选取同期100名健康志愿者为对照组,所有研究对象均行颞下颌关节MRI常规序列平扫及T2 mapping成像,比较各组关节盘和盘后组织感兴趣区的T2值,采用单因素分析评价TMD患者关节盘移位不伴复位的影响因素,采用Logistic回归分析
MRI是磁共振成像，原理是施加一个磁场，让原子核和着磁场的节拍动起来（共振），当磁场停下来的时候，...
因为我不是学医的，只是病患家属，所以我不能保证内容正确：MRI interpretation
the role of myoglobin as an oxygen storage protein in the muscles of diving birds and mammals is well-established ([8][1]). In contrast, the function of the lower myoglobin content in striated muscles of humans and other terrestrial vertebrates has long been a subject of debate. In ...

但是,临床中不少患者nCRT前后的影像学检查缺乏同一性、图像数据不够充分,如评估方法不一致、并非nCRT前后均进行标准的盆腔磁共振高分辨扫描、缺少最关键的高分辨T2加权图像(high-resolution T2-weighted MR images,HR-T2WI),甚至缺失可供对...
本研究通过测量比较矢状位腰椎间盘T2加权（T2- Weighted images，T2WI）信号值与T2*值，试图量化分析椎间盘早期退变的生化改变，探讨应用T2* mapping技术在腰椎间盘早期退变MR成像诊断中的可行性。1 方法 1.1 临床资料 随机选取2014年8月-2015年1月来我科行腰椎间盘MRI检查患者40 名，其中男19名，女21名，...
In this work, we propose a fusion algorithm using CDF9/7 wavelet based on lifting scheme with specified fusion rules to combine pairs of multispectral Magnetic Resonance Imaging (MRI) such as T1, T2. The experimental results of brain tumor show that the proposed algorithm preserves both edge ...
T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), diffusion weighted imaging (DWI) and dynamic contrast enhancement (DCE) techniques have become routine sequences during the daily MRI scanning at present. The signal intensity on the weighted images cannot directly reflect the characteristics ...
A new type of dual-mode T1 and T2 magnetic resonance imaging (MRI) contrast agent based on mixed lanthanide oxide nanoparticles was synthesized. Gd3+ (8S7/2) plays an important role in T1 MRI contrast agents because of its large electron spin magnetic moment resulting from its seven unpaired...
