Web-based automated PET and MR quantification

P1⁄40.00153). According to the cognitive impairment level, a moderate positive correlation was observed in the MCI level (FAST stage: 2-3) (r1⁄40.310, t1⁄42.62, P1⁄40.0109), but no correlation was noted in the dementia level ( FAST stage 4) (r1⁄4-0.0771, t1⁄4-0.604, P1⁄40.548). Conclusions: Since the results of this study indicated that the Z score tends to increase with the FAST stage, the degree of atrophy of the medial temporal region is considered to increase with the severity of Alzheimer’s disease. While the Z score increased with the FAST stage in the MCI group, no correlation was observed between the FAST stage and Z score in the Alzheimer’s disease group. Therefore, the VSRAD was suggested to be useful as an index for the follow-up of patients with MCI.
