1. What is the diagnosis? There is a small right pleural effusion located posteriorly. This would be seen more clearly on soft tissue window.
2. What is the diagnosis? This is a normal chest CT. The size of the bronchi and pulmonary vessels are within normal limits.
3. What is the diagnosis? This is bilateral pulmonary fibrosis. Note the honeycombing pattern (more on the left side anteriorly), and the reticular shadowing (more on the right lung posteriorly).
4. What is the diagnosis? This is severe bronchiectasis in a patient with cystic fibrosis. Note the dilated bronchi and the considerably thickened bronchial walls. Tram-track sign and Signet ring sign are present in this image.
5. What is the diagnosis? There are bilateral pulmonary emboli, seen as filling defects within the distal left and right main pulmonary arteries as they branch.
6. What is the diagnosis? There are two large nodules in the right lung, as well as small bilateral pleural effusions. These findings are highly suggestive of metastases.
