Nuclear Cardiology plays an essential role in assessing myocardial perfusion, ventricular function, ischemia and viability using noninvasive radionuclide imaging techniques. These modalities provide metabolic and physiological insights that complement anatomical imaging and help clinicians evaluate coronary artery disease, heart failure and microvascular dysfunction with exceptional accuracy. As innovations in molecular imaging, radiotracers and hybrid modalities advance rapidly, clinicians rely on specialised cardiology conference sessions to deepen their understanding of protocols, interpretation skills and emerging diagnostic technologies. Given its relevance to myocardial perfusion imaging, this session emphasises how nuclear techniques guide diagnosis, risk stratification and therapy planning.

The session explores core nuclear cardiology modalities including SPECT, PET, gated perfusion imaging and viability assessment. Participants learn how perfusion patterns reflect regional blood flow disparities, enabling differentiation between ischemia and infarction. PET imaging offers additional advantages including coronary flow quantification and metabolic assessment, enhancing diagnostic accuracy in complex or equivocal cases.

Attendees will examine tracer selection, pharmacologic stress agents and imaging protocols that influence diagnostic sensitivity. Case-based discussions highlight how to interpret attenuation artifacts, recognise balanced ischemia and integrate functional parameters such as ejection fraction, wall-motion abnormalities and transient ischemic dilation into clinical decision-making.

Nuclear cardiology also plays a crucial role in evaluating infiltrative diseases, inflammatory conditions and cardiomyopathies. Radiotracers assist in identifying amyloidosis, sarcoidosis and myocarditis, providing valuable insight into disease activity and guiding treatment timelines. Hybrid imaging—integrating PET/CT and PET/MRI—further enhances anatomical localisation and improves the accuracy of complex diagnoses.

As radiation safety is essential, the session discusses strategies to minimise dose exposure, optimise camera technology and adhere to regulatory requirements. New-generation high-efficiency imaging systems enable faster acquisition, lower doses and improved resolution. Innovations such as AI-assisted reconstruction and automated quantification support diagnostic consistency and reduce interpretation variability.

Future trends examined include novel myocardial blood-flow tracers, theranostic applications, targeted molecular imaging agents, advanced PET/MRI integration and AI-driven perfusion analysis that predicts risk more accurately than conventional metrics. This session provides a comprehensive understanding of how nuclear cardiology transforms modern cardiovascular evaluation and helps clinicians make informed clinical decisions.
