How Analyze was Used
“Analyze 11.0 (AnalyzeDirect, KS, USA) was used to calculate the total volumes of the superior sagittal and transverse venous sinuses using the 3D PC-MRV data acquired at each time point. The semi-automatic threshold technique (using standardized minimum and maximum threshold values) was used to define and extract the appropriate venous sinuses to enable automated volume calculation.
The deep venous space was calculated in by quantifying the total volume of all voxels corresponding with deep veins within the brain tissue, which have low signal intensity on SWI.”
