CT-Based Body Composition Analysis with Contrast Medium Influence

A translational study analyzes the impact of intravenous contrast medium on CT-based body composition assessment. The dataset includes volumetric analysis from 20 Göttingen minipigs and 114 tri-phasic human CT scans, measuring muscle radiodensity and adipose tissue volumes. The research was authored by Luca Salhöfer and last updated on 2026-05-08.

Use Cases

• Assess the robustness of muscle volume quantification based on CT scans across different contrast phases.
• Evaluate the susceptibility of muscle radiodensity measurements to contrast medium interference.
• Compare surrogate markers for myosteatosis, such as inter- and intramuscular adipose tissue volumes, between non-contrast and contrast-enhanced scans.
• Validate imaging biomarkers for body composition analysis in translational animal and human models.

Strengths

• Includes data from 20 animal subjects and 114 human CT scans for validation.
• Measures multiple body composition features, including muscle radiodensity and volumes for five adipose tissue types.
• Explicitly compares six different CT scan phases (Non-contrast and five contrast-enhanced).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 2.2 MB DOCX document, which may not be a standard data format for analysis.
