AIM: To describe MRI features, including diffusion-weighted imaging (DWI), magnetic resonance spectroscopy (MRS), and perfusion-weighted imaging (PWI), of intra-axial tumour-like presentations of four different subtypes of histiocytosis.Luna, L. P....
16-19 Studies in AN found elevated prediction error response to taste and monetary stimuli compared with healthy controls but a lower response in small studies in individuals with BN and individuals with overweight.20-23 Those studies suggested that the prediction error signal is inversely correlated...
A higher MS conversion rate was found in patients with a younger TDL onset age. 展开 关键词: Humans Brain Neoplasms Multiple Sclerosis Brain Edema Spinal Cord Diseases Demyelinating Diseases Disease Progression Diagnosis, Differential Magnetic Resonance Imaging Biopsy ...
left ventricular mass, echocardiography, MRI, brain morphology, cognitive functionLeft ventricular mass (LVM) has been shown to to serve as measure of target organ damage resulting from chronic exposure to several risk factors. Data on the association of mid-life LVM with later cognitive performance...
It revealed a strong negative correlation between blood 5-HT concentration and body mass and a strong negative correlation between the brain mass/body mass ratio and gut length. Also, a negative correlation was found between the volume of the hippocampal complex and blood tryptophan concentration. ...
Early consideration of cryptococcal is important as MRI findings of cryptococcoma are commonly misdiagnosed as brain tumours. Findings of multiple enlarged perivascular spaces involving bilateral basal ganglia should also prompt strong suspicion of gelatinous pseudocysts found in cryptococcal meningo...
1a). Detailed experimental parameters for MSI and SCMS can be found in Methods. Fig. 1: The MEISTER framework for multiscale biochemical profiling using high-mass-resolution MS enhanced by computational methods. a, Obtained from surgically extracted brain, serial tissue sections are imaged for 3D ...
The artificial intelligence (AI) methods used for interpreting MS data are emerging. Disease relevant biomarkers have been found using algorithms such as least absolute shrinkage and selection operator (LASSO), hierarchical cluster analysis (HCA), self-organizing map (SOM), random forest (RF), and...
9-12 Less is known about the effects of obesity and being overweight on brain development and how this might interact with cognitive ability. Many neuroimaging studies13-16 have found structural alterations in cortical regions involved in executive control in obese children compared with lean children...
A 50 year-old woman in the breast cancer group. A painful mass was found in the right breast for 2 weeks. Pathology: invasive ductal carcinoma. T1-weighted contrast-enhanced MRI (108 s) reveals a rim-enhanced mass with a thin wall, an irregular shape and a sp...
