These results need to be taken into account when using STE analysis in the follow-up of cardiac children. In pediatrics, the Philips/GE inter-vendor level of variability in STE analysis is mainly due to inter ultrasound systems and inter sonographers' differences. This lesson will provide an overview of the tasks and controls that are used to complete accurate analysis of a 3D left.

QLAB PHILIPS SOFTWARE
Inter-analyzer variability was good especially for the global LV circumferential strain using Philips software (ICC of 0.78 ). Course description: This 90 minute Virtual Instructor Led Training (vILT) course is designed to empower the customer with the knowledge for navigating through the QLAB 3DQ Advanced software with a systematic approach. We observed poor inter-sonographer reliability for both global LV longitudinal strain and global LV circumferential strain with the two software systems. Traditional 510(k) QLAB Advanced Quantification Software Modifications of 6 Philips QLAB Advanced Quantification software (QLAB) is designed to view and quantify image data acquired on Philips ultrasound systems. Inter-ultrasound system correlation was poor for global longitudinal and circumferential LV strain (ICC of 0.34 ) and 0.12, respectively). For both software brands, the tracking quality was excellent in the LV longitudinal and circumferential displacements, but more limited in the RV free wall longitudinal strain. Conventional echocardiography variables were similar in both ultrasound systems. The feasibility was measured, and the tracking quality informed. Analyses were performed upon five levels of variability: intra/inter-ultrasound system, intra/inter-sonographer and intra/inter-analyzer.

Healthy children were screened for this prospective cross-sectional study. We aimed to evaluate the feasibility of STE analyses in healthy children and compare reliability of STE for left and right ventricles (LV, RV) between the EchoPAC (GE Healthcare) and the QLAB (Philips Healthcare) software systems. Speckle tracking echocardiography (STE) has become a useful tool in cardiology but remains scarcely developed in pediatrics.
