Magnetic resonance imaging (MRI) is a non-invasive neuroimaging
technique that is useful for identifying normal developmental and aging processes
and for data sharing. Marmosets have a relatively shorter life expectancy than other
primates, including humans, because they grow and age faster. Therefore, the common
marmoset model is effective in aging research. The current study investigated the
aging process of the marmoset brain and provided an open MRI database of marmosets
across a wide age range. The Brain/MINDS Marmoset Brain MRI Dataset contains brain
MRI information from 216 marmosets ranging in age from 1 and 10 years. At the time
of its release, it is the largest public dataset in the world. It also includes
multi-contrast MRI images. In addition, 91 of 216 animals have corresponding
high-resolutionex vivoMRI datasets. Our MRI
database, available at the Brain/MINDS Data Portal, might help to understand the
effects of various factors, such as age, sex, body size, and fixation, on the brain.
It can also contribute to and accelerate brain science studies worldwide.
