Three-Dimensional Reconstruction of Brain Surface Anatomy Based on Magnetic Resonance Imaging Diffusion-Weighted Imaging: A New Approach

Abstract

Fifty normal noninfarct patients and 12 cases with infarcts of the cerebrum were examined with routine magnetic resonance imaging and echo-planar diffusion-weighted imaging. The diffusion-weighted three-dimensional images were reconstructed with volume-rendering processing on workstation. Precentral gyrus, postcentral gyrus, superior parietal lobule, superior frontal gyrus, precentral sulcus, central sulcus, postcentral sulcus, intraparietal sulcus and superior frontal sulcus were best shown of all structures with an arbitrary score of 2.61–2.77. Supramarginal gyrus, middle frontal gyrus, inferior frontal gyrus and lateral sulcus were clearly shown in the majority of the cerebra with average scores of 2.0–2.49; angular gyrus, inferior frontal sulcus and superior temporal gyrus were not demonstrated satisfactorily and their average scores were 1.67–1.89. Middle temporal gyrus, inferior temporal gyrus, superior temporal sulcus and inferior temporal sulcus were difficult to identify, and thus had average scores of 0.87–1.26. Brain surface structures were better displayed in the older group of individuals than in the younger group. The structures in the 12 cases with acute or chronic cerebrum infarcts were also satisfactorily demonstrated with this new technique.

Correlation between ischemia-modified albumin and lipid levels in patients with acute cerebrovascular disease

“…Additionally, ACVD events result in high rates of disability due to lasting neurological damage (2). The key to reducing morbidity and mortality associated with these events is early diagnosis and treatment.…”

“…ACVD frequently affects older individuals, resulting in an increase in morbidity and mortality rates each year in China. However, changes to the living environment and diet structures are also key factors that should be considered (2). Notably, early diagnosis and treatment are able to reduce the degree of neurological impairment and mortality resulting from ACVD events (3).…”

“…ACVD diagnosis currently relies heavily on neuroimaging (2). However, studies conducted in China and worldwide have focused on the identification of biochemical markers to improve early diagnosis and to distinguish between ischemic and hemorrhagic stroke, similar to the way in which troponin is used to diagnose acute myocardial infarction (2).…”

“…However, studies conducted in China and worldwide have focused on the identification of biochemical markers to improve early diagnosis and to distinguish between ischemic and hemorrhagic stroke, similar to the way in which troponin is used to diagnose acute myocardial infarction (2). One biochemical marker, ischemia-modified albumin (IMA), has been widely studied in tissue ischemia in recent years.…”

“…Although non-invasive identifi cation of specifi c cerebral surface structures is crucial to clinical diagnosis and intervention, conventional MRI often fails to provide satisfactory outcome data due to the crude resolution of the tomographic slices [23]. Gong et al [23] reported a new technique using MR-traced diffusion-weighted imaging that displays clear structures of the cerebral surface in normal subjects.…”
