Pathology - Chest Flashcards
What is Emphysema? How does it show up in Xray? Exposure adjustment?
Lung’s alveoli become distended and there is an increase in air spaces distal to terminal bronchioles; dyspnea is primary symptom
Depressed diaphragm, radiolucent lungs, incresaed retrosternal air space (barrel-shaped chest)
Decrease exposure
What is Chronic Obstrutive Pulmonary Disease (COPD)? Exposure adjustment?
Group of disorders that cause chronic airway obstruction
Decrease
What is Pleurisy? How does it show up on Xray? Exposure adjustment?
Inflammation of the pleural; pain is on one side or the other and along intercostal nerve roots
Possible air-fluid levels, or none with “dry” pleurisy
No adjustment
What is Pleural Effusion? How does it show up on Xray? Exposure adjustment?
Excess fluid in pleural cavity
Increased radiodensity; air-fluid levels, possible mediastinal shift
Increase in exposure
What is Hemothorax? How does it show on an Xray? Exposure adjustment?
Plueral effusion containing blood
Increased radiodensity; air-fluid levels, possible mediastinal shift
Increase in exposure
What is a Pneumothorax? How does it show on an Xray? Exposure adjustment?
Free air is trapped in the plural space caused by penetrating chest trauma or blowout of bleb
Strip of radiolucency with no lung markings
No exposure adjustment
What is Atelectasis? How would it show up on an xray? Exposure adjustment?
Collapse of all or part of lung
Radiodense lung regions with shift of heart and trachea
Increase exposure
What is congestive Heart Failure (CHF)? What causes CHF? Exposure adjustment?
Heart is unable to propel blood at a sufficent rate and volume - results in insufficient blood supply to the tissues
Hypertension
Increase
What is Coronary Artery Disease? What does it cause? Exposure adjustment?
Plaque accumulates in the arteries, reducing blood supply to heart.
Ischemia and myocardial damage
No adjustment
What is a Cerebrovascular Accident (CVA)? What causes a CVA? Exposure adjustment?
Stroke; Atherosclerotic disease affecting blood supply to the brain
Brain hemorrhage
Infraction
Embolism
No adjustment
What is an Aneurysm? And what causes it? Exposure adjustment?
Ballooning or out-pouching of a vessel wall as a result of weakining
Atherosclerotic disease, trauma, infection, or congenital defects
No adjustment
What is Pneumonia? What does it look like on an xray? Expsosure adjustment?
Inflammation of the lungs resulting in accumulation of fluid
Patchy infiltrate wth increased radiodensity
Increase exposure
Dyspnea
Shortness of breath
Hemoptysis
Coughing up blood
What are the most common forms of COPD?
Emphysema and chronic bronchitis
