The objectives of this study were to evaluate the correlations of the volumes of the gray matter and white matter with age, and the correlations of the tissue probabilities of the gray matter and white matter with age and several cerebrovascular risk factors. We obtained magnetic resonance (MR) images of the brain and clinical information from 769 normal Japanese subjects. We processed the MR i...
Accurate and consistent multiple sclerosis (MS) brain lesion segmentation and volumetry could be an added value to MS clinicians. In this paper, MSmetrix is presented, an automatic and reliable method, which uses 3D T1-weighted and FLAIR MR images in a probabilistic model to detect white matter lesions as an outlier with respect to the normal brain, while segmenting the brain tissue into grey m...
BACKGROUND/AIMS Computed tomography (CT) hepatic volumetry is currently accepted as the most reliable method for preoperative estimation of graft weight in living donor liver transplantation (LDLT). However, several factors can cause inaccuracies in CT volumetry compared to real graft weight. The purpose of this study was to determine the frequency and degree of resection plane-dependent error ...
Abstract Background Multiple sclerosis is a chronic demyelinating disease of the central nervous system. It may lead to disability and cognitive impairment. Our study aimed at evaluation role MR volumetry technique in detection brain atrophic changes patients with multiple its impact on prognosis. Results This was carried out thirty healthy control mean age 26.23 years remitting relapsing scler...
Although there are many imaging studies on traditional ROI-based amygdala volumetry, there are very few studies on modeling amygdala shape variations. This paper presents a unified computational and statistical framework for modeling amygdala shape variations in a clinical population. The weighted spherical harmonic representation is used to parameterize, smooth out, and normalize amygdala surf...
