Imaging cardiac fat [PDF]

European Heart Journal - Cardiovascular Imaging, 2013
Ectopic fat deposition has been associated with lipotoxicity and derangement in local and systemic metabolism, insulin resistance, cardiac dysfunction, atherosclerosis, local, and systemic inflammation. The mechanisms and potentially detrimental effects of such an accumulation should be fully investigated in order to establish preventive strategies ...

Validation of OSEM algorithm for attenuation correction in cardiac SPECT studies [PDF]

, 2005
Photon attenuation is believed to be one of the major causes of artefacts in cardiac SPECT studies and therefore should be corrected to improve the specificity of cardiac SPECT imaging for the detection of coronary artery disease.

Mid-wall striae fibrosis predicts heart failure admission, composite heart failure events, and life-threatening arrhythmias in dilated cardiomyopathy

Scientific Reports, 2022
Heart failure (HF) admission is a dominant contributor to morbidity and healthcare costs in dilated cardiomyopathy (DCM). Mid-wall striae (MWS) fibrosis by late gadolinium enhancement (LGE) imaging has been associated with elevated arrhythmia risk ...

Temporospatial characterization of ventricular wall motion with real-time cardiac magnetic resonance imaging in health and disease

Scientific Reports, 2022
Cardiac magnetic resonance imaging (MRI) has been largely dependent on retrospective cine for data acquisition. Real-time imaging, although inferior in image quality to retrospective cine, is more informative about motion dynamics.

Left Ventricle Wall Motion Analysis with Real-Time MRI Feature Tracking in Heart Failure Patients: A Pilot Study

Diagnostics, 2022
Volumetric measurements with cardiac magnetic resonance imaging (MRI) are effective for evaluating heart failure (HF) with systolic dysfunction that typically induces a lower ejection fraction (EF) than normal (

Right ventricular insertion site fibrosis in a dilated cardiomyopathy referral population: phenotypic associations and value for the prediction of heart failure admission or death

Journal of Cardiovascular Magnetic Resonance, 2021
Background Dilated cardiomyopathy (DCM) is increasingly recognized as a heterogenous disease with distinct phenotypes on late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging.

Splenic switch-off as a predictor for coronary adenosine response: validation against 13N-ammonia during co-injection myocardial perfusion imaging on a hybrid PET/CMR scanner

Journal of Cardiovascular Magnetic Resonance, 2021
Background Inadequate coronary adenosine response is a potential cause for false negative ischemia testing. Recently, the splenic switch-off (SSO) sign has been identified as a promising tool to ascertain the efficacy of adenosine during vasodilator ...

The Utilization of Cardiac Imaging [PDF]

Circulation, 2006
Cardiac imaging with echocardiography and radionuclide techniques has played an increasingly important role in cardiovascular care over the past decade. Cardiac imaging is currently undergoing rapid evolution. Cardiac magnetic resonance (MR), cardiac computed tomography (CT), and combined positron emission tomography/CT or single photon emission ...

Artificial Intelligence in Cardiac Imaging [PDF]

, 2020
Machine learning (ML), a subset of artificial intelligence, is showing promising results in cardiology, especially in cardiac imaging. ML algorithms are allowing cardiologists to explore new opportunities and make discoveries not seen with conventional ...
