Accuracy of subject-specific prediction of end-systolic time in MRI across a range of RR intervals. [PDF]
PLoS ONE, 2017 BACKGROUND:Prediction of End-Systole time is of utmost importance for cardiac MRI to correctly associate acquired k-space lines during reconstruction of cine acquisitions.

On the difficulty of finding spines [PDF]
, 2018 We prove that the set of symplectic lattices in the Siegel space $\mathfrak{h}_g$ whose systoles generate a subspace of dimension at least 3 in $\mathbb{R}^{2g}$ does not contain any $\mathrm{Sp}(2g,\mathbb{Z})$-equivariant deformation retract of ...

Probing cardiomyocyte mobility with multi-phase cardiac diffusion tensor MRI.
PLoS ONE, 2020 PurposeCardiomyocyte organization and performance underlie cardiac function, but the in vivo mobility of these cells during contraction and filling remains difficult to probe.

Investigating the effect of trigger delay on cardiac 31P MRS signals
Scientific Reports, 2021 The heart’s geometry and its metabolic activity vary over the cardiac cycle. The effect of these fluctuations on phosphorus (31P) magnetic resonance spectroscopy (MRS) data quality and metabolite ratios was investigated.

Cardiac Electromechanical Activity in Healthy Cats and Cats with Cardiomyopathies
Sensors, 2023 Optimal heart function depends on perfect synchronization between electrical and mechanical activity. In this pilot study, we aimed to investigate the electromechanical activity of the heart in healthy cats and cats with cardiomyopathy with ...

Estimation of elastic and viscous properties of the left ventricle based on annulus plane harmonic behavior [PDF]
, 2006 Assessment of left ventricular (LV) function with an emphasis on contractility has been a challenge in cardiac mechanics during the recent decades. The LV function is usually described by the LV pressurevolume (P-V) diagram. The standard P-V diagrams

Changes in left ventricular electromechanical relations during targeted hypothermia
Intensive Care Medicine Experimental, 2020 Background Targeted hypothermia, as used after cardiac arrest, increases electrical and mechanical systolic duration. Differences in duration of electrical and mechanical systole are correlated to ventricular arrhythmias.
