Open AccessRationale and design of the iCORONARY trial: improving the cost-effectiveness of coronary artery disease diagnosis
In patients with stable coronary artery disease (CAD), revascularisation decisions are based mainly on the visual grading of the severity of coronary stenosis on invasive coronary angiography (ICA). However, i...

Open AccessSystematic assessment of coronary calcium detectability and quantification on four generations of CT reconstruction techniques: a patient and phantom study
In computed tomography, coronary artery calcium (CAC) scores are influenced by image reconstruction. The effect of a newly introduced deep learning-based reconstruction (DLR) on CAC scoring in relation to othe...

Open AccessRight atrial and ventricular strain detects subclinical changes in right ventricular function in precapillary pulmonary hypertension
Right ventricular (RV) ejection fraction (EF) by cardiac magnetic resonance (CMR) correlates to outcome in precapillary pulmonary hypertension (pPH) patients, but is insensitive to early changes. Strain might ...
