Quantitative approaches to improve lung ultrasound (LUS) vertical artifacts (VA) interpretation using total signal intensity (ITOT) are not widely available for clinical practice. In this study, we aimed to i) develop a mathematical algorithm to extract ITOT as a post-hoc LUS analysis and ii) confirm ITOT utility by conducting laboratory VA research using an in vitro model with different acoustic channels. The ...
Objective: The aim of the work described here was to analyze the relationship between the change in ultrasound (US) settings and the vertical artifacts' number, visual rating, and signal intensity METHODS: An in vitro phantom consisting of a damp sponge and gelatin mix was created to simulate vertical artifacts. Furthermore, several US parameters were changed sequentially (i.e., frequency, dynamic range, line d...
Introdução: A ultrassonografia transcraniana (UT) surge como uma técnica útil no diagnóstico diferencial de doenças do movimento, nomeadamente em síndromes parkinsónicos e na clarificação dos mecanismos fisiopatológicos subjacentes. Objetivo: Descrever a utilidade da UT no diagnóstico diferencial em síndromes parkinsónicos. Metodologia: Realizou-se pesquisa nas bases de dados Pubmed e Scopus, filtrando artigos ...
