cerebral embolism, transcranial Doppler ultrasound, ischemic stroke


Cerebral embolism is one of common of ischemic stroke causes. Transcranial Doppler ultrasound can be used to detect cerebral embolism and help clinician to investigate other cause of stroke, apart from that transcranial Doppler ultrasound can be used to follow up intravenous thrombolysis and antithrombotic treatment in acute ischemic stroke patient.
