The aim of this study is to demonstrate the accuracy of MRI and MR angiography, using 3D and 2D TOF sequences to diagnose vascular malformation in children with non-traumatic intracranial hemorrhage (subarachnoid or intracerebral hemorrhage).
In two years period 7 children, 4 boys and 3 girls range age 8 to 14 years with non-traumatic intracranial hemorrhage were examined on 1.0 TMR unit, using T1,PD,T2 WI and 3D and 2D TOF MR angiography with MIP reconstruction.
In the group of 7 children, 2 were with aneurysms, 2 with AV malformation, and 1 with cavernous angioma. The results of these were correlated with those of IA DSA. The results were in agreement regarding the presence, location and size of aneurysms, the presence, vasculation and drenage of AV malformation.
MRI with MR angiography is rapid and non-invasive examination which can confirm the diagnosis of vascular anomalies in children and to follow them up.
本研究的目的是通过使用三维和二维时间飞跃（TOF）序列的磁共振成像（MRI）和磁共振血管造影（MRA）来证明其诊断非创伤性颅内出血（蛛网膜下腔或脑内出血）患儿血管畸形的准确性。
在两年期间，对7名年龄在8至14岁的非创伤性颅内出血患儿进行了检查，其中4名男孩，3名女孩，使用1.0T磁共振成像设备，采用T1、质子密度加权成像（PDWI）、T2加权成像（T2WI）以及三维和二维时间飞跃磁共振血管造影并进行最大密度投影（MIP）重建。
在这7名患儿中，2例患有动脉瘤，2例患有动静脉畸形，1例患有海绵状血管瘤。这些结果与数字减影血管造影（IA DSA）的结果相关。在动脉瘤的存在、位置和大小，动静脉畸形的存在、血管分布和引流方面，结果是一致的。
MRI联合MRA是一种快速且无创的检查方法，可用于确诊儿童血管异常并对其进行随访。
