Pulmonary Consolidation Size Measurements from Standard and Low-Dose Tomosynthesis

A retrospective study of 49 patients (mean age 66 years) with 75 lung consolidations, comparing size measurements from standard and low-dose digital chest tomosynthesis against computed tomography. Data includes 147 image series (49 CT and 98 DTS) from a previous investigation, with measurements performed by four senior radiologists. The dataset was published by Masoud Jadidi on figshare in May 2026.

Use Cases

• Validate low-dose tomosynthesis accuracy for lung consolidation sizing based on the described comparison with CT.
• Assess inter-observer reliability in radiological measurements based on the described multi-observer study design.
• Train or benchmark machine learning models for automated lesion measurement based on the described image series and reference annotations.

Strengths

• Includes 147 image series (49 CT and 98 DTS) from 49 patients, providing a direct comparison basis.
• Measurements were performed by four senior radiologists, enabling inter-observer reliability analysis with reported ICC values >0.90.
• Explicitly compares two radiation dose levels (standard 0.13 mSv and 30% reduced 0.09 mSv) for the same consolidations.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale model training.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal and patient population bias inherent to the single retrospective study.
