Background : The Alzheimer is a common progressive and degenerative disease which causes dementia and ruin of brain cells especially in Hippocampus region. Recently, it has been appeared that Erythropoietin with its neural-protective action causes an improvement in cognitive functions during this disease. This study aims to find an alternative approach instead of traditional intraventricular in...
The premature infant brain has been thoroughly studied by sonography, and normal standards for ventricular size have been established. Whether these apply to normal full-term infants is uncertain. Fifty-three healthy full-term infants were electively examined by real-time sonography through the anterior fontanelle on the first to sixth days of life. Nine had asymmetric lateral ventricles; two o...
In this study, a computational mapping technique was used to examine the three-dimensional profile of the lateral ventricles in autism. T1-weighted three-dimensional magnetic resonance images of the brain were acquired from 20 males with autism (age: 10.1+/-3.5 years) and 22 male control subjects (age: 10.7+/-2.5 years). The lateral ventricles were delineated manually and ventricular volumes we...
To compare the linear dimensions (width) of the foetal atrium and occipital horns to their areas, 31 foetuses (15-24 weeks, C-R 12.5-23.5 mm) from spontaneous abortions were evaluated. Images of the axial sections of the brains were transferred to computer and Scion for Windows 98 software was used for image analysis. 11 brains appeared normal and 20 were abnormal (leukomalacia in 9 cases, peri...
Brain tumor detection is still a challenge in the field of brain compute-aided diagnosis. In the brain Magnetic Resonance Images (MRI), the correlation between lateral ventricles deformations and tumor existence has been found useful in brain tumor detection and prediction. To retrieve the lateral ventricles deformation data for further statistical analysis and processing, a new method has been...
Symptomatic intraventricular developmental cysts of neuroepithelial origin occurring in the lateral and fourth ventricles are extremely rare. We report the clinical, radiologic, and computed tomographic (CT) findings in three such cases, two occurring in the lateral ventricles and one in the fourth ventricle, Within the lateral ventricles, these cysts are distinguished from colloid cysts by the...
BACKGROUND Enlargement of the lateral ventricles is thought to originate from abnormal prenatal brain development and is associated with neurodevelopmental disorders. Fetal isolated mild ventriculomegaly (MVM) is associated with the enlargement of lateral ventricle volumes in the neonatal period and developmental delays in early childhood. However, little is known about postnatal brain developm...
