External Email - Use Caution I have used both CAT12 and Freesurfer to segment a particular brain scan and I get completely different volumes.
CAT12 (cc) Freesurfer 7.3.2 (cc) 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 volume (cc): 1618.09 1309 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.
