摘　　要：目的:探讨高血压性脑出血的低场磁共振诊断价值。方法:对80例高血压性脑出血病人进行低场磁共振扫描,观察分析其病灶的形态与信号变化情况。结果:病灶主要位于两侧基底节区和丘脑,以肾形多见,在超急性期病灶即表现为高信号(T_1加权、T_2加权),信号欠均匀,随着时间的延续,病灶信号逐渐演变为外高中低信号和均匀高信号,最后呈T_1加权低信号,T_2加权高信号。其中,多发性出血占1.17％,反复性出血占6.25％。深部脑出血可破入脑室(约占12.5％)。结论:对于急性脑出血低场磁共振扫描与CT检查具有同等诊断价值。Objective: To study the clinical characteristics of hypertensive cerebral hemorrhage and the diagnosis valu of the low - field magnetism resonance imaging(MRI). Method:80 patients who suffered from hypetensive resonance sive cerebral hemorrhage were scanned by low-field MRI, then the shape and the signal changes of the focuses were observed and analysed. Results: The focuses lie in the basal ganglia of both sides and the lamic. Many focuse have the shape of ren during the super - acute stage and the focuses show the features of high signalintensity ( T1 weighted, T2 weighted ) , which are less homogeneous. As time goes on, the signals of the focuses became outwardly high but inwardly low and homogeneous with high intensity. Finally, they presented T1 weighteel signals of low intensity and T2 weighteel signals of high intensity. Of them, frequents - occurring hemorrhage accounts for 1. 17 percent and the repeatedly- occurring 6.25 percent; the hemorrhage in the depths of cerebrum which could get into ventricles (close to 12.5 percent). Conclusion:The low- field MRI is smillar to CT in the diangnosis of acute oerebral hemorrhage.
