a2z Radiology AI gains FDA approval for unified abdomen-pelvis CT triage system

USA—a2z Radiology AI, based in the USA, has received clearance from the US Food and Drug Administration (FDA) for its innovative a2z-Unified-Triage device, designed to identify and prioritize seven urgent conditions on abdomen-pelvis CT scans simultaneously.

This device uniquely integrates detection of multiple acute findings into a single streamlined system, improving radiology workflow efficiency.

The a2z-Unified-Triage system flags critical conditions such as small bowel obstruction, acute pancreatitis, acute cholecystitis, acute diverticulitis, free air, hydronephrosis, and unruptured abdominal aortic aneurysm within a single pass of abdomen-pelvis CT images.

By combining these seven major emergencies into a single platform, it enables rapid detection and prioritization for faster patient care.

According to a2z Radiology AI, this system represents the first single device in the U.S. approved to triage multiple urgent findings on abdomen-pelvis CT scans simultaneously.

Pranav Rajpurkar, co-founder and associate professor at Harvard Medical School, explained that the goal was to create a generalist AI tool capable of scaling across various acute conditions.

He emphasized that they began with high-impact emergencies where prompt triage leads to significant improvements in patient outcomes.

Each year in the United States, more than 20 million abdomen-pelvis CT scans are performed, and the volume continues to increase.

To address this demand, the a2z-Unified-Triage tool quickly identifies suspected emergencies and elevates them to the top of radiologists’ worklists within minutes.

This rapid prioritization aims to ensure that patients with urgent needs receive timely attention.

Co-founder and CEO Samir Rajpurkar added that five of the seven conditions included in the system’s scope are receiving AI triage capabilities in the U.S. market for the very first time.

He noted the company’s plans to expand beyond these initial seven conditions, highlighting ambitious scaling efforts to cover more urgent radiology cases.

Developed specifically for real-world radiology workflows, the a2z-Unified-Triage system integrates smoothly into existing practices.

The company is also developing advanced prototypes that extend AI capabilities across a wider range of conditions and anatomical areas, moving beyond urgent triage to support broader diagnostic processes.

As the radiology community prepares for RSNA 2025, the largest annual conference in the field running from November 30 to December 4, a2z Radiology AI showcases its leadership in abdomen-pelvis AI solutions.

Their first-of-its-kind system brings comprehensive triage capability to the U.S. market, handling seven urgent conditions in a single workflow, streamlining radiologists’ efforts, and potentially improving emergency care outcomes.
