Mini-COVIDNet: Efficient Lightweight Deep Neural Network for Ultrasound Based Point-of-Care Detection of COVID-19
2021
Lung ultrasound (US) imaging has the potential to be an effective point-of-care test for detection of COVID-19, due to its ease of operation with minimal personal protection equipment along with easy disinfection. The current state-of-the-art deep learning models for detection of COVID-19 are heavy models that may not be easy to deploy in commonly utilized mobile platforms in point-of-care testing. In this work, we develop a lightweight mobile friendly efficient deep learning model for detection of COVID-19 using lung US images. Three different classes including COVID-19, pneumonia, and healthy were included in this task. The developed network, named as Mini-COVIDNet, was bench-marked with …
B-Lines for the assessment of extravascular lung water: Just focused or semi-quantitative?
2020
BACKGROUND B-lines as typical artefacts of lung ultrasound are considered as surrogate measurement for extravascular lung water. However, B-lines develop in the sub-pleural space and do not allow assessment of the whole lung. Here, we present data from the first observational multi-centre study focusing on the correlation between a B-lines score and extravascular lung water in critically ill patients suffering from a variety of diseases. PATIENTS AND METHODS In 184 adult patients, 443 measurements were obtained. B-lines were counted and expressed in a score which was compared to extravascular lung water, measured by single-indicator transpulmonary thermodilution. Appropriate correlation coe…
Thoracic ultrasound: Potential new tool for physiotherapists in respiratory management. A narrative review
2016
International audience; The use of diagnostic ultrasound by physiotherapists is not a new concept; it is frequently performed in musculoskeletal physiotherapy. Physiotherapists currently lack accurate, reliable, sensitive, and valid measurements for the assessment of the indications and effectiveness of chest physiotherapy. Thoracic ultrasound may be a promising tool for the physiotherapist and could be routinely performed at patients' bedsides to provide real-time and accurate information on the status of pleura, lungs, and diaphragm; this would allow for assessment of lung aeration from interstitial syndrome to lung consolidation with much better accuracy than chest x-rays or auscultation…
Quantitative Lung Ultrasound: Technical Aspects and Clinical Applications.
2021
Lung ultrasound is increasingly used in emergency departments, medical wards, and critical care units—adult, pediatric, and neonatal. In vitro and in vivo studies show that the number and type of artifacts visualized change with lung density. This has led to the idea of a quantitative lung ultrasound approach, opening up new prospects for use not only as a diagnostic but also as a monitoring tool. Consequently, the multiple scoring systems proposed in the last few years have different technical approaches and specific clinical indications, adaptable for more or less time-dependent patients. However, multiple scoring systems may generate confusion among physicians aiming at introducing lung …
PROTOCOLLO ECOGRAFICO DEL PAZIENTE CON SCOMPENSO CARDIACO: RISULTATI AGGIORNATI DELLO STUDIO MULTICENTRICO SIUMB ABCDE 2018-2022
2019
Lo scompenso cardiaco è una sindrome clinica caratterizzata da specifici segni e sintomi causati da anomalie cardiache di tipo strutturale e/o funzionale. La prevalenza dello scompenso cardiaco è di circa 1-2% nella popolazione adulta dei paesi industrializzati, aumenta fin oltre il 10% oltre i 70 anni ed è la maggiore causa di ospedalizzazione oltre che di disabilità. L’approccio ecografico al paziente con scompenso cardiaco è ad oggi pratica comune, sia per la valutazione della funzionalità cardiaca, sia per il monitoraggio dello stato di volemia che per la quantificazione del liquido interstiziale. Dal 2018 è in corso uno studio multicentrico italiano (“ABCDE”) patrocinato dalla SIUMB ch…
Quality control of B-lines analysis in stress Echo 2020
2018
Background The effectiveness trial “Stress echo (SE) 2020” evaluates novel applications of SE in and beyond coronary artery disease. The core protocol also includes 4-site simplified scan of B-lines by lung ultrasound, useful to assess pulmonary congestion. Purpose To provide web-based upstream quality control and harmonization of B-lines reading criteria. Methods 60 readers (all previously accredited for regional wall motion, 53 B-lines naive) from 52 centers of 16 countries of SE 2020 network read a set of 20 lung ultrasound video-clips selected by the Pisa lab serving as reference standard, after taking an obligatory web-based learning 2-h module ( http://se2020.altervista.org ). Each te…
Lung ultrasound in outpatients with heart failure: the wet‐to‐dry HF study
2021
The Nancy team is supported by the RHU Fight-HF, a public grant overseen by the French National Research Agency (ANR) as part of the second 'Investissements d'Avenir' programme (reference: ANR-15-RHUS-0004), by the French PIA project 'Lorraine Université d'Excellence' (reference: ANR-15-IDEX-04-LUE), the ANR FOCUS-MR (reference: ANR-15-CE14-0032-01), ERA-CVD EXPERT (reference: ANR-16-ECVD-0002-02), the Contrat de Plan Etat Lorraine IT2MP, and FEDER Lorraine. Aims: In ambulatory patients with chronic heart failure (HF), congestion and decongestion assessment may be challenging. The aim of this study is to assess the value of lung ultrasound (LUS) in outpatients with HF in characterizing deco…
Lung ultrasound in internal medicine efficiently drives the management of patients with heart failure and speeds up the discharge time
2017
Lung ultrasound (LUS) is a valid tool for the assessment of heart failure (HF) through the quantification of the B-lines. This study in HF patients aims to evaluate if LUS: (1) can accelerate the discharge time; (2) can efficiently drive diuretic therapy dosage; and (3) may have better performance compared to the amino-terminal portion of B type natriuretic peptide (NT-proBNP) levels in monitoring HF recovery. A consecutive sample of 120 HF patients was admitted from the Emergency Department (ED) to the Internal Medicine Department (Verona University Hospital). The Chest X-ray (CXR) group underwent standard CXR examination on admission and discharge. The LUS group underwent LUS on admission…
Echocardiographic and lung ultrasound characteristics in ambulatory patients with dyspnea or prior heart failure.
2013
Purpose Lung ultrasound (LUS) represents a novel, noninvasive method in the assessment of extravascular lung water. We investigated the utility of LUS in ambulatory subjects with dyspnea or prior heart failure (HF). Methods We studied 81 ambulatory subjects with HF history or dyspnea who underwent transthoracic echocardiography (TTE) with LUS of 8 zones. Subjects with heart transplantation or pulmonary conditions known to interfere with LUS were excluded. A reviewer blinded to the clinical data performed echocardiographic measurements and quantified B-lines (reverberation artifacts arising from the pleural line). Results Of 81 subjects, 74 (91%) (median age 66 years, 39% men, median left ve…
