Estimating ejection fraction by video-based AI

Can gallbladder ejection fraction measured by fatty meal cholescitigraphy diagnose chronic cholecystitis?

  Introduction: Despite presence of a body of evidence in support of high accuracy of cholecystokinin cholescintigraphy (CCK-CS) , for diagnosis of chronic cholecystitis(CC) , some authors have claimed that  gallbladder ejection fraction (GBEF)  has poor predictive diagnostic values. The purpose of this study was to determine if there is any difference in GBEF between...

Effect of Preoperative Ejection Fraction

Ninety-three patients with aortic valve disease were evaluated to determine the effect of the preoperative left ventricular ejection fraction (EF) on the results of aortic valve replacement (AVR). Forty-six patients had aortic stenosis (AS), 16 had aortic insufficiency (Al), and 31 had mixed aortic stenosis and insufficiency (MX). Immediate and long-term survival curves in AS and MX, and in AS ...

Left ventricular volumes and ejection fraction by echocardiography.

Determination of Cardiac Ejection Fraction by Electrical Impedance Tomography

where PV is the volume of blood pumped, that is given by the difference between the end-diastolic volume (EDV) and the end-systolic volume (ESV). Cardiac ejection fraction is a relevant parameter because it is highly correlated to the functional status of the heart. To determine the EF, different non-invasive techniques can be used, like echocardiography, cardiac magnetic resonance and computed...

Left ventricular ejection fraction by real-time three-dimensional echocardiography

Despite a staggering technical progress in echocardiography, in daily clinical practice assessment of left ventricular (LV) ejection fraction (EF) is still often done in a rather inaccurate two-dimensional (2D) manner. Real-time three-dimensional echocardiography (RT3DE) provides a more representative realistic view of LV volumes, thereby being the Necker cube for the naive realism of 2D method...
