Performing VAI analysis in batch mode

VAI analysis can also be performed in batch module, like standard perfusion analysis.
Start the Batch module from the <Modules> main menu list.
Go to the <Perfusion analysis> tab and then the <VAI> sub-tab:

Like the analysis of standard perfusion data, data can be either in Dicom or Nifti format. For Dicom images, the VAI series must be present as a single 5D series containing both the GRE and the SE series in one directory. It is assumed that the GRE part of the data has lower instance numbers than the SE series so that the GRE data appears before the SE data upon sorting. For Nifti input, the data can either be loaded as a single Nifti file containing both GRE and SE seires, or as two separate files; one for the GRE and one for the SE series. In the latter case, both files must be present in the same directory and the same directory as specified in the <perfusion subdir> specified under the <Main> tab.

An ADC map can also be specified (needed for vessel size index calculation). The ADC map must be in Nifti format and stored in the same folder as the perfusion data. If no ADC map is specified, a default constant ADC value (as specified) will be used.
