In the realm of modern medicine, the integration of advanced technologies has revolutionized diagnostic and therapeutic approaches, particularly in the field of cardiology. Among these innovations, nuclear cardiology stands out as a pivotal tool in the assessment and management of cardiovascular diseases (CVDs). Utilizing radiopharmaceuticals and imaging techniques, nuclear cardiology provides valuable insights into the physiological and pathological processes of the heart, enabling clinicians to make informed decisions regarding patient care.Nuclear cardiology encompasses a diverse array of imaging modalities, each offering unique advantages in the evaluation of cardiac function, perfusion, and viability. Perhaps one of the most widely utilized techniques is myocardial perfusion imaging (MPI), which employs single-photon emission computed tomography (SPECT) or positron emission tomography (PET) to assess myocardial blood flow and detect ischemic heart disease. By visualizing the distribution of radiopharmaceuticals within the myocardium, MPI enables the identification of areas of ischemia, infarction, and viable myocardium, thus guiding therapeutic interventions such as revascularization procedures.[1,2].

The significance of nuclear cardiology extends beyond the realm of coronary artery disease (CAD) to encompass various other cardiovascular conditions. For instance, in the evaluation of heart failure, radionuclide ventriculography provides valuable information regarding ventricular function and volumes, aiding in the diagnosis, risk stratification, and management of patients with this complex syndrome. Furthermore, nuclear imaging techniques play a crucial role in the assessment of cardiac sarcoidosis, amyloidosis, and other infiltrative cardiomyopathies, facilitating early detection and guiding targeted therapies.[3,4].

One of the distinguishing features of nuclear cardiology is its ability to assess myocardial viability, a crucial consideration in the management of patients with CAD and left ventricular dysfunction. Through techniques such as myocardial perfusion-metabolism mismatch analysis and fluorodeoxyglucose (FDG) PET imaging, nuclear cardiology enables the differentiation between viable and non-viable myocardium, informing decisions regarding revascularization and predicting long-term outcomes. This capability has profound implications for patient selection and treatment strategies, particularly in the context of ischemic cardiomyopathy and myocardial infarction.Beyond its diagnostic utility, nuclear cardiology plays a vital role in guiding therapeutic interventions and monitoring treatment response. In the realm of interventional cardiology, nuclear imaging techniques such as fractional flow reserve (FFR) derived from SPECT or PET facilitate the assessment of coronary lesions and inform decisions regarding percutaneous coronary intervention (PCI) versus medical therapy. Moreover, nuclear cardiology enables the evaluation of myocardial viability post-revascularization, allowing clinicians to assess the success of interventions and optimize patient outcomes.[5,6].

The evolution of nuclear cardiology has been marked by continuous innovation and technological advancements aimed at enhancing diagnostic accuracy, improving patient safety, and expanding clinical applications. Recent developments such as hybrid imaging systems combining SPECT or PET with computed tomography (CT) or magnetic resonance imaging (MRI) have further augmented the capabilities of nuclear cardiology, enabling the integration of anatomical and functional information in a single imaging session. Additionally, advances in radiotracer development, image processing algorithms, and quantification techniques continue to refine the accuracy and reproducibility of nuclear cardiac imaging studies.[7,8].

Nuclear cardiology, an indispensable component of modern cardiovascular care, encompasses a diverse range of imaging modalities aimed at elucidating the complexities of cardiac physiology and pathology. Through techniques such as myocardial perfusion imaging (MPI), radionuclide ventriculography, and myocardial viability assessment, nuclear cardiology provides clinicians with unparalleled insights into myocardial perfusion, function, and viability, facilitating precise diagnosis, risk stratification, and therapeutic decision-making in patients with various cardiac conditions. Moreover, recent advancements in hybrid imaging systems, radiotracer development, and image processing techniques continue to enhance the accuracy and utility of nuclear cardiac imaging studies, reaffirming its pivotal role in shaping the landscape of cardiovascular medicine.[9,10].


Nuclear cardiology represents a cornerstone of modern cardiovascular care, providing clinicians with invaluable tools for the diagnosis, risk stratification, and management of patients with a wide spectrum of cardiac conditions. Through its ability to assess myocardial perfusion, viability, and function, nuclear imaging techniques offer unique insights into the pathophysiology of cardiovascular diseases, guiding therapeutic decision-making and optimizing patient outcomes. As technology continues to evolve and our understanding of cardiac physiology advances, nuclear cardiology remains at the forefront of innovation, poised to shape the future of cardiovascular medicine
