AI reads CT scans to measure muscle and fat: will it beat the experts?
NCT ID NCT07600866
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new AI software called Soma that automatically measures muscle and fat from CT scans. Researchers will compare the software's measurements to those made by three expert radiologists using 200 CT scans from public databases. The goal is to see if the AI is accurate enough to help diagnose conditions like muscle loss (sarcopenia) and obesity.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Soma Body-Composition Segmentation Software (diagnostic test)
- What this could lead to
- If successful, this software could help doctors quickly and accurately measure muscle and fat from CT scans, aiding in the diagnosis of conditions like sarcopenia and obesity.
- What could go wrong
- This is a small, early validation study using existing scans, not a real-world test. The software may not perform as well in different hospitals or on different types of patients.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Subjects older than 16 years old whose de-identified abdominal CT imaging is available from one of six publicly accessible imaging datasets (autoPET, AMOS, MSD Pancreas, CT-ORG, ENHANCE.PET, RATIC). The 200-scan study cohort is selected by stratified sampling from a curated pool of 2,066 scans to ensure representation across BMI category, age band, sex, body region (abdomen-only vs. whole-body), and clinical context (oncologic vs. non-oncologic).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Subjects above 16 years or older at the time the source imaging was acquired. * De-identified abdominal computed tomography (CT) scan available from one of the six predefined publicly available datasets (autoPET, AMOS, MSD Pancreas, CT-ORG, ENHANCE.PET, or RATIC). * Scan covers the third lumbar vertebra (L3) with a contiguous axial slice suitable for L3-level body-composition analysis. * Demographic metadata required for stratified sampling (age, sex; BMI where available; clinical context as encoded in source dataset) is present. Exclusion Criteria: * Subject under 16 years of age at the time the source imaging was acquired. * Scan does not include the L3 vertebra or has severe motion artifact, truncation, or metallic artifact precluding analysis at the L3 level. * Duplicate or near-duplicate scans of the same subject already included in the cohort. * Missing demographic metadata required for at least one stratification axis.
