。
对37例肝硬化患者和37名健康志愿者的大脑七个不同区域测量磁化传递率。
肝硬化患者苍白球、壳核、丘脑、放射冠和皮质下白质的磁化传递率显著低于对照组。
在外观正常的脑区可能发现异常的磁化传递率。
