SOCR Datasets - Neuroimaging study of Prefrontal Cortex Volume across Species and Tissue Types
Data Overview
Neuroimaging MRI data from asymptomatic subjects was acquired to develop a structural brain atlas (Shattuck, et al., 2008). The raw data was processed in two different ways to test a research hypothesis that super-resolution image enhancement would improve automated volume parcellation. Thus, an automated volume parcelation (Tu, et al., 2008) was applied first to the raw data and then to the super-resolved enhanced volumes (Marquina and Osher, 2007). Two measures of quality of the automated volume parsing were used -- sensitivity and specificity.
Finally the results of the Sensitivity and Specificity measures were compared for the two analysis protocols -- applying the auto-volume parser directly to the native data (Standard method) and preprocesisng the native data with super-resolution enhancement (Super-Resolved) before using hte automated volume parser. Of interest was whether the second protocol (supre-resolved analysis) would produce more reliable, consistent and accurate automated volume tesselations, compared to the first protocol (standard method) where a super-resolution preprocessing was not applied.
Data Description
- ICV – intracranial volume
- PFC – prefrontal cortex
- GM – gray matter
- Total – total volume
- WM – white matter
- SEM – standard error of the mean
