BACKGROUND Gut mucosal blood flow measurement is used to study a variety of disorders and possibly extrinsic neural function. AIMS To determine optimal measurement criteria and validate this technique ...

What is a Doppler ultrasound? This noninvasive diagnostic test uses high-frequency sound waves to determine the speed and direction of blood flow in the heart. It is helpful in indicating the presence ...

Department of Medical Physics, Bristol and Weston Health Authority. The volume flow rate of blood in the portal vein was measured using a duplex ultrasound system. The many errors inherent in the ...

Ultrasound scans are safe and painless. A transcranial Doppler ultrasound uses sound waves to evaluate blood flow (blood circulation) in and around the brain. The test is also called transcranial ...

However, successful restoration of epicardial blood flow does not guarantee restoration of flow at the myocardial tissue level. The incidence of inadequate myocardial reperfusion after primary ...

Aletta's advanced features include an AI-driven Doppler ultrasound and imaging technology for accurate vein detection; a ...

A non-invasive method of CPP measurement has previously been reported based on waveform analysis of blood flow velocity measured in the middle cerebral artery (MCA) by transcranial Doppler. This study ...

AIMS To evaluate whether serial Doppler measurements of superior mesenteric artery (SMA) blood flow velocity after the first enteral feed could predict early tolerance to enteral feeding in preterm ...

However, flow measurements in the superior vena cava (SVC) can assess blood returning from the upper body and brain. OBJECTIVES To describe a Doppler echocardiographic technique that measures blood ...

ohsu.edu Aim To assess total retinal blood flow (TRBF) in diabetic retinopathy (DR) using multiplane en face Doppler optical coherence tomography (OCT). Conclusion The novel multiplane en face Doppler ...
