- W4246194670 abstract "Abstract The aim of cardiac imaging is to contribute to the diagnosis of cardiac and vascular diseases by detecting early signs of abnormal activity, and to contribute to therapy follow‐up. Cardiac imaging attempts to detect global or local abnormalities in morphology, function, perfusion, and metabolism of the heart and vessels, including the evaluation of myocardial viability and artery plaques. The main imaging modalities are presented here. X‐ray angiography is useful for assessing heart and vessel anatomy, although it is an invasive modality requiring catheterization. Echocardiography is a widespread, cheap, and non‐invasive modality that can analyze cardiac anatomy, tissue and blood motion, and perfusion. Traditionally, nuclear imaging with thallium or technetium has been used to detect myocardial perfusion defects. Recently, molecular imaging, using positron emission tomography, has been proposed to identify molecular processes like angiogenesis or apoptosis. Cardiac magnetic resonance imaging is attracting increasing interest as it can now produce high‐quality images with good spatial resolution. Apart from evaluating anatomy, it also allows assessment of tissue and blood motion, perfusion, and myocardial viability. Finally, ultrafast computed tomography may also produce high‐resolution images of the heart and great vessels, showing and characterizing their function and assessing plaques in coronary arteries. As will be seen, currently available imaging modalities are complementary, showing different characteristics of cardiovascular structures and helping to achieve an accurate and early diagnosis of cardiovascular diseases." @default.
