3D quantitative synthetic MRI-derived cortical thickness and subcortical brain volumes: Scan-rescan repeatability and comparison with conventional T -weighted images.

Background: Previous quantitative synthetic MRI of the brain has been solely performed in 2D.

Purpose: To evaluate the feasibility of the recently developed sequence 3D-QALAS for brain cortical thickness and volumetric analysis.

Study Type: Reproducibility/repeatability study.
