Detecting Pulmonary Embolism from Computed Tomography Using Convolutional Neural Network [PDF]

arXiv, 2022
The clinical symptoms of pulmonary embolism (PE) are very diverse and non-specific, which makes it difficult to diagnose. In addition, pulmonary embolism has multiple triggers and is one of the major causes of vascular death. Therefore, if it can be detected and treated quickly, it can significantly reduce the risk of death in hospitalized patients. In

Transcatheter valve repair of tricuspid regurgitation with the PASCAL system: TriCLASP study 30‐day results

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1291-1299, December 1, 2022., 2022
Abstract Background Severe tricuspid regurgitation (TR) is independently associated with increased morbidity and mortality. Percutaneous transcatheter approaches may offer an alternative for patients not amenable to surgery. Methods TriCLASP is a prospective, single‐arm, multicenter European post‐market clinical follow‐up study (NCT04614402) to ...

Topology Repairing of Disconnected Pulmonary Airways and Vessels: Baselines and a Dataset [PDF]

arXiv, 2023
Accurate segmentation of pulmonary airways and vessels is crucial for the diagnosis and treatment of pulmonary diseases. However, current deep learning approaches suffer from disconnectivity issues that hinder their clinical usefulness. To address this challenge, we propose a post-processing approach that leverages a data-driven method to repair the ...

Symmetry-Enhanced Attention Network for Acute Ischemic Infarct Segmentation with Non-Contrast CT Images [PDF]

, 2021
Quantitative estimation of the acute ischemic infarct is crucial to improve neurological outcomes of the patients with stroke symptoms. Since the density of lesions is subtle and can be confounded by normal physiologic changes, anatomical asymmetry provides useful information to differentiate the ischemic and healthy brain tissue.

Coronary angiography of the ex‐situ beating donor heart in a portable organ care system

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1252-1260, December 1, 2022., 2022
Abstract Objectives To determine safety and feasibility of ex‐situ coronary angiography. Background To cater for the perpetually growing demand for heart donors, interest in donation following circulatory death (DCD) has been rekindled. Further pursuit of donor pool expansion has led to eligibility extension to “marginal” donors who are at higher risk ...

Pulmonary Fissure Segmentation in CT Images Based on ODoS Filter and Shape Features [PDF]

arXiv, 2022
Priori knowledge of pulmonary anatomy plays a vital role in diagnosis of lung diseases. In CT images, pulmonary fissure segmentation is a formidable mission due to various of factors. To address the challenge, an useful approach based on ODoS filter and shape features is presented for pulmonary fissure segmentation.
