Coronary Computed Tomography Angiography (CCTA) is a rapidly expanding cardiac imaging modality which can combine anatomical and functional cardiac imaging information. The ability to assess coronary artery wall structure, luminal narrowing, congenital coronary artery variants, myocardial and valvular pathology, post-cardiothoracic surgical changes and congenital heart disease non invasively is attractive.

Reduction in radiation dose remains a challenge for both modalities but newer acquisition and processing technology will reduce dose.

Common elements are shared in the approach to CCTA and Cardiac SPECT with attenuation correction. Training in Nuclear Cardiology gives a translational knowledge base that needs additional expansion to master CCTA.

Patient preparation; knowledge of cross-sectional anatomy; 3-dimensional imaging of the heart experience and use of advanced workstation programmes for CCTA interpretation are common skills shared in both radiology and molecular imaging communities.

Additional knowledge regarding ECG gating techniques, contrast bolus design, pre-procedure medication and post-procedure reconstruction techniques is required and can be achieved in targeted learning environments.

A shared training approach will offer the best skill mix in expanding access to CCTA. Appropriate credentialing and training pathways are being developed in Australia.
