A morphological study of the shape of the corpus callosum in normal, schizophrenic and bipolar patients.

Abnormalities in the morphology of the corpus callosum have been found to be involved in cognitive impairments or abnormal behaviour in patients with mental disorders such as schizophrenia and bipolar disorder. The present study investigated morphological shape differences of the corpus callosum in a large cohort of 223 participants between normal, schizophrenic and bipolar patients on MRI scans, CT scans and cadaver samples. Healthy samples were compared to a mental disorder population sample to determine morphological shapes variations associated with schizophrenia and bipolar disorder.

Morphology of the internal auditory canal: Deriving parameters from computer tomography scans. An observational STROBE-MR study.

Objectives: The objective of this study is to identify and define landmarks to adequately describe the internal auditory canal for inclusion in three-dimensional computational models of the cochlea and its surrounding structures.

Participants: Computer tomography scans of live human cochleae were collected in the retrospective period. Descriptive and comparative statistics were used to describe the data obtained from the scans.

The midline mandibular lingual canal: importance in implant surgery.

Purpose: The study aims to determine if midline mandibular dental implants pose a risk for the midline lingual canal (MLC).

Materials And Methods: Cone beam computed tomography was used to scan 122 mandibles (31 black males; 28 black females; 32 white males and 31 white females). Midsagittal sections in the reconstructed images were made.
