We recently introduced a CSF MRI sequence to automatically measure intracranial volume (ICV) and brain parenchymal volume (BPV). This sequence with short imaging time (0:57 min) and fast post processing correlates well with qualitative brain atrophy scores. This study demonstrates that the low resolution and high resolution CSF MRI sequences perform well in the assessment of BPV and ICV, with a precision similar to the conventional brain segmentation methods FSL, Freesurfer and SPM. The CSF MRI sequence showed a good to very good correlation with the conventional segmentation methods for ICV and BPV.
