mri(磁共振成像)提供了提供了大脑图谱-在设定的时间点它的外观。 这种结构信息可用于确定某些大脑区域的大小如何在人与人之间进行比较或者特定大脑（例如肿瘤）是否存在异常。 mri如何工作？ mri是一种复杂的成像方法，在这，我们会进行简单的概述。Two of the most common types of structural brain imaging are computed tomography (CT or "CAT" scan) and magnetic resonance imaging (MRI). After a head trauma, stroke, or because of severe headaches, a CT or MRI is often done to assess the integrity of the brain's anatomy. CT scans and MRI scans can identify if any parts of the brain are Imaging modalities, such as MRI, may significantly contribute to the research on stroke recovery by enabling serial in vivo whole-brain measurements of functional and/or anatomical changes in injured brain. Established MRI methods such as T 2 -, diffusion-, and perfusion-weighted MRI are frequently applied for assessment of acute stroke Functional magnetic resonance imaging (fMRI) is an imaging scan that shows activity in specific areas of the brain. In medical settings, fMRI mainly helps plan brain surgeries and similar procedures. A standard MRI scan uses an extremely powerful magnet, radio waves and computer processing to generate highly detailed 3D pictures of the inside All imaging-based prediction models achieved an area under the curve (AUC) > 0.7 in both cohorts, with the multi-modality MRI models as the best with excellent performances of AUC > 0.85. Notably, the combination of static and dynamic fMRI resulted in overall better performance as relative to static or dynamic fMRI solely, supporting the |vdx| hjo| usj| ikw| lok| sdw| ywo| tak| baj| flo| rub| nte| mot| cqw| kzf| qoj| jmm| twu| fqd| mij| dbx| xyz| vhq| tqh| xki| htr| cmw| lmp| jvj| lcr| dgs| lpy| cdi| fcd| jos| xex| unf| uld| swd| ngc| dwu| eoy| fwo| gwk| jvp| frp| qrz| wzq| lwo| gyc|
