Compumedics DWL® has recently released an update of the Transcranial Doppler QL software V 3.6.8 . This update incorporates Z-score analysis of middle cerebral artery flow velocity within the NMA module.

A Z-score expresses how many standard deviations a given middle cerebral artery flow velocity measurement lies above or below the value expected for that age. Z-scores of different variables (Sys1, Sys2, D560 and HR) can be combined into a single radar plot to facilitate the rapid interpretation of intracranial hemodynamics in health and disease.
