Cardiology

The heart must go on: The spectrum of cardiological diseases ranges from arrhythmias to valve defects to heart attacks. However, the diagnostic means and the forms of therapy with intervention, surgery and medication are just as diverse. Read more about this affair of the heart here.

Nuclear cardiology – a nuclear perspective on matters of the heart

Nuclear cardiology is a specialised field in nuclear medicine that evaluates the heart function to help diagnosing conditions such as coronary artery disease and to assess treatment efficacy, whilst minimising invasive procedures like biopsies. More recently, clinicians have increasingly opted for nuclear imaging over endomyocardial biopsy to diagnose cardiac amyloidosis, allowing for earlier…
