Change in brain volume and cortical thickness after behavioral and surgical weight loss intervention

NeuroImage: Clinical, 2019
Obesity is associated with reduced cortical thickness and brain volume, which may be related to poor nutrition. Given that brain atrophy in anorexia nervosa recovers with nutritional improvements and weight gain, it is worth examining how brain structure

Partial‐volume model for determining white matter and gray matter cerebral blood volume for analysis of gliomas [PDF]

Journal of Magnetic Resonance Imaging, 2006
AbstractPurposeTo model the partial voluming of gray matter (GM) and white matter (WM) in perfusion imaging, and to use this model to estimate the cerebral blood volume (CBV) of pure WM and GM, which could then be used to normalize data across patients in preparation for analyzing tumor perfusion.Materials and MethodsDynamic susceptibility contrast ...

Regional grey and white matter changes in heavy male smokers.

PLoS ONE, 2011
Cigarette smoking is highly prevalent in the general population but the effects of chronic smoking on brain structures are still unclear. Previous studies have found mixed results regarding regional grey matter abnormalities in smokers.

Impact of Decreased Visibility of Deep Medullary Veins on White Matter Integrity in Patients with Cerebral Small Vessel Disease

Journal of Integrative Neuroscience, 2023
Background: Based on susceptibility-weighted imaging (SWI) visibility, deep medullary vein (DMV) scores are related to white matter damage (WMD) in patients with cerebral small vessel disease (CSVD).

Automated White Matter Total Lesion Volume Segmentation in Diabetes [PDF]

American Journal of Neuroradiology, 2013
WM lesion segmentation is often performed with the use of subjective rating scales because manual methods are laborious and tedious; however, automated methods are now available. We compared the performance of total lesion volume grading computed by use of an automated WM lesion segmentation algorithm with that of subjective rating scales and expert ...
