Diffusion Data

1.5T

So far, we recruited and shared with Core 1: 40 chronic schizophrenics and 40 controls scanned with the old DTI LSDI protocol (1.7x1.7x5 mm, 6 directions, 1 baseline ).

3.0T

We started acquiring images on the 3T GE scanner. So far, we recruited and scanned 14 schizophrenics and 12 normal controls with SENSE EPI protocol (1.7x1.7x1.7 mm, 51 directions, 8 baselines). All these subjects have also 1x1x1 structural scans available. We will either make the complete set of 26 cases available or the 12 normal controls.


The following scanner settings were used

000001.SER Volume- 3D localizer

000002.SER ASSET- parallel calibration scan

000003.SER DTI Volume - R= 17000, TE Min= 78.3, FOV= 24.0, #Slices= 81, Resolution= 144x144, NEX= 1, directions 51, + 8 x T2, 1.7 mm X 1.7 mm X 1.7 mm

000004.SER 3D FSPGR Axial, EDR, Fast, IvR, Asset - R= 7.5, TE= 3.0, FA=15 degrees, FOV= 25.6, 1 Phase FOV, Bandwith=15.63, Resolution= 256x256, Slice thickness 1

000005.SER FSE T2 Axial - R= 6200, TE= 103, FOV= 25.6, 0.75 Phase FOV, ETL=16, Bandwith=31.25, Resolution= 256x256, Slice thickness 2mm, interleaved

Labelmaps

Female caudate nucleus

We have new manually segmented labelmaps for the caudate nucleus of 32 women with schizotypal personality disorder and 29 normal control women. The caudate nucleus was delineated on coronal axis SPGR images (0.9375x0.9375x1.5 mm, 1.5T).

See Min-Seong et al. for details.

Previously available datasets

For previously available datasets see DataRepository.


Dartmouth

1.5T GE

fMRI

This is an EPI sequence acquired sagittally (3.75x3.75x5 mm)

Verbal Episodic Encoding/Recognition Task (event-related) - We have 14 subjects with schizophrenia and 9 normal controls.

Auditory-verbal n-back Working Memory Task - We have 20 subjects with schizophrenia and 20 normal controls.

DTI

This is an EPI sequence acquired axially (1.875x1.875x3 mm reconstructed to 0.9375x0.9375x3mm).

Pre-processed and reviewed - We have 17 subjects with schizophrenia and 11 normal controls.

Awaiting pre-processing and review - 15 subjects.

Potentially 43 subjects total.

Structural

All subjects have a hires SPGR 3D Volume (0.9375x0.9375x1.5 mm)

3.0T Philips

Acquisition has now started. Trial case with DTI, fMRI Motor, and MPRAGE structural was incorporated in NAMIC tutorial.

Previously available data

For previously available datasets see DataRepository.
