Comparison of perfusion techniques
•
DSC
–
Advantages :
•
the most widely used method to measure brain perfusion with MRI.
•
The software to postprocess these data is widely available and relatively
straightforward to use.
•
DSC-derived relative CBV is the most widely used and robust method to
evaluate brain tumors.
•
High SNR : whole brain < 1mn
–
disadvantages
•
difficulty in determining absolute quantification,
•
susceptibility artifacts (i.e., blood product, calcification, metal, air, and
bone)
•
DCE
•
