Lumbar Puncture Training Models

Coronary artery calcium scoring is commonly used to assess cardiovascular risk by quantifying calcified plaque within the coronary arteries. As imaging volumes continue to increase, automated analysis tools offer the potential to reduce manual effort while maintaining consistent measurements.

The Stanford 3DQ Lab evaluated automated calcium scoring software by comparing its outputs against existing internal measurement workflows. The project focused on determining whether automated assessments could provide results comparable to those generated through established processes while supporting the needs of clinical interpretation.

Figure B. Scatter plot showing Pearson correlation between current software and Software 1 calcium scores (R² = 0.9926) from 508 exams, indicating strong agreement.

Analysis demonstrated a strong correlation between automated measurements and those produced through manual review. These findings suggested that automated processing could provide reliable calcium scoring results while improving efficiency for high-volume imaging workflows. Results were presented to radiologists, who supported further exploration of the approach.

Working with the software vendor, the 3DQ Lab helped develop customized reporting that incorporated additional measurements and presentation formats requested by radiologists. The proposed reporting structure was submitted for further technical review and demonstrated improvements over the default output available at the time.

Although the project was ultimately discontinued because of funding limitations and shifting organizational priorities, efforts to identify and evaluate automated calcium scoring solutions continue as demand for calcium scoring services increases.
