Association of plasma metabolites and cardiac mitochondrial function with heart failure progression

ESC Heart Failure, EarlyView.
Abstract Aims Plasma metabolites are prognostic in heart failure with reduced ejection fraction (HFrEF), with citric acid cycle metabolites linked to ejection fraction (EF) changes. We investigated these mechanisms in a canine chronic HFrEF model. We tested associations between changes in plasma metabolites, left ventricular (LV) end‐diastolic volume ...

TiAVox: Time-aware Attenuation Voxels for Sparse-view 4D DSA Reconstruction [PDF]

arXiv, 2023
Four-dimensional Digital Subtraction Angiography (4D DSA) plays a critical role in the diagnosis of many medical diseases, such as Arteriovenous Malformations (AVM) and Arteriovenous Fistulas (AVF). Despite its significant application value, the reconstruction of 4D DSA demands numerous views to effectively model the intricate vessels and radiocontrast

Optic Disc Pallor in Parkinson's Disease: A UK Biobank Study

Movement Disorders, EarlyView.
Abstract Background Recent studies have suggested that retinal changes measured with optical coherence tomography are detectable in early Parkinson's disease (PD), highlighting the potential of ophthalmic biomarkers for diagnosis and monitoring. Objective We set out to investigate the relationship between optic disc pallor measured in fundoscopy images

Technique selection and technical developments for 2D dual‐energy subtraction angiography on an interventional C‐arm

Medical Physics, EarlyView.
Abstract Background Dual‐energy (DE) x‐ray image acquisition has the potential to provide material‐specific angiographic images in the interventional suite. This approach can be implemented with novel detector technologies, such as dual‐layer and photon‐counting detectors.

autoTICI: Automatic Brain Tissue Reperfusion Scoring on 2D DSA Images of Acute Ischemic Stroke Patients [PDF]

, 2020
The Thrombolysis in Cerebral Infarction (TICI) score is an important metric for reperfusion therapy assessment in acute ischemic stroke. It is commonly used as a technical outcome measure after endovascular treatment (EVT). Existing TICI scores are defined in coarse ordinal grades based on visual inspection, leading to inter- and intra-observer ...
