Chest Xray Flashcards
Consolidation/ infiltrate
Substance denser than air such as fluid pus or blood. Pulmonary infiltrates associated with pneumonia and TB
Silhouette sign
Loss of normal borders between thoracic structures. Something is next to the heart that shouldn’t be there
Opacity
Bright
Lucency
Dark areas
Interstitial lung markings
Strings or lines and small dots through the lungs
Radiolucent
Xray with low density objects (like air), appears black/ darker
Radiopaque
Xrays that absorb high density ( like bone), appears light grey
What are the standard radiograph views for chest xray
-Posteroanterior (PA)
-Supine Anterposterior (AP)
-Lateral projection ( left or right side standing up)
Lateral decubatus ( left or side supine)
How should a PA be done
Patient sits or stands in upright position and must be taken when patients lungs are full during inspiration
What should you be cautious with when getting an AP done
Heart appears magnified
How should a lateral decubatus be done and what’s can it help diagnose
Patient lies on left or right side
Can diagnosis suspected or known fluid accumulation like pleural effusion
What is the normal ETT placement
2cm or 1 inch above the carina or at the aortic notch
NBRC: 2-6 cm above the carina
What are the signs of CHF
Kerly B’s
Batwing
Big heart
What could cause a tracheal shift towards the affected sites
Atelectasis
What could cause a tracheal shift away from the site
Pneumothorax and pleural effusion
What does blunting of the costophrenic angles suggest
Pleural effusion
What does the absence of pleural markings suggest
Pneumothorax
Where does subcutaneous emphysema form
Under the skin ( trapped air= crispy sound)
What’s a high resolution ct
Each cat scan provides an image of what a slice through the body looks like
What is a prefers choice in diagnosis of a pulmonary embolism
CTPA
