Chest Radiographs Loyola University Stritch School of Medicine Drs. Pierce and Demos Loyola University Medical Center Department of Radiology
Radiographs • Free Intraperitoneal Gas • Pneumothorax • Pleural Effusion • Pulmonary Edema
Free Intraperitoneal Gas Free Air
Upright chest Left lateral decubitus abdomen Free Intraperitoneal Gas
58-year-old man with acute abdominal pain Supine abdomen Free air under right hemidiaphragm Upright abdomen Neonate with distended abdomen Supine abdomen Free Intraperitoneal Gas
Free Intraperitoneal Gas • When diagnosis is uncertain • If the patient can stand • Upright chest and abdomen • If the patient can not stand • Left lateral decubitus abdomen radiograph • Most sensitive • Computed tomography
Skin fold extends outside ribs Skin Fold Pneumothorax Displaced Visceral Pleura Pneumothorax Displaced pleura (arrows) Look for displaced Visceral Pleura
Tension Pneumothorax TENSION PNEUMOTHORAX ** Examine patient * Look for deviated heart and mediastinum, depressed hemidiaphragm * Compare to previous radiographs
Supine Patient Medial Pneumothorax
Before….No pneumothorax After….Pneumothorax Supine PatientDeep Sulcus Sign
Is there a pneumothorax or isn’t there? • Order a Lateral Decubitus chest radiograph • With the side of the chest in question as the upside • Possible left pneumothorax get right lateral decubitus chest • Look for displaced visceral pleura along upside lateral chest wall • Order Upright Expiratory chest radiograph • Look for pneumothorax at lung apex
Upright…Meniscus Supine…Unilateral increased density Decubitus…Effusion layered on downside Pleural Effusion
Semiupright…..Lung base opacity fades superiorly Pleural Effusion 63-year-old man recovering from congestive heart failure…Effusion loculated in fissure
Massive Pleural Effusion or Total Lung Atelectasis Total Atelectasis Heart and mediastinum shifted toward whited out hemithorax Massive pleural effusion Heart and mediastinum shifted away from whited out hemithorax
Pleural Effusion • Most sensitive way to show pleural effusion • Decubitus chest radiograph • Least sensitive way to show pleural effusion • Supine chest radiograph
Normal pulmonary vessels Interstitial pulmonary edema Alveolar pulmonary edema Septal (Kerley B) lines due to interstitial pulmonary edema are thickened interlobular septae Pulmonary Edema
Pulmonary Edema • Interstitial pulmonary edema • Poorly defined pulmonary vessels • Visible lung fissures • Septal lines • Thick bronchial walls • Alveolar pulmonary edema • Bilateral symmetric perihilar lung consolidation • Enlarged heart, Pleural effusion COMPARE TO PREVIOUS RADIOGRAPHS
