T2 signal abnormality was seen more commonly in scans obtained 3 or more days after surgery than in those collected immediately postoperatively. No differences in age, anatomical target, diagnosis, or number of microelectrode passes were noted between patients with or without T2 signal. Further ...
病灶周围非增强区域(non-enhancing peritumoral signal abnormality,NEPSA)通常呈现MRI-T2和FLAIR序列高信号,T1序列低信号,可有助病变的鉴别诊断。NEPSA病理特征以瘤周肿瘤细胞浸润为主,也可能是血管源性水肿、微梗死灶、炎症或胶质增生。传统MRI序列难以区分肿瘤浸润和血管源性水肿。新的MRI序列,如弥散加权成像(diffusio...
Figure 1 and Figure 2: Axial FLAIR and T2 weighted images show bilateral confluent deep periatrial white matter and splenium (red arrow in Figure 3) signal abnormality. There is notable sparing of the subcortical u-fibers (blue arrows), ...
一些数据表明,仅限于舌尖咬伤是晕厥的特异性损伤;然而,在ES和PNES中也观察到这种损伤模式。在脑磁共振成像中,我们观察到舌信号异常(tongue signal abnormality,TSA),这一异常随后被证明与舌咬伤相关,是支持未被识别的痫性发作诊断的征象。神经影像学常用于TLoC的评...

一些数据表明,仅限于舌尖咬伤是晕厥的特异性损伤;然而,在ES和PNES中也观察到这种损伤模式。在脑磁共振成像中,我们观察到舌信号异常(tongue signal abnormality,TSA),这一异常随后被证明与舌咬伤相关,是支持未被识别的痫性发作诊断的征象。神经影像学常用于TLoC的评估,发现TSA可能暗示ES是其潜在病因。
一些统计数据表明,之外背尖咬伤是晕厥的特异特质损害;然而,在ES和PNES中所也推论到这种损害模式。在脑磁共振成像中所,我们推论到背接收器反常(tongue signal abnormality,TSA),这一反常随后被表明与背咬伤特别,是支持未被识别的痫特质癫痫病人的征象。骨骼肌底片学常用于TLoC的指标,发现TSA似乎暗示ES是其潜在成因。
在脊髓造影高分辨率中的,我们观察到鼻频谱精神状态(tongue signal abnormality,TSA),这一精神状态随后被证明与鼻咬人特别,是支持未能被识别的痫性猝死病症的哮喘。神经MRI类似于于TLoC的审核,断定TSA也许暗示ES是其潜在疾病。 2021年9月来自宾夕法尼亚州的Paul M. Bunch等在 AJNR 上公布了他们的深入研究结果,他们...
在脑医学影像显微当中,我们判读到咽讯号所致(tongue signal abnormality,TSA),这一所致随后被证明与咽惊吓相关,是全力支持并未被识别的痫性猝死病患的病征。大脑影像学常用于TLoC的指标,挖掘出TSA可能会其实ES是其潜在病征。 2021年9月末来自英美两国的Paul M. Bunch等在 AJNR 上公布了他们的科学研究结果,他们假设...
Figure 1 and Figure 2: Axial FLAIR and T2 weighted images show bilateral confluent deep periatrial white matter and splenium (red arrow in Figure 3) signal abnormality. There is notable sparing of the subcortical u-fibers (blue arrows), better seen on the T2 weighted images where there is ...
