An Analysis of Resting-State Functional Transcranial Doppler Recordings from Middle Cerebral Arteries [PDF]
, 2013 Functional transcrannial Doppler (fTCD) is used for monitoring the hemodynamics characteristics of major cerebral arteries. Its resting-state characteristics are known only when considering the maximal velocity corresponding to the highest Doppler shift (

Changing ethnic disparity in ischemic stroke mortality in US children after the STOP trial. [PDF]
, 2013 ImportanceA prior report showed higher stroke mortality in US black children compared with white children (1979-1998), a disparity likely due in part to sickle cell disease, which leads to a high risk of childhood ischemic stroke.
