A pleural effusion ultrasound is a diagnostic imaging technique used to assess and characterize pleural effusions, a condition in which fluid accumulates in the pleural space between the lung and the chest wall.

This non-invasive procedure involves using an ultrasound machine and a transducer to create real-time images of the thoracic region. By examining the pleural surfaces and fluid distribution, ultrasound can identify and classify different types of pleural effusions, such as transudative or exudative effusions. It can also help determine the extent and location of the fluid accumulation and guide procedures like thoracentesis for therapeutic or diagnostic purposes. Pleural effusion ultrasound is a valuable tool in the evaluation of patients with respiratory symptoms, allowing healthcare professionals to accurately diagnose and manage pleural effusions more effectively.
