The current gold standard for hippocampus segmentation in MRI is manual delineation of the structure’s borders As a result, clear segmentation of this structure in MRI Regions in which neurogenesis occurs (Anand and DhikavĢ012). Used as one of the indicators (Csernansky et al. Schizophrenia, Alzheimer’s disease, epilepsy and among otherĬonditions the shape of hippocampus is altered and could be The abnormality of this structure is thought to be associated with neurodegenerativeĭiseases and brain disorders such as Alzheimer’s disease, mildĬognitive impairment, traumatic brain injury, schizophrenia,Įpilepsy and major depression (Geuze et al. Spatial navigation, learning, regulation of hypothalamic functions and emotional behaviour. It is involved in many functions such as memory, The most important subcortical brain structures is the hippocampus. This has many applications in diseaseĭiagnosis, therapy procedures and surgical planning. Images, such as in Magnetic Resonance Imaging (MRI), noninvasively provides information about the shape and volume of The morphological analysis of brain structures in medical Therefore, this method can be an optionįor accurate and robust segmentation of the hippocampus. Showed a high degree of accuracy (91% and 75%, respectively). Classiﬁcation results for AD vs control and MCI vs control Gold standard compared to those of Freesurfer.

Similarity indices, the results of our algorithm (mean Dice = 0.847) were more comparable with the

This method was applied to a set of 36 MRI scans provided by the Alzheimer’s Disease Neuroimaging The proposed method avoided the algorithms which requiredĪ large database and instead used a more complex level set approach to obtain comparable accuracy. Region-Based Active Contours) algorithms. With the SBGFRLS (Selective Binary and Gaussian Filtering Regularised Level Set) and LAC (Localising In this study, we used a novel level-set method for hippocampus segmentation in combination Manual segmentation of the hippocampus is highly time-consumingĪnd has low reproducibility however, automated methods have introduced substantial gains in this

Hippocampus segmentation in MR images is beneﬁcial for the diagnosis of many diseases and pathologies such as Alzheimer’s disease.
