Table 2_Paired dosimetric comparison of VMAT-based total body and total marrow irradiation

Sevim Sahin's dataset contains paired dosimetric comparisons of Volumetric Modulated Arc Therapy (VMAT) plans for total body irradiation (TBI) and total marrow irradiation (TMI) in 30 adult acute leukemia patients. The data was generated retrospectively using the same CT datasets, with TMI target delineation facilitated by AI-based auto-segmentation. It was last updated on 2026-06-02 and is shared under a CC-BY-4.0 license.

Use Cases

• Compare organ-at-risk dose reduction between TBI and TMI based on the paired dosimetric results described.
• Analyze plan complexity metrics like monitor units and modulation factor for VMAT-based radiotherapy techniques.
• Evaluate the potential role of AI-based auto-segmentation in skeletal target delineation for TMI planning.
• Investigate dose homogeneity and organ sparing in leukemia treatment conditioning regimens.

Strengths

• Data is based on a paired comparison of 30 patient cases, allowing for direct statistical analysis.
• Plan quality was assessed using specific metrics: homogeneity index, monitor units, segment number, and modulation factor.
• Results show statistically significant (p < 0.001) dose reductions to organs like the heart, kidneys, and liver.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• The dataset is very small at 19.3 KB, indicating limited scope.
