Hi everyone!

I am new on MRIcrogl analysis and I need some help :)
Here is my aim: to measure the volume of flair white matter hyperintensity.
It has been mentioned in literatures that there are four steps:
1. Use semi-automatic technology of MRIcro to select all high-signal areas as ROI 1；
2.Manually select white matter high-signal area as ROI 2；
3.The overlap of the two ROIs is the final ROI of white matter high signal；
4.Measure the corresponding volume through the final ROI.
Do you have any recommandations for conducting steps 1, 3 and 4?

Thanks a lot!!

You may want to see if one of the many automated tools can help (e.g. FSL's BIANCA). You may want to look at the MRIcroGL manual. In particular, the "Intensity Filter" seen in the Draw/Advanced menu. The "Mouse gestures" item of the "Help" menu will tell you the key shortcuts for your operating system.
