Automated quantification and evaluation of motion artifact on coronary CT angiography images [PDF]

, 2018
Purpose This study developed and validated a Motion Artifact Quantification algorithm to automatically quantify the severity of motion artifacts on coronary computed tomography angiography (CCTA) images. The algorithm was then used to develop a Motion IQ

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Impact of Ceiling Suspended Shield Size on Primary Operator Radiation Dose During Coronary Angiography and Intervention

Journal of Medical Radiation Sciences, EarlyView.
Reducing radiation exposure to staff performing coronary angiography and intervention is an occupational health and safety priority for hospitals. We demonstrate that a larger lead acrylic shield, with lead rubber pleats on the lower edge will reduce radiation exposure to the cardiologist performing the procedure by approximately 40%. We recommend that

Coronary Artery Centerline Extraction in Cardiac CT Angiography Using a CNN-Based Orientation Classifier

, 2018
Coronary artery centerline extraction in cardiac CT angiography (CCTA) images is a prerequisite for evaluation of stenoses and atherosclerotic plaque. We propose an algorithm that extracts coronary artery centerlines in CCTA using a convolutional neural ...

Atypical Wounds in Chronic Graft‐Versus‐Host Disease and Peripheral Arterial Disease Caused by Tyrosine Kinase Inhibitors

JEADV Clinical Practice, EarlyView.
ABSTRACT The term “atypical wounds” primarily refers to lesions with immunological or cancerous etiologies. However, these wounds can also be drug‐induced. We report about a 32‐year‐old man with a 6‐year history of chronic myelogenous leukemia (CML) and chronic graft‐versus‐host disease (cGvHD) following an HLA‐compatible allogeneic stem cell ...

TET3‐Mediated m5C Modification of CCAT2 Accelerates Cardiac Microvascular Endothelial Cell Damage in Acute Coronary Syndrome

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Acute coronary syndrome (ACS) is a clinical syndrome involving myocardial ischemia. This study aimed to elucidate the mechanism of TET3 in ACS‐induced CMEC damage, thereby identifying a new target for ACS treatment. The expression of TET3 in ACS patients and healthy subjects was analyzed.

Impact of CYP2C19 Genotype Variants on PCSK9 Inhibitor Efficacy in Lipid‐Lowering Among Patients With Symptomatic Intracranial Atherosclerotic Stenosis

Lipids, EarlyView.
ABSTRACT Ischemic stroke is frequently associated with symptomatic intracranial atherosclerotic stenosis (sICAS), is a leading cause of global disability and mortality. Current guidelines recommend dual antiplatelet and intensive statin therapies. Proprotein convertase subtilisin 9/kexin type 9 (PCSK9) inhibitors have emerged as a potent lipid‐lowering
