introduction:myocardial 18f-fdg uptake is highly variable in oncologic whole body 18f-fdg pet/ct studies, ranging from quite intense to minimal distribution. intense or heterogeneous myocardial 18f-fdg uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardium or adjacent mediastinal structures. the diet, as...

PURPOSE This study evaluates the prevalence of cardiac metastases in patients with serotonin producing neuroendocrine tumours (NET), examined with 18F-FDOPA PET/CT, and the relationship of these metastases to the presence of carcinoid heart disease (CHD) based on echocardiography. BACKGROUND CHD occurs in patients with serotonin producing NET. The diagnostic method of choice remains echocardi...

Training and competency criteria in cardiac CT were developed to guide practitioners in the process of achieving and maintaining skills in performing and interpreting cardiac CT studies. Appropriate training and eventual certification in cardiac CT angiography may be obtained by adhering to the recommendations for competency as set forth by either the American College of Cardiology Foundation (...

INTRODUCTION Diagnostic tests that use ionizing radiation play a central role in cardiology and their use has grown in recent years, leading to increasing concerns about their potential stochastic effects. The aims of this study were to compare the radiation dose of three diagnostic tests: single photon emission computed tomography (SPECT), invasive coronary angiography (ICA) and cardiac comput...

Cardiac computed tomography (CT) dosimetry makes use of two radiation parameters: a volume CT dose index (CTDI) and a dose length product (DLP). The volume CTDI quantifies the intensity of the radiation used to perform CT examinations, whereas DLP quantifies the amount of radiation used. CTDI metrics can be converted into patient dose metrics by using dose/CTDI conversion factors. In cardiac CT...

AIM Monitoring of cardiotoxicity of conventional and high-dose chemotherapy (HD-CT) with multiple biomarkers of cardiac injury - glycogen phosphorylase BB (GPBB), heart-type fatty acid binding protein (H-FABP), cardiac troponins (cTnT, cTnI), creatine kinase MB (CK-MB mass), myoglobin. METHODS A total of 47 adult acute leukemia patients were studied - 24 patients treated with conventional CT ...

Coronary artery disease (CAD) is a leading cause of mortality and morbidity in most developed countries [1]. CAD is a common and sometimes disabling disorder, although medication therapy, percutaneous coronary intervention and coronary artery bypass grafting have developed recently. Medical doctors need to prevent from developing acute coronary syndrome. The development of non-invasive cardiac ...

Ischemic heart disease is the most common cause of mortality worldwide. Cardiac fibroblasts and myofibroblasts, i.e., the hypersecretory, muscular, and contractile fibroblastic phenotype variant, play an important role in myocardial healing and are responsible for accumulation of collagen in the infarct scar as well as in viable myocardium. Thus, cardiac fibroblasts and myofibroblasts directly ...
