Magnetic resonance imaging (MRI) is the modality of choice for Pott's spine and is more sensitive as well as specific than other modalities. MRI demonstrates involvement of all the components of the spine, including vertebral body, intervertebral disc, the posterior elements, epidural extension of...
Forum (2) Inhomogeneityis the degree of lack ofhomogeneity, for example the fractional deviation of the localmagnetic fieldfrom the average value of the field. Inhomogeneities of the staticmagnetic field, produced by the scanner as well as by objectsusceptibility, is unavoidable inMRI. The large ...
为了改善教学素质和修改瑕疵,部分图片经过Photoshop微调,没有后期添加任何结构(如在脑干图片上没有显示脑神经)。我们建议您浏览脑(图解)单元,查看更详细完整的图示。 剖析大脑解剖区域 以下展示几个结合切片图和3D图的纵断面: 大脑叶:额叶、顶叶、颞叶、枕叶、脑岛和边缘叶(请留意边缘叶属于功能性区域,由其他脑叶部...

As for single scans, our study considered 2 different regions at the lumbar spine and thigh to find a reference slice for men and women to estimate SM, SAT, and VAT. The volumes were compared with optimal slice areas for each tissue and sex. A strong association of L3 areas and all ...

evaluable features (readability) and the presence and patternof lesions in axial and peripheral joints. Furthermore, global WBMRI scores ofinflammation and structural damage were constructed, and WBMRI findings werecompared with cl...
MRI provides a unique non-invasive window into the brain, yet is limited to millimeter resolution, orders of magnitude coarser than cell dimensions. Here, we show that diffusion MRI is sensitive to the micrometer-scale variations in axon caliber or patho
MRI was performed using a 3 Tesla scanner (Discovery MR750; General Electric Systems, Milwaukee, Wisconsin, US) equipped with a high-performance gradient system (50 mT/m). Signal reception was achieved using a combined antero-posterior phased-array surface coil and a spine array coil. MRI sequ...
