Pulmonary Blood Volume Quantification from CT Scans for Hypertension Assessment

376 patient records from the Cambridge PH Registry link AI-derived pulmonary artery and vein volumes from CT scans with anthropometric and hemodynamic factors. The data includes patients with a median age of 60 years, 57% female, across five diagnostic categories. Hakim Ghani published this secondary analysis on figshare in May 2026.

Use Cases

• Modeling the effect of height, weight, and body surface area on pulmonary blood volume based on the described anthropometric associations.
• Investigating sex-related differences in pulmonary vascular volumes using the described normalization strategies.
• Assessing the incremental predictive value of anthropometrics for pulmonary vascular resistance and cardiac output as described in the hemodynamic models.
• Training or validating segmentation models for pulmonary arteries and veins from computed tomography pulmonary angiography (CTPA) scans.

Strengths

• Includes 376 patients with right heart catheter data, a key invasive measurement.
• Covers five distinct diagnostic categories of pulmonary hypertension and a no-PH control group.
• Analysis adjusts for multiple confounders including pulmonary vascular resistance, diagnostic category, and cardiac comorbidities.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 23.6 KB file size suggests the dataset is likely a summary document, not the raw underlying data.
