HV volume and Whole Brain Images

[sudv...@gmail.com]

There are some hippocampal volume mask images (segmented area of HV) in the postprocessed inventory of ADNI/LoNI dataset. 

How can I have access to the whole brain images before providing those masks? 

Thank you

All of the original images are available for download in the IDA (original scans). For ADNI-1, GO, 2, there are also pre-processed images, which have undergone various corrections by the MRI Core (Gradwarp, etc.). In ADNI-3, the corrections that had been done by the MRI Core during earlier phases of ADNI were done automatically by the scanners at the time of the acquisition. It also looks like there may be whole brain masks available (in the preprocessed section) according to the following information: ADNI |  Data Types (usc.edu) under MRI and Available Image Data.
