Which acoustic window is typically used in non-cardiac imaging of the chest?

• A. Subcostal
• B. Intercostal
• C. Substernal
• D. Suprasternal

Answer: (B)

The intercostal acoustic window is commonly utilized in non-cardiac imaging of the chest due to its advantageous positioning. This window allows sonographers to access various structures within the thoracic cavity while avoiding interference from rib shadows. By placing the transducer in the spaces between the ribs, clinicians can visualize organs such as the lungs, pleura, and portions of the mediastinum for assessments of conditions like pleural effusion or lung pathology. Additionally, the intercostal approach minimizes the risk of rib interference, allowing for clearer imaging of the underlying structures. In contrast, other windows such as subcostal, substernal, and suprasternal are generally focused on cardiac assessments or specific anatomical targets, making them less applicable for broader non-cardiac evaluations in the chest region.
