1足月儿缺氧缺血性脑病的常规MRI、DWI、DTI及MRS表现(英文)显示文摘近年,先进的磁共振(MR)技术和3特斯拉磁体(3T)已越来越多地被应用于新生儿,拓宽了围产期缺氧缺血性脑病(HIE)的知识。本文介绍了足月儿缺氧缺血性脑病在3T磁共振的表现,其中包括常规和先进的成像技术,如扩散加权成像(DWI),扩散张量成像(DTI)和磁共振波谱(MRS);重点强调了每种技术发现病灶的时间过程,以及与神经系统预后的关联。Yan Liu Patrice Jissendi-Tchofo Thierry Metens Julie Absil Ming Zhu Danielle Baleriaux 2011磁共振成像2011,2,1:11
2MR动态减影血管造影在脑动静脉畸形治疗前后中的评价显示文摘目的评价MR动态减影血管造影(MR-DSA)在脑动静脉畸形(AVM)栓塞治疗前后的价值和限度。方法22例AVM患者,在栓塞前后均行MR-DSA、三维增强MR血管造影(3D-CEMRA)、MR质子加权成像(PWI)和DSA检查,同时由2名有经验的医生独立进行双盲对照研究。结果MR-DSA和DSA在22例AVM栓塞前后的瘤巢大小及分类上结果一致,MR-DSA能够显示AVM栓塞后的血液动力学改变,瘤巢及引流静脉显影推迟17例,瘤巢变小13例(其中完全消失4例),与DSA符合率为100%。与DSA相比,MR-DSA没有显示瘤巢内动脉瘤和栓塞后引流静脉及供血动脉直径变小各1例,而3D-CEMRA对此显示清晰。栓塞后的PWI与栓塞前相比,22例均可见不同程度的高信号。结论MR-DSA是1种快速、有效、无创的血管造影检查方法,能提供AVM栓塞前后的血流动力学信息,MR-DSA、3D-CEMRA和PWI应在AVM的随访中相互结合,综合运用。陈爽 冯晓源 Danille Baleriaux Therry Metens 2005中华放射学杂志2005,39,10:6
3GIS-based Frequency Ratio and Logistic Regression Modelling for Landslide Susceptibility Mapping of Debre Sina Area in Central Ethiopia显示文摘Ethiopia has a mountainous landscape which can be divided into the Northwestern and Southeastern plateaus by the Main Ethiopian Rift and Afar Depression. Debre Sina area is located in Central Ethiopia along the escarpment where landslide problem is frequent due to steep slope, complex geology, rift tectonics, heavy rainfall and seismicity. In order to tackle this problem, preparing a landslide susceptibility map is very important. For this, GISbased frequency ratio(FR) and logistic regression(LR) models have been applied using landslide inventory and the nine landslide factors(i.e. lithology, land use, distance from river & fault, slope, aspect, elevation, curvature and annual rainfall). Database construction, weighting each factor classes or factors, preparing susceptibility map and validation were the major steps to be undertaken. Both models require a rasterized landslide inventory and landslide factor maps. The former was classified into training and validation landslides. Using FR model, weights for each factor classes were calculated and assigned so that all the weighted factor maps can be added to produce a landslide susceptibility map. In the case of LR model, the entire study area is firstly divided into landslide and non-landslide areas using the training landslides. Then, these areas are changed into landslide and non-landslide points so as to extract the FR maps of the nine landslide factors. Then a linear relationship is established between training landslides and landslide factors in SPSS. Based on this relationship, the final landslide susceptibility map is prepared using LR equation. The success-rate and prediction-rate of FR model were 74.8% and 73.5%, while in case of LR model these were 75.7% and 74.5% respectively. A close similarity in the prediction and validation rates showed that the model is acceptable. Accuracy of LR model is slightly better in predicting the landslide susceptibility of the area compared to FR model.Matebie METEN Netra Prakash BHANDARY Ryuichi YATABE 2015Journal of Mountain Science2015,12,6:6
