Frequently Asked Questions

How do these tools integrate into a radiologist's existing workflow, and what is the depth of their integration with PACS/RIS/EHR systems?

a2z-Unified-Triage is designed to integrate into existing hospital and imaging center workflows by flagging and prioritizing seven urgent findings on abdomen-pelvis CT scans to move suspected emergencies to the top of the worklist in minutes. It also offers AI-assisted preliminary report drafting. AI-Rad Companion Engine offers seamless integration with PACS, RIS, and imaging modalities, focusing on automating post-processing and generating DICOM structured reports that can flow into reporting templates.

What specific clinical performance metrics, beyond efficiency gains, can be provided to demonstrate the accuracy and sensitivity of each tool in identifying relevant pathologies?

a2z-Unified-Triage flags and prioritizes seven urgent findings on abdomen-pelvis CT scans, with an average AUC of 0.989, demonstrating near-perfect accuracy in discriminating between positive and negative cases. It has demonstrated high sensitivity and specificity across these conditions, validated against U.S. board-certified radiologist ground truth. AI-Rad Companion Engine enhances diagnostic precision through automated segmentation of anatomical structures and lesions, volumetric analysis, and automated measurements of key indicators like coronary calcium and lung nodules. For chest X-ray analysis, AI-Rad Companion has shown high accuracy with AUCs of 95-99% for target radiographic findings, and can offer superior sensitivity for detecting lung lesions, consolidations, and atelectasis compared to written reports.

For which specific clinical scenarios or sub-specialties would each tool provide the most significant clinical value?

a2z-Unified-Triage is particularly valuable for Emergency Medicine, General Surgery, and Radiology, focusing on urgent triage of abdomen-pelvis CT scans for critical conditions like small bowel obstruction, acute cholecystitis, and free air.
