Hippocampal Volumetry

Hippocampal Volumetry (HV) is a neuroimaging technique that makes it possible to reduce the interaction time and increase the reliability of hippocampus measurement

The hippocampus is a structure located in the temporal lobe of the brain. It belongs to the limbic system. The hippocampus plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation.


Atrophy of the medial temporal lobe (and especially, of the hippocampus and the entorhinal cortex) is a biomarker of mild cognitive impairment (MCI) and Alzheimer’s disease progression. The rate of atrophy varies from 3 to 6% per year in Alzheimer’s disease, whereas it is limited to 0.3–2.2% per year in normal aging (Frisoni et al., 2010). Although visual rating scales or the manual outlining of the hippocampus can be used, automated software programs, such as BrainMagix's SurferMagix module, reduce the interaction time and increase the reliability of the measurement. A harmonized protocol for hippocampal volumetry has been defined in order to reduce the variability between the studies (Frisoni and Jack, 2011).
