Fig. 2From: Delineation of two intracranial areas and the perpendicular intracranial width is sufficient for intracranial volume estimationIntracranial volume estimation using method 3 in coronal orientation. The grey surface encloses the intracranial volume (ICV) to be estimated. The black line shows the coronal intracranial width, and the grey areas are two delineated coronal intracranial areas (ICAs). To calculate the ICV estimate using method 3, the coronal intracranial width is multiplied by the sum of the two ICAsBack to article page
