what does UCSF Hippocampus at baseline represent? And what is the unit of this column? It's observed that the value ranges from 4000 to 7000
It represents to the total gray matter tissue in mm3 (cc).
How different is it from the Left hippocampus volume and Right hippocampus volume? Can I consider UCSF Hippocampus at baseline in place of the former one for analysis?
