I have used both CAT12 and Freesurfer to segment a particular brain scan
and I get completely different volumes.
CAT12 Freesurfer 7.3.2
Left Cerebral WM(cc): 209 242
Left Cerebral Cortex (cc) 444 269
Left Lateral Ventricle (cc): 28 43
Right Cerebral WM (cc): 208 242
Right Cerebral Cortex (cc): 440 270
Right Lateral Ventricle (cc): 20 28
----------------------------------------------
Total 1350 1095
Total brain volume (cc): 1618 1309
Total Intercranial Volume N/A 1852
What could be causing this difference?
The brain scan was done with MPRAGE protocol with 176x256x256 voxels of
size 1mmx0.976mmx0.976mm
Which one is correct?
The scan is of a normal adult male aged 62 with chronic migraine.
Resent a second time because table did not work well in either of
previous attempts
