The impact of the microvascular resistance on the measures of stenosis severity [PDF]

arXiv
The relationship between measures of stenosis and microvascular resistance is of importance due to medical decisions being based on these values. This research investigates the impact of varying microvascular resistance on fractional flow reserve (FFR) and hyperaemic stenosis resistance (hSR).

Technical Report: Modelling Multiple Cell Types with Partial Differential Equations [PDF]

arXiv, 2015
Partial differential equations are a convenient way to describe reaction- advection-diffusion processes of signalling models. If only one cell type is present, and tissue dynamics can be neglected, the equations can be solved directly. However, in case of multiple cell types it is not always straight forward to integrate a continuous description of the

A Difficult Recurrent Hypertrophic Pyloric Stenosis

Journal of Neonatal Surgery, 2017
A 20-day-old girl presented with increasing projectile vomiting over a period of one week and progressive weight loss. The diagnosis of hypertrophic pyloric stenosis (HPS) was made by sonography (Length of pyloric channel: 22 mm; muscle thickness: 5 mm).

Maternal factors in the origin of infantile hypertrophic pyloric stenosis: A population‐based case‐control study

Congenital Anomalies, 2016
In most patients affected by isolated infantile hypertrophic pyloric stenosis (IHPS) the etiology is largely unknown. Thus, the aim of this study was to estimate possible maternal risk factors in the origin of IHPS.

Computational Assessment of Hemodynamics in Asymmetric-type Lesion of Idealized Coronary Stenoses [PDF]

arXiv
Coronary artery stenosis, characterized by the narrowing of the lumen, significantly affects blood flow and contributes to the progression of cardiovascular diseases. This study investigates the hemodynamics of coronary artery models with varying stenosis configurations, all maintaining an 80% lumen reduction, to determine how differences in morphology

Automated Characterization of Stenosis in Invasive Coronary Angiography Images with Convolutional Neural Networks [PDF]

arXiv, 2018
The determination of a coronary stenosis and its severity in current clinical workflow is typically accomplished manually via physician visual assessment (PVA) during invasive coronary angiography. While PVA has shown large inter-rater variability, the more reliable and accurate alternative of Quantitative Coronary Angiography (QCA) is challenging to ...

Minimally invasive approach to non-communicating pyloric duplication

Journal of Pediatric Surgery Case Reports, 2018
Pyloric duplication is a rare subset of alimentary tract duplications that can present in a manner almost identical to hypertrophic pyloric stenosis.

M-SCAN: A Multistage Framework for Lumbar Spinal Canal Stenosis Grading Using Multi-View Cross Attention [PDF]

arXiv
The increasing prevalence of lumbar spinal canal stenosis has resulted in a surge of MRI (Magnetic Resonance Imaging), leading to labor-intensive interpretation and significant inter-reader variability, even among expert radiologists. This paper introduces a novel and efficient deep-learning framework that fully automates the grading of lumbar spinal ...
