New 4D scan could sharpen lung cancer radiation
NCT ID NCT01421953
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a special 4D PET-CT scan can help doctors better target radiation for lung cancer. Seven patients with non-small cell lung cancer received both a standard CT scan and a 4D PET-CT scan before radiotherapy. Researchers compared the tumor volumes identified by each scan to see if the 4D version provided more accurate information for planning treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to more precise radiation targeting for lung cancer, potentially reducing damage to healthy tissue.
- What could go wrong
- This is a very small, early-stage study with only 7 participants, so results may not apply to all patients. It focuses on planning, not treatment outcomes.
