Miravent, SérgioFigueiredo, TeresaCosta Vicente, Bianca Isabel2026-04-292026-04-292025-012405-4690http://hdl.handle.net/10400.1/28813Although lung ultrasound (LUS) has limitations in detecting pulmonary masses, especially small or deep-seated lesions that may be obscured by rib shadows or lung air content, screening ultrasound can still be a valuable tool for identifying these abnormalities in pre-hospital settings. It is especially helpful in situations where advanced tests like detailed blood analyses, biopsies, and the gold standard of computed tomography (CT) scans are not available. This portable, quick, and noninvasive technology can play a key role in detecting serious conditions and ensuring patients are referred to specialized care without unnecessary delays.engLung neoplasmPleural effusionExudates and transudatesMass screeningUltrasonographyjournal article10.1016/j.visj.2025.102228
