Bolus characteristics based on Magnetic Resonance Angiography

BioMedical Engineering OnLine, 2006
Background A detailed contrast bolus propagation model is essential for optimizing bolus-chasing Computed Tomography Angiography (CTA). Bolus characteristics were studied using bolus-timing datasets from Magnetic Resonance Angiography (MRA) for adaptive ...
