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.

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 ...

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

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 ...

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.

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.

Fetal Ductus Venosus Pulsatility Index and Diameter during Second and Third Trimester of Gestation
Journal of Nepal Medical Association, 2017 Introduction: The ductus venosus is a small funnel shaped vessel found posterior to the fetal liver connecting the intra-abdominal umbilical vein and the inferior vena cava. It is one of the three physiological shunts in the fetus.

Artery Research, 2020 Background: Higher cerebral blood flow (CBF) pulsatility was found to be associated with severer brain white matter lesions in the elderly [1]. It was hypothesized that the central/elastic arterial stiffness/compliance may directly affect CBF pulsatility.

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.
