The diagnosis of Asperger Syndrome was based on the criteria in ICD-10 and DSM-IV. Brain magnetic resonance imaging (MRI) was performed with a 1.5 T imager. T2-weighted axial and coronal slices and T1-weighted three dimensional sagittal slices were obtained and visual and quantitative analysis ...
However, because of the lack of availability of state of the art MRI technology and expertise, echocardiography, in particular trans-esophageal echocardiogram (TEE), remains the generally accepted modality for the evaluation of cardiac anatomy and function most of the time by most practitioners. Accor...
Because of its complexity, the spine is probably the most difficult part of the skeletal system to evaluate radiologically. Improvement of computed tomography (CT) scanners and the advent of magnetic resonance imaging (MRI) have changed the approach to diagnostic imaging of the spine. Previously, ...
潜在风险包括:(1)装有心脏起搏器和ICD 的患者进行 MRI 检查时,设备内置程序可能发生意想不到的变化,如起搏器输出被抑制、不能起搏、瞬时异步起搏、快速心脏起搏、感应性心颤等;(2)起搏器或ICD 系统附近组织(特别是靠近导联端处的心脏组织)被灼伤;(3)电池过早耗尽;(4)装置完全失灵等[7]。 目前的植入式循环记...
NeuroPace of Mountain View, CA received FDA approval for MR-Conditional labeling of its RNS® implantable system for the treatment of medically refractory partial epilepsy. Unlike Cyberonics’ VNS IPGs, the RNS® neurostimulator is designed to detect abnormal electrical activity in the brain and...
Multiple sclerosis (MS) can be divided into four phenotypes based on clinical evolution. The pathophysiological boundaries of these phenotypes are unclear, limiting treatment stratification. Machine learning can identify groups with similar features usin

Brain structure in later life reflects both influences of intrinsic aging and those of lifestyle, environment and disease. We developed a deep neural network model trained on brain MRI scans of healthy people to predict “healthy” brain age. Brain regio
材料与方法收集59例年龄2~ 4岁的自闭症儿童和50名年龄4~ 10岁的正常儿童的结构磁共振数据,利用freesurfer软件提取大脑皮层厚度、灰质和白质区域体积以及从预定义的感兴趣区域(region of interest,ROI)提取的若干皮层下结构等区域特征,最后经统计分析方法计算两组的差异。 结果通过对150项脑皮层与体积指标进行 t检验组...
