Computational strategy for the segmentation of the aortic annulus in cardiac computed tomography images
(IOP Publishing, 2019)
The purpose of this research is to segment the aortic annulus, present in cardiac
computed tomography images, from a computational strategy generated using global similarity
enhancement, vector least squares support ...
Dual energy cardiac computed tomography
(Edizioni Minerva Medica, 2017-06)
Conventional single energy CT suffers from technical limitations related to the polychromatic nature of X-rays. Dual energy cardiac CT (DE CT) shows promise to attenuate and even overcome some of these limitations, and ...
Left ventricular thrombus attenuation characterization in cardiac computed tomography angiography
(ELSEVIER SCIENCE INCNEW YORK, 2012)
BACKGROUND: Because of their similar visual appearance, differentiation of left ventricular thrombotic material and myocardial wall can be difficult in contrast-enhanced coronary computed tomography (CT) angiography. ...
Right coronary artery fistula to the coronary sinus and right atrium associated with giant right coronary enlargement detected by transthoracic echocardiography
(OXFORD UNIV PRESS, 2011)
We present the case of a 54-year-old female with a previous history of lung fibrosis secondary to methotrexate used for rheumatoid arthritis who was referred to cardiology evaluation due to precordial pain. Echocardiography ...
Description and use of Three-Dimensional Numerical Phantoms of Cardiac Computed Tomography Images
(MDPI, 2022)
The World Health Organization indicates the top cause of death is heart disease. These diseases can be detected using several imaging modalities, especially cardiac computed tomography (CT), whose images have imperfections ...
Isotropic versus anisotropic techniques in cardiac computed tomography images processing
(IOP Publishing, 2019)
The objective of the work is to compare the performance of two filters, one isotropic
and another one of anisotropic diffusion based on gradient. To do this, experiments are carried
out to establish which of the filters ...
Complete cardiac and bronchial avulsion in a dog: Post-mortem computed tomography and forensic necropsy analysis
(Elsevier B.V., 2017-03-01)
The aim of this case report was to describe non-contrast tomography findings of a cardiovascular trauma followed by a forensic necropsy in a dog. A female dog was struck by a vehicle, suffered a sudden death and was sent ...
Sternal torsion in pectus excavatum is related to cardiac compression and chest malformation indexes
(W B Saunders Co-Elsevier Inc, 2020-04)
Background/purpose: The role of sternal torsion (ST) in patients with pectus excavatum (PEX) is unknown. We evaluated the relationship between ST and both chest malformation and cardiac compression (CC) indexes. Methods: ...
Preoperative chest computed tomography screening for coronavirus disease 2019 in asymptomatic patients undergoing cardiac surgery
Due to the outbreak of Severe Acute Respiratory Syndrome coronavirus
(SARS-Cov-2), an efficient COVID-19 screening strategy is required for
patients undergoing cardiac surgery. The objective of this prospective
observational ...
