Clinical Performance Tradeoffs of ChatGPT-5.2 Thinking (OpenAI) Compared with Radiologist Interpretation in Biopsy-Referred Mammography: Cancer Detection, False Positives, and Laterality
This study evaluates ChatGPT-5.2 Thinking (OpenAI) against human radiologists in biopsy-referred mammography, focusing on cancer detection, false positives, and laterality. Mammograms aid early breast cancer detection, but interpretation variability can lead to missed cancers or unnecessary tests. The study compared AI and breast radiologists using standard mammogram images from a biopsy-referred cohort.
Results showed that the AI program identified more cancers (higher sensitivity) but also generated substantially more false-positive classifications (lower specificity) and had only moderate accuracy in identifying the correct breast side. Specifically, ChatGPT-5.2 had a sensitivity of 95.08% compared to radiologists' 81.97%, but its specificity was only 10.26% versus radiologists' 56.41%. Overall accuracy for AI was 62.00% versus 72.00% for radiologists.
These findings suggest that while AI can improve cancer detection, its high false-positive rate and moderate laterality accuracy limit its use as a stand-alone tool. Instead, it is best suited as a concurrent aid or prioritization tool to support radiologists, necessitating further improvements in specificity and laterality before widespread prospective validation.

Sensitivity, Specificity, Accuracy, Laterality calculated
| Metric | ChatGPT-5.2 Thinking | Radiologist |
|---|---|---|
| Sensitivity | Higher (95.08%) | Lower (81.97%) |
| Specificity | Markedly Lower (10.26%) | Higher (56.41%) |
| Overall Accuracy | Lower (62.00%) | Higher (72.00%) |
| False Positives | Significantly more (35) | Fewer (17) |
| Laterality Accuracy (malignant cases) | Moderate (60.66%) | Implicitly higher (not explicitly reported for comparison but assumed to be clinical standard) |
Understanding AI's False Positives
While AI showed high sensitivity, many of its false-positive detections corresponded to benign structures or peripheral artifacts, indicating misclassification rather than true lesion recognition. This highlights the need for improved AI specificity and contextual understanding.
- AI struggles with differentiating benign structures from suspicious masses.
- Peripheral artifacts can trigger false positive flags.
- Human oversight remains crucial for contextual judgment and reducing unnecessary callbacks.

Your AI Implementation Roadmap
A phased approach to successfully integrate ChatGPT-5.2 Thinking into your breast imaging practice, leveraging its strengths while mitigating limitations.
Phase 1: Pilot & Validation
Implement ChatGPT-5.2 as a 'second-look' aid in a pilot program. Focus on integrating into existing workflows without replacing radiologist interpretation. Collect feedback on false positives and laterality errors. Validate against local pathology standards.
Phase 2: Specificity & Laterality Refinement
Work with AI vendors or internal teams to address identified false-positive patterns and laterality limitations. Focus on augmenting training data with benign look-alikes and enforcing side-aware constraints. Explore fusion with other imaging modalities (e.g., tomosynthesis) to mitigate density effects.
Phase 3: Prospective Integration & Monitoring
Roll out AI as a triage or concurrent-aid tool with clear escalation rules. Continuously monitor key performance indicators such as recall rate, biopsy yield, and time to diagnostic resolution. Implement periodic review of discordant cases and transparent reporting to oversight bodies.
Phase 4: Scaling & Advanced Features
Explore scaling AI to broader screening populations after achieving robust specificity and laterality. Investigate integration with other LLMs or mammography-specific AI systems for comparison. Ensure equitable performance across diverse patient subgroups and acquisition settings. Address data privacy and governance considerations.
