Assessment of left ventricular volumes using simplified 3-D echocardiography and computed tomography – a phantom and clinical study
OBJECTIVES To compare the accuracy of simplified 3-dimensional (3-D) echocardiography vs. multi-slice computed tomography (MSCT) software for the quantification of left ventricular (LV) volumes. DESIGN Three-D echocardiography (3-planes approach) and MSCT-CardIQ software were calibrated by measuring known volumes of 10 phantoms designed to closely mimic blood-endocardium interface. Subsequent...
متن کاملAssessment of global left ventricular function and volumes with 320-row multidetector computed tomography: A comparison with 2D-echocardiography
BACKGROUND Multidetector computed tomography (MDCT) has been demonstrated as a feasible imaging modality for noninvasive assessment of coronary artery disease and left ventricular (LV) function. Recently, 320-row systems have become available with 16 cm anatomical coverage allowing image acquisition of the entire heart within a single heartbeat. The purpose of this study was to evaluate the acc...
متن کاملAssessment of left ventricular volumes and ejection fraction with 16-slice multi-slice computed tomography; comparison with 2D-echocardiography.
BACKGROUND In recent years, multi-slice computed tomography (MSCT) has emerged as a rapidly expanding modality for non-invasive assessment of coronary artery disease. Simultaneously, left ventricular (LV) function can be evaluated although this is not yet a routine component of an MSCT examination. Accordingly, the purpose of the present study was to validate assessment of LV function with MSCT...
متن کاملQuantification of left ventricular volumes by two-dimensional echocardiography: a simplified and accurate approach.
A new and simplified method to determine left ventricular (LV) volumes with two-dimensional echocardiography (2-D echo) was developed using the parasternal long-axis and apical fourand twochamber views. An end-diastolic area (EDA) was derived using the longest minor axis (Dmax) from either of the three views and the major long axis (Lmax) from the apical views, with the formula EDA = Dmax * L T...
متن کاملleft ventricular volume and function assessment: a comparison study between echocardiography and ventriculography
conclusions despite the widespread use of 2d lvef and its good agreement with ventriculography, strain analysis seems to be more reliable as a quantitative tool for ventricular assessment. results the lvef values obtained by the two methods of ventriculography and echocardiography were not significantly different. the highest correlation regarding the echocardiographic lvef was obtained in the ...
