Respiratory and cardiac motion artefacts degrade image quality in positron emission tomography (PET) imaging and may significantly affect the qualitative and quantitative evaluation of images. At worst, misguided interpretation may lead to wrong diagnosis and inadequate or unnecessary treatment. The aim of this thesis was to study the feasibility of the bioimpedancebased measurement technique f...

The capability of radionuclide imaging to detect experimental aortic valve infective endocarditis was assessed with indium-111 ("'In)-labeled blood cells. Sequential cardiac imaging and tissue distribution studies were obtained in 17 rabbits with infective endocarditis after administration of "..In-platelets and in five after "'In-polymorphonuclear leukocytes. Forty-eight to 72 hours after plat...

conclusions according to our multimodality imaging approach, hypertrophic cardiomyopathy was the most probable diagnosis. case presentation we describe a 73-year-old woman referred to us for consultation because of a giant negative t wave on her electrocardiography. echocardiography revealed diffuse severe hypertrophy associated with hypertrophied anterolateral papillary muscles with a bifid he...

echocardiography is a non-invasive diagnostic technique which provides information regarding cardiac function and hemodynamics. it is the most frequently used cardiovascular diagnostic test after electrocardiography and chest x-ray. however, in a patient with acute chest pain, transthoracic echocardiography is essential both for diagnosing acute coronary syndrome, zeroing on the evaluation of v...

Patients with left-sided breast cancer are at risk of cardiac toxicity because of cardiac irradiation during radiotherapy with the conventional 3-dimensional conformal radiotherapy technique. In addition, many patients may receive chemotherapy prior to radiation, which may damage the myocardium and may increase the potential for late cardiac complications. New radiotherapy techniques such as in...

BACKGROUND Obesity is a major health problem in the Western world. Among obese subjects cardiac pathology is common, but conventional noninvasive imaging modalities are often suboptimal for detailed evaluation of cardiac structure and function. We investigated whether cardiovascular magnetic resonance imaging (CMR) can better characterize possible cardiac abnormalities associated with obesity, ...

Cardiac magnetic resonance (CMR) diffusion tensor imaging (DTI) is a promising technique capable of probing the myocardial microstructure by assessing the myofiber orientation. New technical developments in CMR DTI in recent years have allowed the clinical application of this powerful imaging technique. CMR DTI has been used to study myocardial infarction and hypertrophic cardiomyopathy in pati...

Cardiac deformation imaging is being used more and more routinely in resting echocardiography. The technique can also be applied to stress studies, and may provide additional information to that obtained by standard analysis alone. This review explores its present role, limitations, and potential uses. Although currently not widely used in stress studies, deformation imaging has the capability ...

An accurate quantitative and qualitative assessment of cardiac function is critical for clinical diagnosis, risk stratification, management and prognosis in patients with suspected or documented heart disease. Magnetic resonance, owing to its excellent temporal and spatial resolution, is currently considered a reference standard in the assessment of cardiac function. Multidetector-row computed ...

In 2010, the ASCI provided recommendations for cardiac CT and MRI. This document reflects an updating of the prior 2010 ASCI appropriate use criteria (AUC). In 2016, the ASCI formed a new working group for revision of AUC on noninvasive cardiac imaging. A major change that we made in this document is the rating of various noninvasive tests (exercise electrocardiogram, echocardiography, positron...
