Hemosiderin Detection inside the Mammillary Bodies Using Quantitative Susceptibility Mapping on Patients with Wernicke-Korsakoff Syndrome [PDF]
Hemorrhage inside the mammillary bodies (MMBs) is known to be one of the findings of Wernicke encephalopathy. Brain MRI of two patients with Wernicke-Korsakoff syndrome (WKS) demonstrated high susceptibility values representing hemosiderin deposition in ...

Fast quantitative susceptibility inversion based on dataweighting and split-Bregman algorithm [PDF]
定量磁化率成像(QuantitativeSusceptibilityMapping,QSM)是磁共振成像(MagneticResonanceImaging,MRI)中一项新兴的可用于研究组织特性和功能的技术。作为一种组织内在的物理特性,磁化率可以反映组织的铁含量、钙化、血氧饱和度等。因此,利用定量磁化率成像,可以有效地对这些信息进行定量分析。最近,定量磁化成像已经能够为脑出血、多发性硬化症、帕金森综合症、阿尔茨海默病等神经疾病的检测和研究提供帮助。 虽然有着广泛的应用前景 ...

The Role of MRI in Debunking the Fallacy of “Mild” Traumatic Brain Injury
ABSTRACT Mild traumatic brain injury (mTBI) is a prevalent yet often overlooked public health concern due to the absence of detectable abnormalities on CT or conventional MRI scans. Approximately 18.3%–31.3% of mTBI patients experience persistent symptoms 3–6 months post‐injury, despite normal imaging results, making diagnosis and treatment challenging.
