The use of susceptibility weighted imaging (SWI) in hypoxic-ischemic encephalopathy (HIE) can give additional information about the varying amounts of deoxyhemoglobin in cerebral veins as an indicator of metabolic stress. Abnormal levels of deoxyhemoglobin (low or high) are correlated with poor clinical outcome. This work compares different qualitative and quantitative measures of venous visibility as an indicator of deoxyhemoglobin levels and how it correlates with clinical outcome.
