01
Your hippocampal volume, as a number
AI automatically extracts the left and right hippocampus and calculates the volume in cubic millimetres.
MRI screening of the hippocampus
BrainSuite is an examination
that measures the hippocampus in your brain.
From the head MRI images taken of you, AI automatically measures the volume of the hippocampus, the region that governs memory. You receive a clear report showing where you stand compared with the average for your age group. BrainSuite was developed under the supervision of the Institute of Development, Aging and Cancer, Tohoku University.

How you compare with your age group
Your result is plotted together with the average for the same sex and age group, so you can see where you stand on a graph.
03
Pointers for your daily habits
Depending on your result, the report suggests habits you can start today.
The sample images on this page are taken from the Japanese report and app.
From an actual analysis screen: the area in yellow is the hippocampus as identified by the AI.
Why the hippocampus
The hippocampus is the gateway to memory — it works when you learn something new — and it is also the brain’s control tower, putting what you learn to use together with other brain functions. It is a small region, less than one per cent of the whole brain, and it is one where atrophy with age can be seen.
It is also a place where the effects of how you live show up comparatively readily, not only the effects of age.
Because it begins to change little by little long before you notice any decline in memory, capturing the hippocampus as a number gives you one indicator for maintaining cognitive function.
- A region closely involved in how memories take hold
- Change in volume can be followed as a number
- Its relationship with daily habits is the subject of research
AI turns differences
too small for the eye into numbers.
AI analysis
BrainSuite automatically extracts the left and right hippocampus from the head MRI images taken of you and calculates the volume in cubic millimetres. Using an analytical model built from a large body of brain image data, it shows where you stand now, objectively, against the average for the same sex and age group.

The report
Report
CONTENTS
The report is made up of four parts.
01
Hippocampal volume score
The volume of each side and the total are shown as numbers.
02
Comparison with your age group
You can see at a glance where you sit within the distribution for the same sex and age group.
03
MRI images
The cross-sectional images actually taken, and the hippocampal region the AI identified.
04
Lifestyle advice
Suggestions for your next step, from four angles: exercise, sleep, diet and social connection.
The report shown here is the Japanese version. An English version exists, but whether it is offered is decided by each medical institution — please check with the institution before you book.

Frequently asked questions
Q. Is the examination safe?
A. MRI uses magnetism, so there is no exposure to radiation. No pain and no injection are involved. Please be aware, however, that the scanner is loud and that you will need to stay in an enclosed space for a period of time. People with metal in the body, such as a cardiac pacemaker, may not be able to have the examination.
Q. Is there any supervision or evidence behind it?
A. BrainSuite was developed under the supervision of the Institute of Development, Aging and Cancer, Tohoku University. The interpretation of results and the advice are designed on the basis of research findings on hippocampal volume and daily habits.
Q. Where can I find the Brain-ID and password to log in to MyBrain?
A. There are two places you can find it:
The result notification email
from the medical institution
The final page of
your result report
Q. How do I get to MyBrain?
A. Through the "MyBrain" button at the top right of the BrainSuite website, or the URL in your results notification email. It works on both computers and smartphones.
Q. How long does the examination take?
A. The MRI scan takes about 10 to 15 minutes. Including reception, you can expect to be on your way within about 30 minutes.
Q. Is there any radiation exposure or pain?
A. MRI uses magnetism, so there is no exposure to radiation. It involves no pain either.
Q. When will my report arrive?
A. It varies by institution, but as a guide it takes two to four weeks.
Q. Does a ticket expire?
A. Please have the examination within 12 months of purchase. You may change the institution within that period.
