FOREWORD
Cardiovascular disease is a major contributor to premature morbidity and mortality worldwide, and
improving human health through early and effective diagnostic imaging is an effective means to positively
influence the health of a population. Through efforts within the IAEA, numerous initiatives have been
developed, or are underway, to promote quality medical imaging practices for the detection and guided
treatment of cardiovascular disease. These regional and global training and educational programmes
emphasize the importance of worldwide standards for instrumentation, protocols, appropriate use, and
high quality image interpretation and reporting practices.
The importance of addressing cardiovascular diseases and other non-communicable diseases is
recognized by United Nations organizations. Under United Nations Sustainable Development Goal 3, to
ensure healthy lives and to promote well being for everyone at all ages, the target is to reduce premature
non-communicable disease mortality by one third by 2030. The Global Action Plan, designed by the
World Health Organization, aims at preventing and controlling non-communicable diseases and offers a
roadmap and policy options. The aim is to prevent heart attacks and strokes and to achieve a 25% relative
reduction in premature mortality from non-communicable diseases by 2025.
Integrated cardiovascular imaging is an evolving concept. Recent advances in technology have
contributed to the development of new imaging modalities and the refinement of existing ones, leading to
major improvements in the accuracy of diagnosing cardiovascular and other diseases. While modality
centric knowledge and expertise have been the primary drivers of improvement in each modality, this has
also contributed to imagers working in silos, which has resulted in limited intermodality coordination and
collation of information relevant for patient care. Non-invasive imaging tools to diagnose and stratify risk
in cardiac disease and to guide its management include echocardiography, coronary computed tomography
angiography (CCTA), cardiac magnetic resonance (CMR) imaging and nuclear cardiology, using either
single photon emission computed tomography (SPECT) or positron emission tomography (PET) coupled
with computed tomography (CT). Each of these techniques has distinct characteristics that allow the
evaluation of details of the anatomy of the heart, its physiology or both. Depending on a patient’s
characteristics and the various potential clinical presentations, some of these techniques may be better
suited for some patients than other techniques, either for the initial work-up of a certain condition or as a
follow-up method to evaluate a condition already identified.
The IAEA plays an integral role in the development of clinical trial evidence and in the development
of guidance documents to synthesize available data into optimal strategies of care. Examples of IAEA
sponsored research can be found in recent publications.
The availability of technology is quite heterogeneous worldwide. Some countries have access to only
the most basic tools to evaluate the heart, such as electrocardiogram, exercise treadmill/bicycle test and
echocardiography. Other countries have various degrees of access to more advanced imaging
technologies, such as SPECT, CCTA, CMR imaging and PET–CT. It is advisable that physicians use all
the diagnostic potential of any techniques available, applying internationally accepted standard protocols,
and that the results be interpreted and acted upon appropriately.
This publication provides comprehensive guidance on the rationale for and implementation of
integrated cardiovascular imaging for practitioners. Imaging experts can embrace optimal strategies of
cardiovascular imaging to address an array of clinical conditions. By applying high quality evidence
published in peer reviewed literature, vast opportunities are available to improve the lives of patients at
risk of and diagnosed with cardiovascular disease, many of whom will benefit from the use of
cardiovascular imaging to guide optimal therapeutic decision making.
