This documentation was last updated on for QLab 4.6.12. You can download a PDF version of this documentation by clicking here. If you’re brand new to QLab then we think Getting Started is probably a good place to get started! There’s a lot here, but you don’t need to read everything, or read in any particular order. However, LV volumes may be somewhat more underestimated with the current QLAB software version.Welcome to QLab! This documentation gives a comprehensive overview of the features and capabilities of QLab 4. RT3DE with TomTec or QLAB software analysis provides accurate LV-EF assessment in cardiomyopathic patients with distorted LV geometry and adequate 2D image quality. The analysis time was shorter with QLAB (4 +/- 2 minutes vs. Interobserver variability was 6.4 +/- 7.8% vs. Both programs accurately calculated LV ejection fraction (LV-EF) without a bias. LV-EDV and LV-ESV were significantly more underestimated with QLAB software. Also, an underestimated LV end-systolic volume (LV-ESV) for both TomTec (-4.8 +/- 9.9 mL) and QLAB (-8.5 +/- 14.2 mL) was found. Bland-Altman analysis revealed an underestimated LV end-diastolic volume (LV-EDV) for both TomTec (-9.4 +/- 8.7 mL) and QLAB (-16.4 +/- 13.1 ml). Off-line left ventricular (LV) volume analysis was performed with QLAB V4.2 (semiautomated border detection with biplane projections) and TomTec 4D LV analysis V2.0 (primarily manual tracking with triplane projections and semiautomated border detection).Įxcellent correlations (R(2) > 0.98) were found between MRI and RT3DE. To compare the interobserver variability and accuracy of two different real time three-dimensional echocardiography (RT3DE) analyzing programs.įorty-one patients (mean age 56 +/- 11 years, 28 men) in sinus rhythm with a cardiomyopathy and adequate 2D image quality underwent RT3DE and magnetic resonance imaging (MRI) within one day. ![]()
