Keuhkokehän

Keuhkokehän refers to the anatomical term for the lung field, encompassing the entire area within the chest cavity occupied by the lungs. This term is commonly used in medical imaging, particularly in radiology, to describe the region where lung abnormalities are assessed. When a radiologist reviews an X-ray or CT scan of the chest, they examine the keuhkokehän for any signs of disease or structural changes.

The keuhkokehän includes not only the lung parenchyma itself, which is the functional tissue responsible for gas exchange, but also the surrounding structures within the thoracic cage. This includes the pleura, the membranes lining the lungs and the chest cavity, as well as the airways, blood vessels, and lymphatic channels within the lungs. The size and shape of the keuhkokehän can provide clues about overall lung health and can be affected by conditions such as emphysema, pneumonia, or pleural effusions.

In clinical practice, descriptions of findings within the keuhkokehän are crucial for diagnosis and treatment planning. For example, a radiologist might report the presence of infiltrates, nodules, or masses within the keuhkokehän, indicating potential infections, tumors, or other pathological processes. Understanding the boundaries and contents of the keuhkokehän is therefore fundamental to interpreting chest imaging and assessing pulmonary conditions.
