Quantification of left ventricular volumes and function in anesthetized beagles using real-time three-dimensional echocardiography: 4D-TomTec™ analysis versus 4D-AutLVQ™ analysis in comparison with cardiac magnetic resonance imaging

Table 3 Comparison of measurement duration

Method	Mean	SD	Min	Max
4D-TomTec™	214.94	46.06	118.00	306.00
4D-AutLVQ™ with manual correction	145.21	57.03	72.00	365.00
4D-AutLVQ™ without manual correction	48.54	23.10	24.00	125.00

Mean and standard deviation (SD) as well as minimum (Min) and maximum (Max) of analyzing time needed to perform a volumetric measurement in 10 healthy anesthetized beagles needed by two different three-dimensional echocardiography based volumetric analyzing software programs (sec = seconds). Furthermore analysis time of 4D-AutLVQ™ without manual correction. There is a significant (P < 0.0001) difference between each method
