The authors characterized lesion changes on quantitative susceptibility mapping and R2* at various gadoliniumenhancementstages (nodular, shell-like, nonenhancing) in 64 patients with 203 lesions. They found that: 1) active MS lesions with nodular enhancement show R2* decrease but no quantitative susceptibility mapping change; 2) late active lesions with peripheral enhancement show R2* decrease and quantitative susceptibility mappingincrease in the lesion center; and 3) nonenhancing lesions show both quantitative susceptibility mapping and R2* increase, reflecting iron accumulation.

The authors retrospectively studied clinical and radiologic data of 333 consecutive patients with aneurysmal SAH between January 2009 and December 2011. Adjusted odds ratios werecalculated for the association between automatically quantified total blood volume on NCCT and delayed cerebral ischemia (clinical, radiologic, and both). The adjusted OR of total blood volume for delayed cerebral ischemia was 1.02 per milliliter of blood. They conclude that a higher total blood volume measured with the automated quantification method is significantly associated with delayed cerebral ischemia.

The authors evaluated MRIs performed before hospital discharge in 53 infants with congenital diaphragmatic hernia that were scored forbrain injury by 2 pediatric neuroradiologists. Potential associations with perinatal and clinical variables from the neonatal intensive care unit stay were probed. The most common findings were enlarged extra-axial spaces (36%), intraventricular hemorrhage (23%), ventriculomegaly (19%), white matter injury (17%), and cerebellar hemorrhage (17%). Brain injury score was associated with extracorporeal membrane oxygenation, lack of oral feeding at discharge, use of inotropes, and gastrostomy tube placement before hospital discharge.
