Flowchart of exclusion criteria. This study was conducted using stringent exclusion criteria. Of the 163 MRI examinations performed at the Coma Science Group between November 2009 and October 2013, 109 were excluded before image analysis. Data preprocessing was done for 54 patients, of which additionally 19 subjects had to be excluded due to inaccurate segmentation. Finally, we included 25 patients in the statistical analysis.
