Our team advances multimodality cardiac imaging — PET, SPECT, cardiac CT and MRI — to make the diagnosis of heart disease more precise, more personalised, and less invasive. We combine excellence in patient care with internationally recognised clinical and translational research.
Cardiovascular disease remains the leading cause of death worldwide. At the Department of Nuclear Medicine of the University Hospital Zurich, our Cardiac Imaging group develops and validates imaging strategies that improve the diagnostic and prognostic value of non-invasive tests — so that the right patient receives the right test at the right time, while avoiding unnecessary invasive procedures.
A high-volume referral centre for myocardial perfusion imaging (SPECT & PET), coronary CT angiography, cardiac MRI and hybrid imaging, serving patients across Switzerland.
From quantitative myocardial blood flow and photon-counting CT to artificial intelligence and 3D modelling, our research bridges physics, physiology and patient outcomes.
We train the next generation of cardiac imagers and share reproducible tools with the wider community, including our open CH-CACS coronary calcium calculator.
Practical resources developed by our group and used in routine care and research.
The Swiss coronary artery calcium score calculator — estimate cardiovascular risk from a CT calcium score with percentile reference data.
Pre-test likelihood of relevant coronary stenosis from age, sex, risk factors, symptoms and medication — a bedside aid for selecting the right downstream test. This model is preliminary, has not yet been externally validated, and is intended for research use only.
Turns coronary CT measurements — lesion geometry, calcium burden, ostial anatomy — into a structured pre-procedural plan with catheter, sizing and C-arm projection suggestions.
Secure electronic data capture for our clinical studies and registries. Access is restricted to authorised study collaborators.
Our group runs one of the first clinical programmes evaluating silicon-based photon-counting computed tomography for coronary imaging — pushing spatial resolution and radiation efficiency to new limits.
