Abstract

Aim

We decided to study the relationship between brain volume and cranial capacity and the relationship between brain volume and age on a series of CT from healthy adults.

Methods

Fifty-eight healthy volunteers (27 women, 31 men, age range 18–95 years) were examined using our imaging protocols. The volunteers had no present or past neuropsychiatric illness and no abuse of alcohol or illicit drugs.

Results

Mean intracranial volume was 1,384.6 cm3 (standard deviation = 135.27, range 1,106–1,656) and mean brain volume was 1,201.0 cm3 (standard deviation = 142.52, range 791–1,500). Linear regression between brain volume and cranial capacity yielded this formula: brain volume = 182.3 + 0.7 × cranial capacity. Multivariate analysis yielded a relationship between cranial capacity, brain volume and age as follows: brain volume = 396.5–3.5 × age + 0.7 × cranial capacity.

Conclusion

This study could be supplemented by the collection of data such as, the size of the individuals in order to study the relationship between size of the brain and stature because this relation remains unclear.
