Hippocampal Subfields
ASHS (external) is a tool for segmenting and labeling the hippocampal subfields and medial temporal lobe (MTL). The software uses T1 and T2 weighted MRI’s to segment the MTL and hippocampal subfields.
Purpose: The entorhinal cortex, CA1, and CA4/dentate gyrus subfields of the hippocampus have been linked to aging and AD pathology and have also been shown to be important for spatial memory (Yushkevich PA., et al., 2014).
Purpose: Studies have shown that whole brain volumes decrease approximately .45% per year in older adults (Fotenos Anthony F., et al., 2005).
Purpose: The cerebral aqueduct (CA) and C2-C3 region have been shown to be sensitive to the pathological changes that occur in aging and Alzheimer’s disease (El Sankari S., et al., 2011).
Purpose: Perivascular space size is associated with Alzheimer’s disease (Banerjee G., et al., 2017)
