Dehydration confounds the assessment of brain atrophy.

چکیده
Computerized brain volumetry has potential value for diagnosis and the follow-up evaluation of degenerative disorders. A potential pitfall of this method is the extent of physiologic variations in brain volume. The authors show that dehydration and rehydration can significantly change brain volume: lack of fluid intake for 16 hours decreased brain volume by 0.55% (SD, +/-0.69), and after rehydration total cerebral volume increased by 0.72% (SD, +/-0.21).

Plastination and Staining of Brain Slices Using Two Different Dehydration Methods
Introduction: Unstained formalin-fixed whole brain specimens and brain slices do not give satisfactory results for teaching neuroanatomy. In addition, difficulties in obtaining human brains for dissection have increased the demand for more durable brain specimens that have been obtained by the plastination technique. In the present study brain specimens were sliced, fixed and stained using...
متن کاملHippocampal Atrophy Studying in Alzheimer's Disease Diagnosis Using Brain MRI Images
Background and Aim: For effective treatment of Alzheimer's disease (AD), it is important to accurately diagnosis of AD and its earlier stage, Mild Cognitive Impairment (MCI). One of the most important approaches of early detection of AD is to measure atrophy, which uses various kinds of brain scans, such as MRI. The main objective of the current research was to provide a computerized diagnostic...

The purpose of this study was assessment of brain atrophy and cognitive dysfunction during the first two years of disease evolution. Patients and Methods: In a case-control study, 50 cases as patients and 50 normal ones as the control group were included. Twelve patients were male (24%) a...
متن کاملCorrelation between brain volume change and T2 relaxation time induced by dehydration and rehydration: Implications for monitoring atrophy in clinical studies
Brain volume change measured from magnetic resonance imaging (MRI) provides a widely used and useful in vivo measure of irreversible tissue loss. These measurements, however, can be influenced by reversible factors such as shifts in brain water content. Given the strong effect of water on T2 relaxation, we investigated whether an estimate of T2 relaxation time would correlate with brain volume ...
متن کاملAn Improved MRI Segmentation for Atrophy Assessment
An efficient brain segmentation technique of magnetic resonance image (MRI) is proposed for the sake of atrophy detection. Early detection of brain atrophy indicates many neurodiseases. The paper also proposes a new simple assessment for brain atrophy as an atrophy ratio measure. Experiments on cognitive normal and atrophied MRI Brain images demonstrate the promising segmentation results of the...
