Validating new contrast-enhances sequences is problematic, as risks associated with gadolinium contrast agents generally preclude testing in healthy volunteers. The Dynamic Distributed Spirals trajectory (DDS) is a promising new dynamic susceptibility-contrast (DSC)-perfusion method. In this work, we show that DDS is capable of measuring the transient T2* changes induced by breathholding which are much lower in magnitude than the susceptibility changes induced by contrast agent transit in conventional DSC-perfusion experiments.
