Middle Cerebral Artery Pulsatility Index as Predictor of Cognitive Impairment in Hypertensive Patients

Pulsatility index in the middle cerebral artery- associated with cognitive impairment in lacunar stroke?

Predictive Value of Middle Cerebral Artery to Uterine Artery Pulsatility Index Ratio in Hypertensive Disorders of Pregnancy

Aims and Objectives. (i) To determine the predictive value of cerebrouterine (CU) ratio (middle cerebral artery to uterine artery pulsatility index, MCA/UT PI) in assessing perinatal outcome among hypertensive disorders of pregnancy. (ii) To compare between CU ratio and CP ratio (MCA/Umbilical artery PI) as a predictor of adverse perinatal outcome. Methods. A prospective observational study was...

Fetal middle cerebral artery and umbilical artery pulsatility index: effects of maternal characteristics and medical history.

OBJECTIVE To define the contribution of maternal variables which influence the measured fetal middle cerebral artery (MCA) and umbilical artery (UA) pulsatility index (PI) in the assessment of fetal wellbeing. METHODS Maternal characteristics and medical history were recorded and fetal MCA-PI and UA-PI (n = 36,818) were measured in women with singleton pregnancies attending a routine hospital...

Sensitivity and Specificity of Pulsatility Index Umbilical Artery and Middle Cerebral Artery in Detecting Intra Uterine Growth Restriction

Objective: To determine the sensitivity and specificity of the pulsatile index in umbilical artery (PI-UA) and pulsatile index in middle cerebral artery (PI-MCA) in detecting IUGR by comparing it with the birth weight. Study Design: Validation study. Place and Duration of Study: Study was conducted in Department of Radiology, Military Hospital and Combined Military Hospital Rawalpindi, which wa...

Arterial pulsatility as an index of cerebral microangiopathy in diabetes.

BACKGROUND AND PURPOSE This study was designed to evaluate cerebral hemodynamic changes related to diabetes mellitus (DM) with transcranial Doppler ultrasonography (TCD). METHODS We measured the flow velocities and the Gosling pulsatility index (PI) of the middle cerebral artery (MCA), extracranial internal carotid artery (ICA), and basilar artery (BA) in 56 stroke-free, normotensive patients...
