DSC

•

DCE – Advantages :

•

• ability to examine the brain microvasculature ≠ from DSC • quantitative assessment of the blood-brain barrier and microvascular permeability. • more complete assessment of brain tumor angiogenesis. • High SNR – Disadvantages • complexity in image acquisition and pharmacokinetic model postprocessing, • user-dependence, • lack of widely available and easy-to-use postprocessing software. • ASL
