Cortical thickness (Cth) provides crucial information about normal brain development. Measured Cth could depend on multiple factors such as gender, field strength and type of MRI scanner. The dependence of Cth on field strength has not been studied in a large sample size. Also, with the increased use of 3T scanners, evaluating the effect of higher field strength on Cth is critical. This study evaluates the effect that gender and field strength has on measured cortical thickness and its age-dependent changes in a large cohort of 300 healthy controls.
