The software works great! It's user friendly and intuitive to use! I didn't like that you can only run one analysis at a time. This would be nice if you could do multiple analyses in succession (i.e. 2 different scans). Not much but it was something i noticed while using this product. I recommend going through all features before purchasing. You will learn how to use it better as you go along. We used CT angio images from patients who had been diagnosed with vasospasm after subarachnoid hemorrhage. By comparing these images side by side we were able to see where there was increased blood flow/vasoconstriction compared to normal vasculature.
