The aim of the study was to determine the possibilities of two differently acquired two-dimensional fast imaging with steady-state precession (FISP 2D) magnetic resonance sequences in estimation of the third ventricle floor fenestration patency after endoscopic third ventriculostomy (ETV) in the subjects with aqueductal stenosis/obstruction.Fifty eight subjects (37 males, 21 females, mean age 2...

OBJECTIVE This study aims to investigate the length and shape of the nasal bones in fetuses with trisomy 21 at 16-24 weeks' gestation. METHOD We acquired three-dimensional volumes of the fetal profile from 41 fetuses with trisomy 21. The multiplanar mode was used to measure nasal bone length in the exact midsagittal plane and in parasagittal and oblique views of the fetal face and to examine ...

OBJECTIVE The purpose of this study was to determine, when measuring prostate volume by TRUS, whether height is more accurately determined by transaxial or midsagittal scanning. MATERIALS AND METHODS Sixteen patients who between March 1995 and March 1998 underwent both preoperative TRUS and radical prostatectomy for prostate cancer were included in this study. Using prolate ellipse volume cal...

To correctly perceive visual directions relative to the head, one needs to compensate for the eye's orientation in the head. In this study we focus on compensation for the eye's torsion regarding objects that contain the line of sight and objects that do not pass through the fixation point. Subjects judged the location of flashed probe points relative to their binocular plane of regard, the mid...

Using high-resolution in-vivo magnetic resonance morphometry of the midsagittal area of the corpus callosum (CC) and four callosal subareas in 21 children with developmental language disorder (DLD) of the phonologic-syntactic type we found no significant anatomical differences in comparison to an age- and gender-matched normal control group. There was also no significant between-group differenc...

Conventional real-time magnetic resonance imaging (RTMRI) of the upper airway typically acquires information about the vocal tract from a single midsagittal scan plane. This provides insights into the dynamics of all articulators, but does not allow for visualization of several important features in vocal tract shaping, such as grooving/doming of the tongue, asymmetries in tongue shape, and lat...

This study examines the corpus callosum in 68 readers nested in 24 families. Callosa were measured and controlled for whole brain volume, intelligence, and gender. The relation of corpus callosum size to the within-family variance of oral reading was investigated with various measurements: volume, midsagittal area, and anterior-to-posterior one-fifth area segmentations. Because this is the firs...

The corpus callosum is the brain’s primary pathway for interhemispheric communication between the left and right hemispheres, and abnormal function and anatomy of the corpus callosum have been associated with a variety of disorders in humans and animals. In this study, we mapped quantitative trait loci (QTLs) modulating corpus callosum size in mice. By using mouse brain sections and stereologic...

Real-time magnetic resonance imaging (rtMRI) is a valuable emerging tool for studying the dynamics of vocal production. Conventional 2D rtMRI typically images the midsagittal plane of the vocal tract, acquiring data from all the important articulators. Dynamic 3D MRI would be a major advance, as it would provide 3D visualization of the vocal tract shaping dynamics, especially for the modeling o...
