Core Tip

Core tip: Ultrasonography provides a simple and non-invasive means of assessing diaphragmatic function. This article describes the different methods used to measure diaphragmatic excursion and thickness and detect diaphragmatic paralysis or dysfunction. Furthermore, the paper presents the various pathological conditions for which diaphragmatic ultrasound may be useful such as circumstances at high risk of phrenic nerve injury and diseases affecting diaphragmatic function. The development of methods such as speckle tracking imaging and ultrasound shear wave elastography should provide more detailed information for better assessment of diaphragmatic function.
