Eight signs to delineate the superior temporal gyrus, Heschl gyrus (HG), parahippocampal gyrus, rhinal sulcus, collateral sulcus proper, or the occipitotemporal sulcus, or a combination, were evaluated in the sagittal or axial plane. Two neuroradiologists independently evaluated each sign; the sign ...
MRI scans of head (n=236) were reviewed retrospectively to identify abnormalities of temporal lobe, third ventricle, and temporal horn of lateral ventricle. Patients were divided into 3 study groups according to their age. Using axial and coronal views of the cerebral hemispheres, interuncal ...
Purpose : To examine the frequency of hippocampal, cerebral, and cerebellar cortical atrophy in patients with intractable temporal lobe epilepsy (TLE) on reverse T,-weighted coronal images or on T,-weighted axial images. Methods : Eleven control subjects and 70 patients, who had been treated for...

Using three-dimensional extraction and visualization of the Rolandic sulcus after it was manually outlined on T1 weighted axial MRI slices, another group has established that this sulcus could be divided into three different regions that were linked with functional anatomy, since the middle segment, ...
