The CT-images demonstrate the atelectasis of the left upper lobe (blue arrow). The use of either clinical probability adjusted or age adjusted D-dimer interpretation has led to … As mentioned before bronchopneumonia starts in the bronchi and then spreads into the lungparenchyma. Notice the abnormal right border of the heart. The most common causes of atelectasis are: Sometimes lobar atelectasis produces only mild volume loss due to overinflation of the other lungparts. On HRCT there are four patterns: reticular, nodular, high and low attenuation (table).
