Detection of cerebral vasculopathy in sickle cell disease using transcranial Doppler ultrasonography and magnetic resonance imaging. Case report.

, 1988
We describe a case of homozygous sickle cell anemia in which noninvasive transcranial Doppler ultrasonography and magnetic resonance imaging were used to detect angiographically documented occlusive lesions of intracranial arteries.

Cerebral artery dilatation maintains cerebral oxygenation at extreme altitude and in acute hypoxia : an ultrasound and MRI study [PDF]

, 2011
Transcranial Doppler is a widely used noninvasive technique for assessing cerebral artery blood flow. All previous high altitude studies assessing cerebral blood flow (CBF) in the field that have used Doppler to measure arterial blood velocity have ...

Association of the Transcranial Doppler Pulsatility Index, Central Pulse Pressure, and Pulse Wave Velocity with White Matter Hyperintensities in Patients with Acute Ischemic Stroke

Korean Journal of Clinical Laboratory Science
This retrospective single-center study examined whether the transcranial Doppler pulsatility index (PI), central pulse pressure (cPP), and pulse wave velocity (PWV) were associated with the white matter hyperintensity (WMH) severity in acute ischemic ...

EHA Guidelines on the management of children and adults with hemoglobin SC disease

HemaSphere, Volume 10, Issue 10, October 2026.
Abstract HbSC disease is the second most common type of sickle cell disease (SCD) in populations of African origin. Although it is often grouped together with other types of SCD, particularly sickle cell anemia (HbSS), it has unique pathophysiology and a different spectrum of laboratory and clinical features.

Ultrasound‐Guided Peripheral Venous Catheter for Automated Erythrocytapheresis in a Paediatric Population Affected by Sickle Cell Disease

eJHaem, Volume 7, Issue 5, October 2026.
ABSTRACT Introduction Automated erythrocytapheresis (aEEX) is an effective therapy for severe sickle cell disease (SCD). Its use in paediatrics can be limited by challenges in obtaining reliable venous access. Methods We conducted a retrospective, single‐centre study to evaluate the safety and feasibility of ultrasound (US)‐guided peripheral venous ...

Transcranial brain parenchyma sonography in movement disorders

Chinese Journal of Contemporary Neurology and Neurosurgery, 2012
The diagnosis and discrimination of movement disorders is very difficult in clinical medicine. We usually make a diagnosis according to symptoms and physical examination when the disease develops to a certain stage, but with few objective criteria ...

Role of Transcranial Doppler Ultrasonography in Detecting and Excluding Ischemic Stroke in the Emergency Department: A Prospective Observational Study [PDF]

Introduction: To determine whether color doppler ultrasonography (CDUS) and transcranial Doppler ultrasonography (TCD) can be used as an alternative test to cranial computed tomography angiography (CTA) by detecting vascular occlusions at the bedside in ...

Health Economic & Implementation Determinants of Prehospital Stroke Triage Tools: A Systematic Review

Journal of Evaluation in Clinical Practice, Volume 32, Issue 7, October 2026.
ABSTRACT Rationale Effective prehospital stroke triage enables faster treatment and better patient outcomes. Although prehospital triage innovations are rapidly emerging, evidence regarding the balance between costs and benefits as well as implementation issues remains limited.
