Study Notes
Introduction to Chest Radiology
- The learning objectives of this topic include understanding the modalities used in chest imaging and identifying common pathology.
Basic Principles of X-ray
- Understanding anatomy and how X-rays make an image is crucial for radiology.
- A PA (posterior-anterior) chest X-ray is taken with the X-ray beam passing from back to front, whereas an AP (anterior-posterior) X-ray is taken from front to back, which is not ideal.
CXR Acquisition
- Rotation, inspiration, and penetration are important factors to consider when acquiring a CXR.
- The CXR should be taken in inspiration, and the lungs should be fully expanded.
Systematic Approach
- Use the ABCDE approach to evaluate a CXR:
- A: Airway (check for tracheal straightness, narrowing, and foreign bodies)
- B: Breathing (evaluate lung expansion, symmetry, and periphery)
- C: Circulation (asses cardiac size, position, and hilar vessels)
- D: Disability (examine bones and soft tissues)
- E: Everything else (look for lines, tubes, and abnormalities in areas not covered by A-D)
CXR Evaluation
- Airway: Check for tracheal straightness, narrowing, and foreign bodies.
- Breathing:
- Evaluate lung expansion, symmetry, and periphery.
- Look for nodules, airspace, and interstitial changes.
- Circulation:
- Assess cardiac size, position, and hilar vessels.
- Evaluate the aortic arch, main pulmonary artery, and left atrial appendage.
- Disability:
- Examine bones and soft tissues.
- Look for abnormalities in the diaphragm, ribs, and sternum.
- Everything else:
- Check for lines, tubes, and abnormalities in areas not covered by A-D.
- Evaluate the apices, behind the heart, and below the diaphragm.
CT and Other Modalities
- CT: Provides better sensitivity and specificity than CXR, used for cancer suspicion and pulmonary embolism evaluation.
- CTPA: Used to diagnose pulmonary embolism.
- VQ scan: Used to diagnose pulmonary embolism, especially in young patients.
- PET/CT: Used for cancer staging scans.
- Echocardiogram: Excellent initial investigation for heart failure and pericardial effusion.
- Coronary angiogram: Used to diagnose coronary artery disease and deploy stents.
- CT coronary angiogram: A less invasive way to diagnose coronary artery disease.
