Chest CT Coronal Scan is a reconstruction of the coronal plane after a tomography scan of the chest. In order to better study the human body, three planes are fictionalized in medicine based on the different orientations of a person when standing, the coronal plane is the plane seen from the front when a person is standing. Chest CT coronal scanning images show different planes “cut” from the front to the back of the chest, in order to observe whether there are any disease changes in the chest and how they occur. Chest CT coronary scan can show the trachea, bronchial bifurcation, right and left main bronchus, right middle bronchus in full length, and can observe the bronchial lumen, wall and its extra-tubular related structures. Due to the large density difference, it is more convenient to observe, similar to the chest orthopedic X-ray; however, it is more effective than the X-ray examination. If you feel unwell, you should go to the hospital in time and consult a specialist for guidance.
