In clinical settings, dynamic susceptibility contrast (DSC) and dynamic contrast enhanced (DCE) data are rarely acquired together as both require a full single dose for optimal contrast-to-noise-ratio (CNR). However, both techniques offer complementary information that aid in the assessment of tumors. Current double acquisition methods acquire the DCE scan first with a half dose to minimize leakage effects in the subsequent DSC scan, compromising both scans. Here, we demonstrate the feasibility of an automatically switching DSC-DCE scan sequence by monitoring the signal intensity of the DSC scan, allowing acquisition of both datasets with a single contrast dose.
