Abnormal findings on brain MRI were categorized into four patterns: (1) hyperintense lesion in the pons on T2-weighted imaging (T2WI), (2) nonspecific white matter lesions, (3) infarct-like lesions, and (4) meningeal thickening and/or enhancement. Abnormal cerebral findings were detected in ...
This chapter discusses multifractal texture estimation and characterization of brain lesions (necrosis, edema, enhanced tumor, nonenhanced tumor, etc.) in magnetic resonance (MR) images. This work formulates the complex texture of tumor in MR images using a stochastic model known as multifractional ...
Segmentation based on information fusion applied to brain tissue on MRI An information fusion based fuzzy segmentation method applied to Magnetic Resonance Images (MRI) is proposed in this paper. It can automatically extract th... W Dou,S Ruan,D Bloyet,... - Proceedings of SPIE - The Interna...
Brain MR in patients with Langerhans cell histiocytosis: Findings and enhancement with Gd-DTPA The brains of eight patient with Langerhans Cell Histiocytosis (LCH) were studied with magnetic Resonance Imaging (MRI). One scan was normal and a spectrum......

Specifically, we found that the mean distance of the FCs was not significantly correlated with enhancement in the FCs in ASD (that is, correlation between the distance of an FC and its rASD À rTD; difference in correlations of FCs for ASD and TD, r ¼ 0.42, P ¼ 0.10) or with...
2. Result: the accuracy of localizing diagnosis was 100%, five neurogenic tumor showed longer t1 and longer t2 signals with abnormal contrast enhancement. three meningiomas showed iso-or longer t1 and iso-or longer t2 with signal of meningiomas can be inhomogeneous because it has calcification. ...
Functional expression of the R672S channels in human embryonic kidney 293 cells revealed a small but significant hyperpolarizing shift in the steady-state fast inactivation, and a dramatic enhancement in channel slow inactivation. These two defects are mainly due to a slow recovery of the mutant ...

根据第二段The brain science behind Alzheimer's is complex,but CT and MRI scans suggest that poisonous changes occur in the brain,including the abnormal buildup of proteins called amyloid plaques and tau tangles.(阿尔茨海默氏症背后的脑科学是复杂的,但CT和MRI扫描表明,大脑中发...
