For example, Rademacher et al. generated a variability map of the corticospinal tract in humans by registering the myelin-stained pyramidal tracts from the 10 postmortem brains to Talairach coordinates and found that the right pyramidal tract was centered more anteriorly than the left.
The aneurysm can be imperceptible during ventricular diastole, but become evident when the contraction of the left ventricle pushes the protrusion into the right outflow tract.
Under normal circumstances, the main pulmonary artery (MPA), the left pulmonary artery (LPA) and right pulmonary artery (RPA) could be visualized at the right outflow tract view.
One possible interpretation of these findings is that corpus callosum damage prevents reorganisation and use of the right hemisphere tract to compensate for the left-sided damage.
In addition, the C9ORF72 cases showed increased radial diffusivity in left frontal superior longitudinal fasciculus and posterior corpus callosum, and in the right corticospinal tract.
The score furthermore correlated negatively with mean diffusivity in the right corticospinal tract (co-localized with negative correlation with L1) (Fig. 2E).
Region of interest TBSS analysis revealed a positive correlation for verbal fluency for 'animals' and L1 in a small region in the right corticospinal tract (Fig. 2G).
Transthoracic echocardiography showed a complex and irregular mass adherent to the endocardial surface of the right outflow tract and smaller floating structures of the right atrium (RA) and right ventricle (RV).
The presence of cardiac shunts, such as a VSD, can be confirmed by transthoracic color Doppler and spectral Doppler echocardiography, and are best visualized in the parasternal long four-chamber view and short-axis view of the right outflow tract.
Because of the leftward proximal-to-distal course of the RVOT, the most rightward portion of the right outflow tract is the bundle of His region, and the most leftward portion is the supravalvar myocardium above the anterior leaflet of the pulmonary valve.
