This study investigated the texture features and volumes of bilateral hippocampus and medial temporal lobe (MTL) in magnetic resonance imaging (MRI) in patients with Alzheimer's disease (AD). Texture features were extracted using gray level co-occurrence matrix (GLCM) in 29 elderly AD patients, 19 age-matched non-demented controls (EC) and 18 young healthy controls (YC). The correlation between texture...
Ischemic penumbra (IP), the target of thrombolytic therapies, could be estimated by the mismatch region between magnetic resonance imaging (MRI) diffusion- and perfusion-defined abnormalities; however, the accuracy of this method has been challenged recently. In this study, we try to establish a method for calculating IP size based on computed tomography perfusion (CTP) and to observe the early evolution...
This study compares the voxel-based morphometry (VBM) and region-of-interest (ROI)-based volumetric analysis in schizophrenia. Magnetic resonance imaging (MRI) data of 50 unmedicated schizophrenia patients and 82 healthy controls were examined. ROI- based volumetric analysis was performed by tracing caudates on anterior commissure and posterior commissure (ACPC)-positioned MRI. The comparison of 20...
