EDITORIAL
Afshin Farzaneh-Far, Raymond Y Kwong
Recent introduction of hybrid positron emission tomography/magnetic resonance (PET/MR) scanners has created excitement regarding potential applications in cardiovascular medicine. This has led to a number of optimistic assessments of its potential value in the nuclear cardiology literature, although most published data are still at the feasibility or pre-clinical level. Such excitement is understandable and provides "fuel" for generation of the necessary clinical validation studies, which will be required. Given the current scrutiny from payers and government agencies to reduce the costs of cardiac imaging, the responsibility for showing additive benefit lies on the shoulders of those advocating for new, more expensive technologies...

Quantitative analysis of myocardial perfusion Single photon emission computerized tomography (SPECT) images is increasingly applied in modern nuclear cardiology practice, assisting in the interpretation of myocardial perfusion images (MPI). There are different extensively validated state-of-the-art software packages, including QPS (cedars-Sinai), Corridor 4DM (University of Michigan) and Emory cardiac toolbox (Emory university), providing highly accurate and reproducible data. However, these software packages may suffer from potential artifacts related to patient or technical factors...

In the 2015 guidelines of the European Society of Cardiology (ESC) and the American Heart Association (AHA) on infective endocarditis, the diagnostics are based on the modified Duke criteria. The diagnosis can be confirmed by a combination of micro-organisms demonstrated in culture or in situ, with the detection of valvular lesions or abscess formation by an imaging modality using echocardiography, positron emission tomography computed tomography (PET/CT), cardio-CT or nuclear medical methods. The management should be further improved by an interdisciplinary endocarditis team in a specifically designated reference center...

Chemotherapy-induced cardiotoxicity (CTX) is a determining factor for the quality of life and mortality of patients administered potentially cardiotoxic drugs and in long-term cancer survivors. Therefore, prevention and early detection of CTX are highly desirable, as is the exploration of alternative therapeutic strategies and/or the proposal of potentially cardioprotective treatments. In recent years, cardiovascular imaging has acquired a pivotal role in this setting. Although echocardiography remains the diagnostic method most used to monitor cancer patients, the need for more reliable, reproducible and accurate detection of early chemotherapy-induced CTX has encouraged the introduction of second-line advanced imaging modalities, such as cardiac magnetic resonance (CMR) and nuclear techniques, into the clinical setting...

Cardiovascular implantable electronic device (CIED) infection and prosthetic valve endocarditis (PVE) remain a diagnostic challenge. Cardiac imaging plays an important role in the diagnosis and management of patients with CIED infection or PVE. Over the past few years, cardiac radionuclide imaging has gained a key role in the diagnosis of these patients, and in assessing the need for surgery, mainly in the most difficult cases. Both (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) and radiolabelled white blood cell single-photon emission computed tomography/computed tomography (WBC SPECT/CT) have been studied in these situations...

There are interesting differences between the practice of Nuclear Cardiology in Japan and that in the United States and associated unique challenges. Differences in patient body habitus and the perceived importance of limiting patient radiation dose have resulted in different radiopharmaceutical and imaging protocol preferences. Governmental approval and reimbursement policies for various radiopharmaceuticals have promulgated adoption of different clinical applications. Both countries have experienced a significant decline in the number of nuclear cardiology studies performed, in part due to decreased governmental funding and reimbursement and to the emergence of competing modalities...

Radionuclide myocardial perfusion imaging (MPI) is a large component of the healthcare spending both in developed and developing countries. MPI is also responsible for a significant increase in the exposition of patients and health care operators to ionizing radiations for medical purposes. Thus, health-care systems and pertinent scientific societies were involved in developing criteria to contain the non-appropriate use by implementing Appropriate Use Criteria and Clinical Indications Guidelines. The present manuscript will review the concept and limitations of such an approach...

Risk prediction through integration of clinical variables and imaging data into a prognostic model can identify those factors with a high impact on patient outcome. The development of a prognostic model traditionally includes the evaluation of the independent contribution of variables with consideration of covarying factors that may confound risk stratification. Several methods and metrics are available to assess the performance of a prediction model. Traditional measures for binary and survival outcomes include the concordance (C) statistic for discriminative ability, and goodness-of-fit statistics for calibration...

The burden of cardiovascular diseases (CVDs) in the world is ever growing. They represent the first cause of death worldwide and in Latin America. Nuclear cardiology has a well-established role in the management of patient with CVDs and is being increasingly integrated into the healthcare systems in the region. However, there remains variability as to the infrastructure available across the countries, in terms of existing technology, radiopharmaceuticals, and human resources. The approximate number of gamma (γ) cameras in the region is 1348, with an average of 2...

Nuclear cardiology is one of the major fields of nuclear medicine practice. Myocardial perfusion studies using single-photon emission computed tomography (SPECT) have played a crucial role in the management of coronary artery diseases. Positron emission tomography (PET) has also been considered an important tool for the assessment of myocardial viability and perfusion. However, the recent development of computed tomography (CT)/magnetic resonance imaging (MRI) technologies and growing concerns about the radiation exposure of patients remain serious challenges for nuclear cardiology...
