Susceptibility-weighted imaging (SWI) is sensitive to susceptibility changes associated with blood and and shows excellent performance in detecting hemorrhage. Infants born preterm and those with congenital heart disease are at risk of parenchymal, cerebellar or intraventricular/ germinal layer haemorrhage.As such, there is a clinical need for rapid, high resolution SWI to assess brain injury in these infants.In this work a dedicated neonatal SWI protocol is proposed that aims to maximize the obtainable signal while minimizing the expected WM/GM contrast to improve sensibility to local field variations.
