CT scan of heart shows obstruction of lung

Narrative
CTA chest, noncardiac portion Indication: Chest pain/anginal equivalent. Technique: Axial CTA slices through the chest were obtained at the level of the heart after the administration of contrast. Approximately 85 mL of Omnipaque 350 intravenous contrast was administered. Axial MIPS were created. Total DLP for the study is approximately 1367 mGy cm. Automated exposure control was utilized. Findings: The lung apices are partially excluded. No significant pericardial effusion is seen. Scattered subcentimeter in short axis dimension lymph nodes in the included mediastinum and hila are seen. The superior mediastinum is excluded from the field of imaging. The axilla are incompletely included in the field of imaging. The included lungs demonstrate no evidence of dense consolidation, pneumothorax, or significant pleural effusion. Mild dependent changes in the included lungs are noted. There are reticulonodular opacities in the posterior predominant right greater than left lower lobes and inferior right middle lobe which may reflect sequelae of infectious/inflammatory process. Atypical infection should be considered. The included upper abdomen demonstrates no definite acute abnormalities.There is a partially visualized tiny layering calculus within the incompletely visualized gallbladder on image 42 of series 8. Degenerative changes affect the visualized spine.
