Variability of corpus callosal area measurements from midsagittal MR images: effect of subject placement within the scanner.
نویسندگان
چکیده
Variation in corpus callosum area measured from midsagittal MR images was evaluated in 12 healthy subjects who were each imaged four to seven times. Statistically significant differences between measurements of the same subject were found on 47% of the images, with an average difference of 5.9% between images.

Sexual Dimorphism and Age-Related Variations of Corpus Callosum Using Magnetic Resonance Imaging
Introduction: Despite technological advances and numerous published investigations, sexual dimorphism of Corpus Callosum (CC) remains a matter of ongoing controversy. In the present study on neurologically healthy Iranian adults, we investigated the possible gender- and age-related variations in anthropometric callosal measurements. Methods: Our sample comprised 35 male and 35 female sub...

PURPOSE To analyze changes of the human corpus callosum and MR midsagittal brain structures during normal aging. METHODS A morphometric evaluation strategy for quantification of these brain structures on MR scans was developed. This computerized measuring program did allow the acquisition of more than 100 one- and two-dimensional parameters. RESULTS During normal aging, the anterior parts o...
متن کاملBrain size: a possible source of interindividual variability in corpus callosum morphology
The corpus callosum (CC) is the main fiber tract connecting the cerebral hemispheres, and it has been estimated that about 200-350 million fibers run through this structure in the human brain (1,2). The CC seems to be important in the transfer and facilitation of associative information between the hemispheres. It is thought that the cross-sectional size of the CC may indicate the number of fib...
متن کاملFunctional significance of individual variations in callosal area.
We considered the hypothesis that the richness of callosal interhemispheric connections has a role in determining the degree of behavioural laterality and time-sharing ability in dual-task performance. Behavioural laterality as measured by dichotic word listening, line bisection and turning bias tests correlated inversely with the midsagittal cross-sectional area of the corpus callosum, as seen...
متن کاملMorphometrical Evaluation of Corpus Callosum Using Mid-Sagittal Brain MRI Images in Patients With Relapsing-Remitting Multiple Sclerosis Referred to Besat Hospital in Hamadan from April 2011 To April 2021; A Retrospective Study
Introduction: Corpus callosum (CC) as an intracranial organ is located in midline of cerebrum communicating both right and left hemispheres. CC undergoes morphological changes in multiple sclerosis (MS). Since the morphometrical changes of organs are directly associated with geographical regions, thus the aim of this study was to investigate the morphological alteration of CC in patients with r...
