Deep Learning Techniques for Automatic MRI Cardiac Multi-Structures Segmentation and Diagnosis: Is the Problem Solved?
(2018-11)Delineation of the left ventricular cavity, myocardium, and right ventricle from cardiac magnetic resonance images (multi-slice 2-D cine MRI) is a common clinical task to establish diagnosis. The automation of the corresponding ... -
Cardiovascular magnetic resonance imaging for amyloidosis: The state-of-the-art.
(2019-02)Amyloidosis results from insoluble precursor proteins being deposited in the extracellular compartment. The prognosis of the disease is predominantly determined by cardiac involvement due to amyloid accumulation that ... -
Lifestyle advice and interventions for cardiovascular risk reduction: A systematic review of guidelines.
(2018-07-15)BACKGROUND: Lifestyle factors are important in preventing cardiovascular disease (CVD) development. We aimed to systematically review guidelines on primary prevention of CVD and their recommendations on lifestyle advice ... -
The impact of menopausal hormone therapy (MHT) on cardiac structure and function: Insights from the UK Biobank imaging enhancement study.
(2018)BACKGROUND: The effect of menopausal hormone therapy (MHT)-previously known as hormone replacement therapy-on cardiovascular health remains unclear and controversial. This cross-sectional study examined the impact of MHT ... -
Prospective association between handgrip strength and cardiac structure and function in UK adults.
(2018)BACKGROUND: Handgrip strength, a measure of muscular fitness, is associated with cardiovascular (CV) events and CV mortality but its association with cardiac structure and function is unknown. The goal of this study was ... -
Diagnosing coronary artery disease after a positive coronary computed tomography angiography: the Dan-NICAD open label, parallel, head to head, randomized controlled diagnostic accuracy trial of cardiovascular magnetic resonance and myocardial perfusion scintigraphy.
(2018-04-01)Aims: Perfusion scans after coronary computed tomography angiography (CCTA) in patients with suspected coronary artery disease (CAD) may reduce unnecessary invasive coronary angiographies (ICAs). However, the diagnostic ... -
Protocol and quality assurance for carotid imaging in 100,000 participants of UK Biobank: development and assessment.
(2017-11)Background Ultrasound imaging is able to quantify carotid arterial wall structure for the assessment of cerebral and cardiovascular disease risks. We describe a protocol and quality assurance process to enable carotid ... -
Ineffective and prolonged apical contraction is associated with chest pain and ischaemia in apical hypertrophic cardiomyopathy.
(2018-01-15)OBJECTIVES: To investigate the hypothesis that persistence of apical contraction into diastole is linked to reduced myocardial perfusion and chest pain. BACKGROUND: Apical hypertrophic cardiomyopathy (HCM) is defined by ... -
Diagnosis and Prognosis in Sudden Cardiac Arrest Survivors Without Coronary Artery Disease: Utility of a Clinical Approach Using Cardiac Magnetic Resonance Imaging.
(2017-12)BACKGROUND: Determining the pathogenesis of sudden cardiac arrest or periarrest without significant coronary artery disease is crucial for management and prognosis. Cardiovascular magnetic resonance (CMR) can detect ... -
Functional assessment of coronary artery disease by cardiac computed tomography.
(2017-09)INTRODUCTION: Rapid technological advances in computed tomography (CT) have allowed CT coronary angiography (CTCA) to be delivered at low radiation dose and high diagnostic accuracy. Due to its high negative predictive ... -
Myocardial deformation assessment using cardiovascular magnetic resonance-feature tracking technique.
(2017-12)BACKGROUND: Cardiovascular magnetic resonance (CMR) imaging is an important modality that allows the assessment of regional myocardial function by measuring myocardial deformation parameters, such as strain and strain rate ...
