Standardized evaluation methodology for renal cortical blood perfusion in elderly patients using contrast‐enhanced ultrasound: A Chinese expert consensus (2024 edition)

Aging Medicine
As a sensitive and non‐invasive method for assessing changes in renal cortical blood perfusion in the elderly, contrast‐enhanced ultrasound (CEUS) can indirectly reflect changes in kidney filtration and reabsorption function, thus providing feasibility ...

Magnetic Resonance Imaging–Derived Renal Oxygenation and Perfusion During Continuous, Steady‐State Angiotensin‐II Infusion in Healthy Humans

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe role of kidney hypoxia is considered pivotal in the progression of chronic kidney disease. A widely used method to assess kidney oxygenation is blood oxygen level dependent (BOLD)–magnetic resonance imaging (MRI), but its interpretation ...

Toward Automation of the Supine Pressor Test for Preeclampsia [PDF]

, 2019
Preeclampsia leads to increased risk of morbidity and mortality for both mother and fetus. Most previous studies have largely neglected mechanical compression of the left renal vein by the gravid uterus as a potential mechanism.

Dopplerfluxometria das artérias renais: valores normais das velocidades sistólica e diastólica e do índice resistivo nas artérias renais principais Renal arteries Dopplerfluxometry: normal systolic and diastolic flow velocities and resistive index values in the main renal arteries

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2006
Dopplerfluxometry of renal arteries has been used to estimate renal perfusion in humans. The aim of this study was to use Dopplerfluxometry technique to calculate the resistive index of main renal arteries in dogs, measuring their systolic and diastolic ...

Noninvasive characterization of renal artery blood flow

Kidney International, 1981
Noninvasive characterization of renal artery blood flow variables in the human has not been reported. Using a unique dual-frequency real-time two-dimensional echo Doppler (Duplex scanner) that was calibrated in vitro, we characterized renal artery blood flow patterns in 16 normal subjects (6 females).
