脑囊虫病磁共振成像分析

本文报告３４例脑囊虫病患者的磁共振成像（ＭＲＩ）表现。其中脑实质型２６例，脑室型６例，混合型２例。脑实质型中７例为单发病灶，６例为多发病灶，其余１３例为数量较多的多发病灶。此型ＭＲＩ表现常为小的长Ｔ＿１低信号与长Ｔ＿２高信号囊肿。脑室型显示脑室扩大，可见脑室内囊肿壁，有３例可见头节。１６例ＭＲＩ与ＣＴ作了对比分析，对于病变大小、范围、数目及部位的显示，ＭＲＩ均优于ＣＴ，特别是微小病灶。

ANALYSIS OF THE MR IMAGING IN FHE CEREBRAL CYSTICERCOSIS

The MR imaging diagnosis of 34 patients with cerebral cysticercosis was reportedin this parer. Out of the 34 patients , 26 cases were cerebral parenchyma type, 6 cases brain ven-tricle type, 2 cases mixed type. Of the cases with cerebral parenchyma type,7 cases had singlefocus,6 cases had scored and hundreds multiple foci, The other l3 cases had multiple foci.Thismultiple foci type MRI usually were smaller long T_1 low intensity signal and long T_2 high signalcyst. Brain ventricle type showed brain ventricles enlarged , in 3 cases scolex can be seen. The re-sults of MRIand CT of l6 cases with cerebral cysticercosis have been compared and analysed.It isbelieved that the MRl was superior to CT in determining the size, scope, number and localizationof the lesions.
