Clinical application of pulsatility index [PDF]

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.

Arterial Pulsatility Index values for prediction of aneurysm

2015 Medical Technologies National Conference (TIPTEKNO), 2015
Blood flow is pulsatile and and the pulsatility is essential to maintain vessel wall function. Pulsatility Index is measures of vascular resistance. Phase contrast technique is used to determine blood flow quantification in cerebrovascular and cardiovascular pathologies.

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.

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.
