Data‐Driven Feedback Identifies Focused Ultrasound Exposure Regimens for Improved Nanotheranostic Targeting of the Brain

Advanced Science, EarlyView.
ABSTRACT The blood‐brain barrier (BBB) renders the delivery of nanomedicine in the brain ineffective and the detection of circulating disease‐related DNA from the brain unreliable. Here, we demonstrate that microbubble‐enhanced focused ultrasound (MB‐FUS) mediated BBB opening, supported by large‐data models predict sonication regimens for safe and ...

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

Overview of Diagnostic Ultrasound Safety

Journal of Ultrasound in Medicine, EarlyView.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,

Bilateral Transcranial Doppler Monitoring During Neonatal Cardiac Surgery; Guidance for Clinical and Scientific Use

Pediatric Anesthesia, EarlyView.
ABSTRACT Introduction Neonates undergoing cardiac surgery face a high risk of neurological injury and neurodevelopmental complications. Transcranial Doppler monitoring is used and validated in adults to measure cerebral blood flow and can provide valuable insights into cerebral perfusion in neonates.

Resting Cerebrovascular Haemodynamics and Dynamic Assessment of Cerebrovascular Function in Polycystic Ovary Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Despite an increased cerebrovascular disease risk, the impact of Polycystic Ovary Syndrome (PCOS) on cerebrovascular haemodynamics and function is unknown. This study characterised cerebrovascular haemodynamics and function in women with PCOS versus healthy controls. Design Case‐control study.

Academic and cerebrovascular outcomes after neurodevelopmental screening in sickle cell disease: A longitudinal cohort study

Developmental Medicine &Child Neurology, EarlyView.
Neurodevelopmental screening in toddlers or preschoolers with sickle cell disease (SCD) predicts future academic deficits. Screening sensitivity for future academic deficits is highest in preschoolers with SCD. Brief neurodevelopmental screening tools can identify high risk children for early intervention. Abstract Aim To assess the predictive validity

Role of transcranial Doppler ultrasonography in stroke [PDF]

Postgraduate Medical Journal, 2007
AbstractTranscranial Doppler sonongraphy is a non-invasive, non-ionising, inexpensive, portable and safe technique that uses a pulsed Doppler transducer for assessment of intracerebral blood flow. This article deals with the principles and technique of transcranial Doppler sonography.
