What is Chest X-Ray (PA) Interpretation?

Posteroanterior (PA) chest X-ray uses X-rays to image the chest. It is the first imaging modality requested in respiratory disease diagnosis and follow-up; it is fast, inexpensive and widely available.

Systematic interpretation includes assessment of technical quality (rotation, inspiration, penetration) and review of airways, lung parenchyma, pleura, mediastinum, heart and bone-soft tissue structures.

Pneumonia, pleural effusion, pneumothorax, suspected lung cancer, heart failure, tuberculosis and interstitial diseases are major detectable pathologies. A normal X-ray does not rule out disease; if clinical suspicion persists, CT may be needed.

Digital radiography and AI-assisted reading systems improve interpretation accuracy.

Symptoms

Chest X-ray is a diagnostic tool; reasons for ordering it:
Evaluation of cough, dyspnea and chest pain
Suspected fever and infection (pneumonia work-up)
Post-trauma chest assessment
Preoperative assessment
Follow-up of known lung disease

Risk Factors

Low-level radiation exposure (0.02 mSv)
Relative contraindication in pregnancy (can be performed with shielding when needed)
Risk of false reassurance (a normal film does not exclude disease)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When new or changing respiratory symptoms occur
  • When fever and cough coexist (suspected pneumonia)
  • After chest trauma

Treatment Methods

01
Chest X-ray is a diagnostic tool; treatment targets the detected pathology
02
Antibiotic therapy when pneumonia is identified
03
Thoracentesis and etiologic work-up in pleural effusion
04
Plan further studies (CT, biopsy) for a suspicious mass
05
Assessment of treatment response with follow-up films
