Relative bias = (parametermethod-parameter 3DQA)/parametermethod; percentage error = LOA/mean value of parameter measured by studied method and 3DQA. 3DQA: Advanced cardiac three-dimensional quantification; LOA: Limits of agreement; HM-RE: HeartModel with regional endocardial border editing; LVEDV: Left ventricular end-diastolic volume; LVESV: Left ventricular end-systolic volume; LVEF: Left ventricular ejection fraction; LAESV: Left atrial end-systolic volume; DCM: Dilated cardiomyopathy; SWMA: Segmental wall motion abnormality; HCM: Hypertrophic cardiomyopathy.
