Timely, accurate and reliable assessment of fetal brain development is essential to reduce short long-term risks fetus mother. Fetal MRI increasingly used for assessment. Three key biometric linear measurements important evaluation are Cerebral Biparietal Diameter (CBD), Bone (BBD), Trans-Cerebellum (TCD), obtained manually by expert radiologists on reference slices, which time consuming prone ...

Purpose: Researchers have sought to better understand Chiari type I malformation (CMI) through morphometric measurements beyond tonsillar position (TP). Soft tissue and bone structures within the brain and craniocervical junction have been shown to be different for CMI patients compared to healthy controls. Yet, several morphological characteristics have not been consistently associated with CM...

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.

A model of speech motor control is presented, based on Feldman' s ( 1966) Equilibrium Point Hypothesis. An assessment of this model is proposed, including the control of a 2D biomechanical model of the tongue. Articulatory and acoustic patterns synthesized with this model for various vowel-to-vowel transitions, are compared to data collected on a French native speaker, with an electromagnetic m...

OBJECTIVES The purposes of this study were to construct reference limits for corpus callosum dimensions measured on images reconstructed from 3-dimensional (3D) sonography and to evaluate the reproducibility of these measurements. METHODS Three-dimensional sonographic volumes were acquired transabdominally from an axial view of the head in 361 fetuses cross-sectionally studied at 18 to 32 wee...

Without providing any support for their claim, Holloway and Broadfield (H&B) assert that ‘‘the Falk and Clarke (2007) reconstruction of Taung miscalculates the midsagittal plane, resulting in a significant reduction in cranial capacity that may call into question the taxonomic significance of the fossil’’ (Holloway and Broadfield, 2011:322). We agree that the 22 cm difference in the capacities ...

Despite the increasing recognition of the functional and clinical importance of lumbar lordosis, little is known about its description, particularly in Egypt. At the same time, magnetic resonance imaging (MRI) has been introduced as a noninvasive diagnostic technique. The aim of this study was to investigate the anatomy of the lumbar lordosis using midsagittal MRIs. Normal lumbar spine MRIs obt...

Corpus Callosum (CC) is an important white-matter structure in the human brain. Magnetic resonance imaging (MRI) is a non-invasive medical imaging technique that provides high resolution images for the structures. Segmentation is an important step in medical image analysis. This paper proposes a fully automated technique for segmentation of CC on the midsagittal slice of T1-weighted brain MR im...
