Core tip: Thoracic ultrasound (TUS), with some technical limitations, may provide useful imaging of pleura, lung and heart disease. The field of application of TUS are pleural effusion, pneumothorax, and lung consolidation. Paediatric and newborn disease are suitable for TUS investigation aimed at the detection of congenital or acquired chest disease avoiding or limiting radiological exposure. TUS improves the effectiveness of medical practice in resource-limited settings, in small point-of-care facilities, in hostile environment and in poorer countries. Monitoring of patients is possible, depending on disease and context, not asking to the procedure more than it can give.
