"This technique is sometimes referred to, perhaps more accurately, as dynamic susceptibility contrast-enhanced MR perfusion, still abbreviated to DSC. This should not be confused with dynamic contrast-enhanced (DCE) MR perfusion, which relies on T1 shortening due to gadolinium-based contrast."

"Dynamic susceptibility contrast (DSC) MR perfusion is one of the most frequently used techniques for MRI perfusion, and relies on the susceptibility induced signal loss on T2*-weighted sequences which results from a bolus of gadolinium-based contrast passing through a capillary bed. The most commonly calculated parameters are rCBV, rCBF, MTT and Tmax 5."
