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.
