Normalization of Cerebral Volumes by Use of Intracranial Volume ...
Measuring total intracranial volume (TIV) allows whole-brain and regional volumetric measures to be normalized for head size. The TIV can be defined as the volume within the cranium, including the brain, meninges, and CSF. We hypothesized that it also could be used to control for variations in voxel size over time.
Accurate Estimation of Total Intracranial Volume in MRI using a …
Total intracranial volume (TIV) is the volume enclosed inside the cranium, inclusive of the meninges and the brain. TIV is extensively used to correct variations in inter-subject head size for the evaluation of neurodegenerative diseases.

Note that the '711-2C' target image includes skull (the lack of '_with_skull' in the filename talairach.xfm is a bit misleading). To determine the scaling factor, 22 subjects for which the TIV has been determined manually via their T2-weighted scans …
Accurate automatic estimation of total intracranial volume: A …
Total intracranial volume (TIV/ICV) is an important covariate for volumetric analyses of the brain and brain regions, especially in the study of neurodegenerative diseases, where it can provide a proxy of maximum pre-morbid brain volume.

Total intracranial volume (TIV/ICV) is an important covariate for volumetric analyses of the brain and brain regions. It is commonly used to correct for head size variation (i.e., 'normalize' hippocampal volume size).
A Method to Estimate Brain Volume from Head CT Images and …
We present an automated head CT segmentation method (CTseg) to estimate total brain volume and total intracranial volume. CTseg adapts a widely used brain MR imaging segmentation method from the Statistical Parametric Mapping toolbox using a …

A skull-stripped version of the input image is produced by default (prefixed ss_ to the original filename). Total brain volume (TBV) and intercranial volume (TIV) are also computed by the algorithm and returned as the second argument of the CTseg function.
Accurate estimation of total intracranial volume in MRI using a …
Feb 15, 2021 · Total intracranial volume (TIV) is the volume enclosed inside the cranium, inclusive of the meninges and the brain. TIV is extensively used to correct variations in inter-subject head size for the evaluation of neurodegen- erative diseases.
Regional cortical and subcortical grey matter (GM) and white matter (WM) volumes correlate with total brain volume, which in turn is correlated with total intracranial volume (TIV).
Reliability and Utility of Manual and Automated Estimates of Total ...
This number represents the estimated total intracranial volume (eTIV), and is the extent of contraction or expansion required for the image to match the template. This estimation includes all CSF within the skull, including subarachnoid CSF.
