Implementable Deep Learning for Multi‐sequence Proton MRI Lung Segmentation: A Multi‐center, Multi‐vendor, and Multi‐disease Study

Joshua R. Astley, Alberto M. Biancardi, Paul J. C. Hughes, Helen Marshall, more

Journal of Magnetic Resonance Imaging > 58 > 4 > 1030 - 1044

Background Recently, deep learning via convolutional neural networks (CNNs) has largely superseded conventional methods for proton (¹H)‐MRI lung segmentation. However, previous deep learning studies have utilized single‐center data and limited acquisition parameters. Purpose Develop a generalizable CNN for lung segmentation in ¹H‐MRI, robust to pathology, acquisition protocol, vendor, and center...

The Interfield Strength Agreement of Left Ventricular Strain Measurements at 1.5 T and 3 T Using Cardiac MRI Feature Tracking

Sarah L. Ayton, Aseel Alfuhied, Gaurav S. Gulsin, Kelly S. Parke, more

Journal of Magnetic Resonance Imaging > 57 > 4 > 1250 - 1261

Background Left ventricular (LV) strain measurements can be derived using cardiac MRI from routinely acquired balanced steady‐state free precession (bSSFP) cine images. Purpose To compare the interfield strength agreement of global systolic strain, peak strain rates and artificial intelligence (AI) landmark‐based global longitudinal shortening at 1.5 T and 3 T. Study Type Prospective. Subjects...

Triple-gated motion and blood pool clearance corrections improve reproducibility of coronary ¹⁸F-NaF PET

Martin Lyngby Lassen, Jacek Kwiecinski, Damini Dey, Sebastien Cadet, more

European Journal of Nuclear Medicine and Molecular Imaging > 2019 > 46 > 12 > 2610-2620

Purpose To improve the test–retest reproducibility of coronary plaque ¹⁸F-sodium fluoride (¹⁸F-NaF) positron emission tomography (PET) uptake measurements. Methods We recruited 20 patients with coronary artery disease who underwent repeated hybrid PET/CT angiography (CTA) imaging within 3 weeks. All patients had 30-min PET acquisition and CTA during a single imaging session. Five PET image-sets...

The Updated NICE Guidelines: Cardiac CT as the First-Line Test for Coronary Artery Disease

Alastair J. Moss, Michelle C. Williams, David E. Newby, Edward D. Nicol

Current Cardiovascular Imaging Reports > 2017 > 10 > 5 > 1-7

Purpose of Review Cost-effective care pathways are integral to delivering sustainable healthcare programmes. Due to the overestimation of coronary artery disease using traditional risk tables, non-invasive testing has been utilised to improve risk stratification and initiate appropriate management to reduce the dependence on invasive investigations. In line with recent technological improvements,...

Computed Tomography and Cardiac Magnetic Resonance in Ischemic Heart Disease

Marc R. Dweck, Michelle C. Williams, Alastair J. Moss, David E. Newby, more

Journal of the American College of Cardiology > 2016 > 68 > 20 > 2201-2216

Ischemic heart disease is a complex disease process caused by the development of coronary atherosclerosis, with downstream effects on the left ventricular myocardium. It is characterized by a long preclinical phase, abrupt development of myocardial infarction, and more chronic disease states such as stable angina and ischemic cardiomyopathy. Recent advances in computed tomography (CT) and cardiac...
