PRACTICE PARAMETERAlUM Practice Parameter for thePerformance of Transcranial DopplerUtrasoundIntroductionY he American Institute of Ultrasound in Medicine (AIUM)is a multidisciplinary association dedicated to advancingthe safe and effective use of ultrasound in medicinethrough professional and public education,research,developmentof clinical practice parameters,and accreditation of practicesperforming ultrasound examinations.The AIUM Practice Parameter for the Performance of Trans-cranial Doppler Ultrasound was revised by the AIUM in collabora-tion with other organizations whose members use ultrasound forperforming this examination(s)(see "Acknowledgments").Rec-ommendations for personnel requirements,the request for theexamination,documentation,quality assurance,and safety mayvary among the organizations and may be addressed by eachseparately.This Practice Parameter is intended to provide the medicalultrasound community with recommendations for the perfor-mance and recording of high-quality ultrasound examinations.Theparameters reflect what the AIUM considers the appropriatecriteria for this type of ultrasound examination but is not intendedto establish a legal standard of care.Examinations performed inthis specialty area are expected to follow the parameter with recog-nition that deviations may occur depending on the clinicalsituation.Transcranial Doppler ultrasound (TCD)is a noninvasivetechnique that assesses blood flow within the circle of Willis andthe vertebrobasilar system.IndicationsA.Indications for a TCD examination of children and adultsinclude but are not limited to:1.Evaluation of sickle cell disease to determine strokeReceived April 3,2023.Manuscript acceptedrisk.1-3for publication April 4,2023.2.Detection and follow-up of stenosis or occlusion of amajor intracranial artery including monitoring and potenti-dai:10.1002/jum.16234ation of thrombolytic therapy for acute stroke patients-2023 American Institute of Ultrasound in Medicine.J Ultrasound Med 2023;9999:1-90278-4297 www.aium.org
