【摘要】：RSNA2014报道的拓展MRI新技术及数据分析方法主要包括非高斯分布扩散成像模型(FROC模型)、扩散峰度成像(DKI)、酰胺质子转移成像(APT)、高分辨率敏感加权成像(HR-SWI)、化学交换饱和转移(CEST)、高分辨率磁共振成像(HRMRI)、反相-对比结合磁共振血管成像(HOP-MRA)、反转恢复超短回波时间(IR-UTE)序列等,在中枢神经系统疾病的应用研究主要包括:1鉴别高低级别胶质瘤、预测胶质瘤复发以及评价胶质瘤治疗反应;2检测缺血性卒中随时间变化特点、评估缺血半暗带、预测侧支循环及血管再通状态;3磁共振高分辨率血管壁成像观察颅内动脉粥样硬化血管壁的异常;4量化评估阿尔茨海默病脑部微结构损害、阿尔茨海默病病理性铁沉积定量;5证实帕金森病特定脑区损害、辅助帕金森病分子水平诊断;6糖尿病脑损伤的认知功能以及精神疾病功能成像。
[Abstract]:The new MRI techniques and data analysis methods reported by RSNA2014 mainly include non-#china_person0# distributed diffusion imaging model, diffusion kurtosis imaging, amide proton transfer imaging, HR-SWI, chemical exchange saturation conversion.EST, HRMRI, HOP-MRAA, IR-UTES, etc.The applied studies in central nervous system diseases mainly include identifying gliomas of high and low grade by 1: 1, predicting the recurrence of gliomas and evaluating the therapeutic response of gliomas to detect the characteristics of ischemic stroke over time, and to evaluate the ischemic penumbra.Prediction of collateral circulation and vascular recanalization Mr high-resolution wall imaging was used to evaluate the cerebral microstructural damage in patients with Alzheimer's disease by quantitative evaluation of intracranial atherosclerotic vascular wall abnormalities.Quantitative iron deposition in Alzheimer's disease confirmed the lesion of specific brain regions in Parkinson's disease and helped to diagnose cognitive and mental function of diabetic brain injury at molecular level of Parkinson's disease.
