Lung Checks: New Rules, Fewer Worries?

Wed Jul 16 2025

Updates to the Lung-RADS System (2022)

The Lung-RADS system received an update in 2022, changing how doctors interpret certain findings on lung scans.

  • Old System: Findings might be labeled as 4B, leading to additional tests.
  • New System: Some cases are now labeled as 0, potentially reducing unnecessary stress.

Study Findings

A study reviewed over 14,000 lung scans under both old and new rules:

  • Old Rules: 0.4% of scans were labeled 4B (possible infection or inflammation).
  • New Rules: 0.8% were labeled 0 (same reason).

While the new system flags more cases, most were benign.

Key Benefits of the New Rules

  • Fewer False Alarms: None of the 0 cases turned out to be cancer.
  • Reduced Follow-Ups: The new system avoids unnecessary scans for certain findings, such as:
  • Ground-glass nodules
  • Tree-in-bud nodules

Conclusion

The updated Lung-RADS system aims to:

  • Minimize unnecessary tests
  • Ensure patients receive the right care

This means less stress and better outcomes for everyone involved.

questions

    Are the changes in Lung-RADS classifications influenced by external factors such as insurance companies or pharmaceutical industries?
    How does the increased usage of Lung-RADS 0 in v2022 impact the overall efficiency of lung cancer screening programs?
    If Lung-RADS 0 is so benign, why doesn't it come with a 'get out of follow-up free' card?
