Summary

This study tests whether a special CT scan with contrast dye can give clearer images of tumors during radiation therapy. Twenty adults with advanced cancer will receive the extra scan alongside their standard treatment. The goal is to see if this approach is feasible and improves tumor visibility.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: intravenous contrast dye (iodinated)
What this could lead to: If successful, this could improve how doctors see tumors during radiation, potentially leading to more precise treatment.
What could go wrong: This is a very small, early feasibility study with only 20 people. It tests imaging, not treatment, so it won't directly improve outcomes. There is a small risk of allergic reaction to the contrast dye.
