摘　　要：目的:探讨脑裂畸形的CT、MRI的影像特征。方法:回顾性分析28例脑裂畸形的CT、MRI资料,其中CT检查12例,MRI检查16例。结果:CT、MRI表现为横贯大脑半球的裂隙,裂隙壁由灰质组成。单侧型19例,双侧型9例。共有37个裂隙,融合型(Ⅰ型)15个,分离型(Ⅱ型)22个,合并其他脑先天畸形15例。结论:脑裂畸形有特征性的CT、MRI表现,并可对其分型,是目前诊断脑裂畸形最好的检查方法,且MRI优于CT。Objective To investigate the CT and MRI imaging features of Schizencephaly. Method The CT and MRI findings of Schizencephaly of 28 patients were analyzed retrospectively. 12 patients were examed with CT and 16 patients with MRI. Results The most characteristic CT and MRI findings of Schizencephaly was a transcerebral cleft which was lined by gray matte. There were unilateral clefts in 19 cases and bilateral in 9. Totally There were 37 clefts, in which 15 cleft were showed as the fused type (TYPEⅠ) and 22 cleft as the open type (TYPEⅡ).We have also found Accompanying abnormalities in 15 cases. Conclusion Schizencephaly has characteristic CT and MRI manifestations. MRI is superior to CT in classification and demonstrating those features.
