New scanner could speed up fracture diagnosis with less radiation
NCT ID NCT01796600
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study tested whether a cone-beam CT scanner (Newtom 5G) can detect and classify fractures of the arms and legs as accurately as a standard CT scan. 43 adults with suspected fractures received both scans. Researchers compared how well each scan identified the type of fracture and any nearby soft-tissue damage. If proven effective, this technology could offer a quicker, lower-radiation option for diagnosing broken bones.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Cone-beam CT scanner (Newtom 5G)
- What this could lead to
- If successful, this could offer a faster, lower-radiation alternative to standard CT for diagnosing broken bones in arms and legs.
- What could go wrong
- This is a small, completed study with only 43 participants, so results may not apply to everyone. The cone-beam scanner may not detect all fractures or soft-tissue injuries as well as standard CT.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patient age 18 years old or above, weight ≤ 160 Kg * Patient require MDCT for a suspected distal limb fracture or a preoperative assessment * French spoken an read * Free and informed consent signed * Being affiliated to a French social security system or similar. Exclusion Criteria: * Patients already included in the study for a previous fracture * Patient with severe pain and reduced spontaneous mobility that could prevent proper positioning for the cone-beam * Lack of effective contraception (risk of pregnancy) or pregnancy proven data on interrogations * Patient on protection of the court, under supervision or trusteeship * Inability to express a consent * Patients already enrolled in a study with a conflict of interest with this study. * The presence of osteosynthesis materiel or capital may interfere with image quality. A sample of 3 to 5 patients may be included at the beginning of the study to test the image quality in presence of material.
