Current and Emerging Radiotracers in Molecular Cardiovascular Imaging

Cardiovascular imaging has rapidly advanced over the past decades. Traditional imaging techniques like echocardiography, computed tomography (CT), and cardiovascular magnetic resonance (CMR) are essential for assessing the structural and functional aspects of the cardiovascular system but often fall short in providing direct insights into disease activity. This gap is increasingly being bridged by molecular nuclear imaging techniques, including positron emission tomography (PET) and single-photon emission computed tomography (SPECT), which enable the visualization of disease processes at the molecular and cellular levels. This review highlights the role of cardiovascular molecular imaging, emphasizing its current and potential applications in diagnosing and managing cardiovascular disease. With advancements in PET scanners, novel radiotracers, and sophisticated imaging software, molecular imaging is set to play an essential role in precision medicine by enhancing our understanding of disease mechanisms, accelerating the development of targeted therapies, and facilitating personalized patient care.
