The role of thoracic ultrasonography in the diagnosis of anterior mediastinal lesions
Ultrasonography (US) is an imaging modality based on the reflection of sound waves directed at tissues with the aid of a transducer. Since different tissues reflect sound waves at various frequencies, images also demonstrate variations. Soft tissues transmit sound waves better, they are hypoechoic, and appear as dark image. Pulmonary parenchyma contains air, which dissipates ultrasound energy, so it is not well visualized on US.[1]
