Clinical use of A- and B-mode echoencephalography in neurology, neurosurgery, and pediatrics is discussed, and some results are presented. Descriptions are given of several techniques to obtain two-dimensional echoencephalographic pictures. Two-dimensional echoencephalography can be particularly helpful with hydrocephalic babies. Recording techniques for pulsatile echoencephalography and the factors influencing the shape of cerebral echo pulsations are considered. Also, the diagnostic value of pulsatile echoencephalography in several brain diseases is discussed.

Transcranial Doppler Arterial Pressure Gradient Is Associated With Delayed Infarction After Subarachnoid Hemorrhage.
J Neuroimaging
January 2025
Department of Neurology, Georgetown University School of Medicine, Washington, District of Columbia, USA.
Background And Purpose: While the pulsatility index (PI) measured by transcranial Doppler (TCD) has broader associations with outcomes in neurocritical care, its use in monitoring delayed cerebral infarction (DCI) in patients with aneurysmal subarachnoid hemorrhage (SAH) is not endorsed by current clinical guidelines. Recognizing that arterial pressure gradient (ΔP) can be estimated using PI, we investigated the potential significance of TCD-estimated ΔP.
Methods: In this observational study of 186 SAH patients, we recorded the mean cerebral blood flow velocity (mCBFV) and PI values from the middle cerebral artery, along with corresponding blood pressures.
Norepinephrine titration in patients with sepsis-induced encephalopathy: cerebral pulsatility index compared to mean arterial pressure guided protocol: randomized controlled trial.

Background: Although surviving sepsis campaign (SSC) guidelines are the standard for sepsis and septic shock management, outcomes are still unfavourable. Given that perfusion pressure in sepsis is heterogeneous among patients and within the same patient; we evaluated the impact of individualized hemodynamic management via the transcranial Doppler (TCD) pulsatility index (PI) on mortality and outcomes among sepsis-induced encephalopathy (SIE) patients.
Methods: In this prospective, single-center randomized controlled study, 112 patients with SIE were randomly assigned.

Background: Antihypertensives (AHD) can influence cerebral autoregulation (CA) and attenuate hypertrophic concentric remodelling of arterioles. The aim of this study was to examine the associations between AHD, CA and structural and functional properties of cerebral arteries.
Methods: In this observational, cross-sectional study 115 volunteers were divided in group 1 (non-hypertensive) [n = 30]; group 2 (hypertensive with systolic blood pressure [SBP] < 140 and diastolic blood pressure [DBP] < 90 mmHg) [n = 54]; group 3 (hypertensive with SBP ≥ 140 or DBP ≥ 90 mmHg) [n = 31] and simultaneous measurements of systemic blood pressure (BP) and middle cerebral artery blood flow velocity (CBFV) were obtained from digital plethysmography and transcranial Doppler.
Longitudinal assessment of transcranial Doppler imaging in children with sickle cell disease without neurological symptoms.

Introduction: Stroke is one of the most devastating complications of sickle cell disease (SCD). Transcranial Doppler Imaging (TCDI) is the least invasive screening method to predict patients at risk for developing stroke in the disease. After a 10-year follow-up, we longitudinally assessed the TCDI in children with SCD without neurological symptoms.

Previous research has shown that blood flow abnormalities affect major depressive disorder (MDD) from multiple perspectives. Therefore, this study aims to investigate the relationship between middle cerebral artery (MCA) blood flow velocity parameters and clinical symptom scores (Hamilton Depression Rating Scale [HAMD] and Montgomery-Åsberg Depression Rating Scale [MADRS]) in patients with MDD. We compared the MCA blood flow velocity parameters, including peak systolic velocity (MCA-PSV), end-diastolic velocity (MCA-EDV), and mean velocity (MCA-MV), between 50 MDD patients and 50 control subjects.
