If the alveoli and small airways fill with dense material, the lung is said to be consolidated. If there is an area that is different from the surrounding ipsilateral lung, then this is likely to be the abnormal area. Once you have spotted asymmetry, the next step is to decide which side is abnormal. Asymmetry of lung density is represented as either abnormal whiteness (increased density), or abnormal blackness (decreased density). Remember many lung diseases are bilateral and symmetricalĪssess the lungs by comparing the upper, middle and lower lung zones on the left and right.The whiter side is not always the abnormal side.Compare an area of abnormality with the rest of the lung on the same side.Compare the left and right upper, middle and lower lung zones. ![]()
