Volumetric assessment of the sella turcica: a re-evaluation

Folia Morphologica, 2022
BACKGROUND: The sella turcica volume is widely measured by the Di Chiro-Nelson method. The purpose is to compare the fidelity of a proposed volumetry method vs. the Di Chiro-Nelson method, using computed tomography (CT) images.
