A protocol for manual segmentation of medial temporal lobe subregions in 7 Tesla MRI
Recent advances in MRI and increasing knowledge on the characterization and anatomical variability of medial temporal lobe (MTL) anatomy have paved the way for more specific subdivisions of the MTL in humans. In addition, recent studies suggest that early changes in many neurodegenerative and neuropsychiatric diseases are better detected in smaller subregions of the MTL rather than with whole s...
متن کاملA comprehensive protocol for manual segmentation of the medial temporal lobe structures.
The present paper describes a comprehensive protocol for manual tracing of the set of brain regions comprising the medial temporal lobe (MTL): amygdala, hippocampus, and the associated parahippocampal regions (perirhinal, entorhinal, and parahippocampal proper). Unlike most other tracing protocols available, typically focusing on certain MTL areas (e.g., amygdala and/or hippocampus), the integr...
متن کاملEndoscopic Transsphenoidal Resection of a Medial Temporal Arachnoid Cyst in a Patient with Temporal Lobe Epilepsy
Abstract Introduction: Arachnoid cysts are developmental cystic lesions which may be found as an incidental finding on neuroimaging or present with symptoms of headache, seizure and neurologic deficit. Presentation with seizure is more common with larger sizes and temporal location. Presentation with TLE is rare, and fenestration of cysts had variable results for seizure control. Here in, we r...
متن کاملA reliable protocol for the manual segmentation of the human amygdala and its subregions using ultra-high resolution MRI
The measurement of the volume of the human amygdala in vivo has received increasing attention over the past decade, but existing methods face several challenges. First, due to the amorphous appearance of the amygdala and the difficulties in interpreting its boundaries, it is common for protocols to omit sizable sections of the rostral and dorsal regions of the amygdala comprising parts of the b...
متن کاملSegmentation Of Regions In The Medial Temporal Lobe
This thesis describes a method used to construct a segmentation algorithm for the Medial Temporal Lobe(MTL) in the human brain. The regions of interest in the MTL consists of four closely connected cortical areas, hippocampus and amygdala. A set consisting of 13 MRI scans of di erent individuals with matching manual expert annotations of the MTL were delivered, and the intensity images was stan...
