Spotlight on nerves: Portable multispectral optoacoustic imaging of peripheral nerve vascularization and morphology [PDF]

arXiv, 2022
Various morphological and functional parameters of peripheral nerves and their vascular supply are indicative of pathological changes due to injury or disease. Based on recent improvements in optoacoustic image quality, we explore the ability of multispectral optoacoustic tomography, in tandem with ultrasound imaging (OPUS), to investigate the vascular

TransONet: Automatic Segmentation of Vasculature in Computed Tomographic Angiograms Using Deep Learning [PDF]

arXiv, 2023
Pathological alterations in the human vascular system underlie many chronic diseases, such as atherosclerosis and aneurysms. However, manually analyzing diagnostic images of the vascular system, such as computed tomographic angiograms (CTAs) is a time-consuming and tedious process.

A Probabilistic Neural Twin for Treatment Planning in Peripheral Pulmonary Artery Stenosis [PDF]

arXiv, 2023
The substantial computational cost of high-fidelity models in numerical hemodynamics has, so far, relegated their use mainly to offline treatment planning. New breakthroughs in data-driven architectures and optimization techniques for fast surrogate modeling provide an exciting opportunity to overcome these limitations, enabling the use of such ...

Transfer Learning for Retinal Vascular Disease Detection: A Pilot Study with Diabetic Retinopathy and Retinopathy of Prematurity [PDF]

arXiv, 2022
Retinal vascular diseases affect the well-being of human body and sometimes provide vital signs of otherwise undetected bodily damage. Recently, deep learning techniques have been successfully applied for detection of diabetic retinopathy (DR). The main obstacle of applying deep learning techniques to detect most other retinal vascular diseases is the ...

Extraction of Vascular Wall in Carotid Ultrasound via a Novel Boundary-Delineation Network [PDF]

arXiv, 2022
Ultrasound imaging plays an important role in the diagnosis of vascular lesions. Accurate segmentation of the vascular wall is important for the prevention, diagnosis and treatment of vascular diseases. However, existing methods have inaccurate localization of the vascular wall boundary.

Vascular Teams in Peripheral Vascular Disease

Journal of the American College of Cardiology, 2019
Peripheral vascular disease affects millions of individuals worldwide, and results in significant morbidity and mortality. The complex nature of the disease, the presence of multiple comorbidities, and the existence of a wide variety of therapeutic options suggests that a multidisciplinary approach to treatment has the potential to improve care of ...

Sensitivity analysis and uncertainty quantification of 1D models of the pulmonary circulation [PDF]

, 2018
This study combines a one-dimensional (1D) model with micro-CT imaging and hemodynamic data to quantify uncertainty of flow and pressure predictions in the pulmonary arteries in a control and hypoxia induced hypertensive mouse. We use local and global sensitivity and correlation analysis to determine parameters that can be inferred from the model and ...

The hypotensive effect of activated apelin receptor is correlated with \b{eta}-arrestin recruitment [PDF]

Elie Besserer-Offroy, et al. Pharmacol Res, Epub 9 March 2018, 2018
The apelinergic system is an important player in the regulation of both vascular tone and cardiovascular function, making this physiological system an attractive target for drug development for hypertension, heart failure and ischemic heart disease.
