Reference Ranges for LVEF and LV Volumes
Electrocardiographic gating is increasingly used for 82Rb cardiac PET/CT, but reference ranges for global functional parameters are not well defined. We sought to establish reference values for left ventricular ejection fraction (LVEF), end systolic volume (ESV), and end diastolic volume (EDV) using 4 different commercial software packages. Additionally, we compared 2 different approaches for t...

متن کاملSimultaneous LV and RV volumes by conductance catheter: effects of lung insufflation on parallel conductance.
One aspect in the measurement of ventricular volume using the conductance catheter technique is the assessment of parallel electrical conductivity of structures extrinsic to the ventricular blood pool. Because it is sometimes necessary to make volume measurements during ventilation or spontaneous respiration, the extent to which parallel conductance may vary with lung insufflation was investiga...
متن کاملQuantification of LV Volumes with 4D Real-Time Echocardiography
This paper presents a new 4D (3D + Time) expansion of echocardiographic volumes on complex exponential wavelet-like basis functions called Brushlets [1]. Brushlet functions offer good localization in time and frequency and decompose a signal into distinct patterns of oriented textures, invariant to intensity and contrast range. Automatic left ventricle (LV) endocardial border detection is carri...
متن کاملStatistical agreement of left ventricle measurements using cardiac magnetic resonance and 2D echocardiography in ischemic heart failure
BACKGROUND The aim of this study was to compare cardiac magnetic resonance imaging (CMR) with 2-dimensional echocardiography (2D echo) in the assessment of left ventricle (LV) function parameters and mass in patients with ischemic heart disease and severely depressed LV function. Although 2D echo is commonly used to assess LV indices, CMR is the state-of-the-art technique. Agreement between the...
