International gestational age-specific centiles for umbilical artery Doppler indices: a longitudinal prospective cohort study of the INTERGROWTH-21st Project. [PDF]
, 2020 BACKGROUND: Reference values for umbilical artery Doppler indices are used clinically to assess fetal well-being. However, many studies that have produced reference charts have important methodologic limitations, and these result in significant ...

Intracranial Pressure and Pulsatility Index [PDF]
Neurosurgery, 2011 Idiopathic Normal Pressure Hydrocephalus (INPH) is a condition affecting gait, cognition and continence. Radiological examination reveals enlarged ventricles of the brain. A shunt that drains CSF from the ventricles to the abdomen often improves the symptoms.

Low Carotid Flow Pulsatility Index Correlates With the Presence of Unruptured Intracranial Aneurysms
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021 Background We assessed cases of incidental unruptured intracranial aneurysm (UIA) discovered on screening magnetic resonance angiography to identify hemodynamic and atherosclerotic risk factors. Methods and Results The data of 1376 healthy older subjects

Role of Uterine Artery Doppler at 11-14 Weeks of Pregnancy in Early Prediction of Preeclampsia: A Prospective Cohort Study [PDF]
Journal of Clinical and Diagnostic Research, 2022 Introduction: Doppler ultrasonography, by comparing systolic and diastolic waveforms helps in assessment of uteroplacental circulation. Since preeclampsia has ethnic and geographical variations, it is important to understand the prediction modalities in ...

Doppler Pulsatility Index in Spontaneous Intracerebral Hemorrhage [PDF]
European Neurology, 2013 <b><i>Background and Purpose:</i></b> Elevated intracranial pressure (ICP) as a result of intracerebral hemorrhage (ICH) and perihematomal edema often leads to tissue shift, which can be identified in cross-sectional imaging and presents a known predictor of functional outcome.

4.2 Biological and Vascular Contributors to Cerebral Pulsatility and Pulsatile Damping
Artery Research, 2020 Cerebral pulsatility is an emerging contributor to brain health that reflects the balance between the transmission and damping (i.e. attenuation) of pulsatility through extracranial vessels into the cerebrovasculature.

Association between trunk flexibility and renal flow pulsatility in middle-aged and older adults
Experimental Gerontology, 2023 Background: Recent clinical studies have indicated that poor trunk flexibility is associated with arterial stiffness in the aged. Arterial stiffness leads to elevated renal flow pulsatility, which accelerates age-related renal dysfunction and damages ...

Aerobic exercise training enhances cerebrovascular pulsatility response to acute aerobic exercise in older adults [PDF]
, 2018 The brain\u27s low resistance ensures a robust blood flow throughout systole and diastole and is susceptible to flow pulsatility. Increased cerebral pulsatility contributes to the progression of cerebrovascular disease.

Clinical application of pulsatility index
Medical Research Journal, 2020 Pulsatility index (PI) is defined as the difference between the peak systolic flow and minimum diastolic flow velocity, divided by the mean velocity recorded throughout the cardiac cycle. It is a non-invasive method of assessing vascular resistance with the use of Doppler ultrasonography.

Effect of Acute Resistance Exercise on Carotid Artery Stiffness and Cerebral Blood Flow Pulsatility
Frontiers in Physiology, 2014 Arterial stiffness is associated with cerebral flow pulsatility. Arterial stiffness increases following acute resistance exercise (RE). Whether this acute RE-induced vascular stiffening affects cerebral pulsatility remains unknown.
