The basic requirements for the window when shooting lung ct images are as follows

When taking CT images of lung, it is necessary to take the lung window and mediastinal soft tissue window.

It is very important to use lung window and mediastinal soft tissue window when shooting lung CT images. The setting of lung window can highlight the lung structure, provide clear contrast of lung tissue, and help to find and diagnose lung diseases, such as lung parenchyma lesions and pulmonary nodules. Mediastinal soft tissue window emphasizes the contrast of soft tissue in mediastinum, which is helpful for doctors to observe mediastinal organs and lymph nodes, and is of great significance to find mediastinal lesions and lymphadenopathy. The combined use of these two windows can provide comprehensive anatomical information, which is helpful for accurate diagnosis and treatment planning.
