Cochlear FLAIR Signal Changes in Hearing Preservation Vestibular Schwannoma SurgeryAcoustic neuromaFLAIRVestibular schwannomaObjective: Cochlear fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) signal intensity has been shown to be elevated in patients with vestibular schwannomas (VS...
By linking brain tissue composition to FLAIR signal changes, our model could help unravel the pathophysiological mechanisms of ARIA〦 and, therefore, provide a useful tool for testing other potential mechanisms underpinning brain MRI abnormalities.

神经影像:颞叶T2WI/FLAIR高信号病变的鉴别诊断 尽管许多脑部疾病可有颞叶病变,例如MRI上可见T2WI/FLAIR高信号,但仅局限于颞叶或以颞叶受累为主的疾病缺比较少。对病变分布模式和相关影像学表现的认识有助于缩小鉴别诊断的范围。 图1:单纯疱疹病毒性脑炎;A:FLA...

FLAIR MRI is preferred for WML analysis since the usually high T2 signal from CSF is suppressed (Soltanian-Zadeh and Peck, 2001), emphasizing the high white matter disease signal. This is due to the increased water content associated with ischemia and demyelination which can be more robustly ...
