Volumetry in AD, OD, and ND
| Volumetry left MTL/ICV | Volumetry right MTL/ICV | |
| AD (n=41) | 0.0037 (0.00053) | 0.0038 (0.00047) |
| OD (n=32) | 0.0038 (0.00060) | 0.0038 (0.00045) |

Values are means (SD). AD=Alzheimer's disease; OD=other dementias (see text); ND=non-demented subjects. MTL=medial temporal lobe (see text); ICV=intracranial volume; χ2: ADv ND p<0.0001 (left and right); ADv OD p>0.05 (left and right); ODv ND p<0.0001 (left and right). Four scans could not be measured for technical reasons.
