| 摘 要： | 目的探讨螺旋CT对大脑中动脉供血区超急性期脑梗死的诊断价值.方法对62例大脑中动脉供血区超急性期脑梗死（发病6 h内）的CT征象进行分析.结果大脑中动脉供血区脑梗死超急性期CT表现为MCA高密度征、点状征及豆状核边缘模糊,密度减低;岛叶密度减低,相应侧裂池变窄;颞叶灰质密度减低,脑沟变窄或消失,灰白质界限不清.结论螺旋CT对大脑中动脉供血区超急性期脑梗死有很高的诊断价值.

| Abstract: | Objective To explore spiral CT diagnosis value on ultra-acute middle cerebral artery infarction. Method Clinical characteristics and CT findings were analyzed in 62 cases with ultra-acute MCA infarction within 6 hours. Results The early CT findings of MCA infarction include ultra-acute MCA sign, dot sign and lenticula edge unsharpness and low density;low density of insula, corresponding lateral cleft pool narrowing;low density of grey matter of temproral lobe, anfractuosity narrowing or disappearance and unclear grey matter margin. Conclusion Spiral CT has high diagnosis value on ultra-acute middle cerebral artery infarction. |
