Respiratory / Gastrointestinal / Cardiovascular / CNS
| Question | Answer |
|---|---|
| Cystic Fibrosis: | Additive - Mucus Production |
| Hyaline Membrane Disease: | Additive - Atelectasis (collapsed or airless condition) |
| Pneumonia: | Additive - Consolidation of lung parenchyma |
| Early Stage Lung Abscess: Late Stage Lung Abscess: | Destructive-Early abscess air-fluid level Additive - Late Pus Filled / |
| Primary Tuberculosis: Secondary Tuberculosis: | Destructive-Primary TB: trapped air before any consolidation. Additive-Secondary TB: Calcifications |
| Chronic Pulmonary Mycosis: Acute Pulmonary Mycosis: | Destructive-Chronic Stage due to cavitation. Additive-Acute Stage |
| Chronic Obstructive Pulmonary Disease: | Destructive-Looks like emphysema. (No change on x-ray in 50% of COPD cases) |
| Emphysema: | Destructive-Trapped Air |
| Pneumoconiosis: | Additive-Pulmonary nodules that become calcified and sometimes fuse together. |
| Neoplasms: | Additive - Growing pulmonary nodules, atelectasis, masses, and bronchial obstruction. |
| Metastatic Lung Disease: | (A) Fine and large nodules. May simulate edema |
| Atelectasis: | (A) Collapsed or airless condition |
| Pneumothorax: | (D) Appears hyperlucent. No pulmonary markings. |
| Pleural Effusion: | (A) Pleural Fluid |
| Empyema: | (A) Pus |
| Gastrointestinal: Ascites | (A) Fluid |
| Gastrointestinal: Emaciation | (D) Malnutrition or weight loss |
| Cardiovascular: Edema | (A) Fluid |
| Cardiovascular: Congestive Heart Failure | (A) Cardiac Enlargement |
| CNS: Metastatic (Brain) General | (D) Generally hypodense (low density) |
| CNS: Metastatic (Brain) Hemorrhage or calcifications within or next to the tumor | (A) Hyperdense if hemorrhage or calcifications |
