The purpose of this study was to explore the value of high-detail MR imaging in the diagnosis of the Chiari II malformation. Twenty-four patients with known Chiari II malformation as diagnosed by CT scanning were evaluated with cranial MR scans. Two patients also had spine scans. The sagittal-plane images were the most informative, and abnormalities of the telencephalon, diencephalon, mesencephalon, rhomboencephalon, upper spinal cord, and mesencephalon were shown extremely well. We found MR to be an easy and accurate method for demonstrating the abnormalities of the Chiari II malformation, and it is our procedure of choice.
本研究的目的是探讨高分辨率磁共振成像在诊断Chiari II型畸形中的价值。对24例经CT扫描确诊为Chiari II型畸形的患者进行了头颅磁共振扫描评估。其中2例患者还进行了脊柱扫描。矢状面图像提供的信息最多，端脑、间脑、中脑、后脑、上脊髓和中脑的异常情况显示得非常清晰。我们发现磁共振成像（MR）是一种显示Chiari II型畸形异常情况的简便且准确的方法，是我们首选的检查方法。
