Validation and Development of a New Automatic Algorithm for Time-Resolved Segmentation of the Left Ventricle in Magnetic Resonance Imaging

Table 1

Clinical parameters in test set. Results for clinical parameters in the full test set () as differences between automatic segmentation and manual delineation.

	Absolute difference	Relative difference	value
EDV	−11 ± 11 mL	−6 ± 6%	<0.01
ESV	1 ± 10 mL	1 ± 13%	0.57
EF	−3 ± 4%	−5 ± 7%	<0.01
LVM	4 ± 15 g	4 ± 14%	0.07
SV	−12 ± 8 mL	−11 ± 8%	<0.01
CO	−0.7 ± 0.5 L/min	−11 ± 8%	<0.01

Absolute and relative values are expressed as mean ± SD. EDV = end-diastolic volume, ESV = end-systolic volume, EF = ejection fraction, and LVM = left ventricular mass.
