婴幼儿运动发育迟缓的颅内常规MRI评估

目的:探讨112例经Gesell法评估为运动发育迟缓婴幼儿的常规头颅MRI表现。方法:常规头部MRI扫描,采用FSE行头颅轴位T1WI和T2WI、冠状位T2FLAIR和矢状位T1WI平扫,进行影像学分析评估。结果:脑白质髓鞘化异常占30.4%(34/112),脑外间隙和脑室增宽占19.6%(22/112),缺氧缺血性脑病后遗改变占17.9%(20/112),脑发育异常占17.0%(19/112);MRI平扫未见异常占15.2%(17/112)。结论:头颅常规MRI扫描是诊断婴幼儿运动发育迟缓的重要方法,在早期诊断、评估及预后追踪方面有重要意义。

The routine cranial MRI evaluation of motor delay in infants

Objective： The purpose of this study was to review MRI features of motor delay in infants in 112 patients which were clinical diagnosed by the Gesell＇s movement evaluating method. Methods： 112 patients were taken in routine cranial MRI scan. They were performed with SE pulse sequence in axial T1WI and T2 WI,T2 FLAIR,coronal T2WI and sagittal T1 WI with- out contrast enhancement. To analyse and to evaluate the MRI signs of these patients. Results： There were 30. 4% abnormity myelination of cerebral white matter cases （34/112）, 19.6%enlargement of extracerebral space and ventricle cases （ 22/112 ）, 17.9% sequelaes of hypoxic-ischemie encephalopathy cases （22/112）, 17. O% cerebral dysplasia cases （19/112） ,and 15.2% negative of scan cases （17/112） in all of them. Conclusion：The routine cranial MRI scan is an important method which in diagnosing motor delay in infants. It is a credible approach of early diagnosis, evaluation and following up the prognosis for the disease.
