External Email - Use Caution 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 On Fri, Jun 9, 2023 at 9:00 AM Michael Mc Laughlin <mich...@thecurate.com> wrote: > 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. > > Resent because table did not work well > > Michael McLaughlin, > > On Fri, Jun 9, 2023 at 8:19 AM Michael Mc Laughlin <mich...@thecurate.com> > wrote: > >> 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 White Matter volume(cc): 209 Left hemisphere cerebral >> white matter volume 242 >> Left Cerebral Cortex volume(cc): 444 Left hemisphere cortical gray >> matter volume 269 >> Left Lateral Ventricle volume(cc): 28 Left-Lateral-Ventricle 43 >> Right Cerebral White Matter volume(cc): 208 Right hemisphere cerebral >> white matter volume 242 >> Right Cerebral Cortex volume(cc): 440 Right hemisphere cortical gray >> matter volume 270 >> Right Lateral Ventricle volume(cc): 20 Right-Lateral-Ventricle 28 >> Total 1350 Total 1095 >> Total volume (cc): 1618.09 Brain Segmentation Volume 1309 >> Estimated Total Intracranial Volume 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. >> >> Michael McLaughlin, >> >>
