Methodology for Jointly Assessing Myocardial Infarct Extent and Regional Contraction in 3-D CMRI [PDF]
IEEE Transactions on Biomedical Engineering, 2012, 59 (9),
pp.2650-2659, 2023 Automated extraction of quantitative parameters from Cardiac Magnetic Resonance Images (CMRI) is crucial for the management of patients with myocardial infarct. This work proposes a post-processing procedure to jointly analyze Cine and Delayed-Enhanced (DE) acquisitions in order to provide an automatic quantification of myocardial contraction and ...

Left ventricle ejection fraction and strain derived by three-dimensional echocardiography are associated with exercise capacity in the patients with heart failure [PDF]
Vojnosanitetski Pregled, 2019 Background/Aim. Echocardiography represents the most commonly performed noninvasive cardiac imaging tests for the patients with heart failure (HF). The aim of this study was to assess the relationship between the exercise capacity parameters [peak oxygen
