Radiology departments are critical to modern healthcare, yet reporting workflows remain slow, fragmented, and cognitively taxing. Radiologists switch between multiple screens, dictate findings line by line, and manually retrieve prior measurements or reports. Studies indicate that radiologists spend approximately 36% - 54% of their time on image interpretation, with the rest on administrative tasks (JACR, 2023). This imbalance not only reduces productivity, but also contributes to burnout and can affect patient outcomes.
Founded by practicing radiologist Avez Rizvi, RADPAIR aims to redesign radiology workflows. Today, RADPAIR represents 13-14% of the U.S. radiology reporting market, including its largest client, Radiology Partners, supporting 4,000 physicians across 40-50 million cases annually. Their mission is to enable next-generation, agentic AI workflows that orchestrate multiple AI agents from dictation to reasoning to system control so radiologists can prioritize patient care and high-value interpretations.
Traditional radiology workflows are fragmented and cumbersome:
Imaging → Switch screens → Report software → Dictate findings line by line → Manually retrieve prior reports → Compile measurements → Submit report
Key pain points:
STT-Specific Bottlenecks and Multi-Agent Requirements
Scaling AI-assisted transcription is particularly challenging, with constraints that impact physician adoption and workflow trust:
“Even if word error rate is low, missing a commonly used medical term can have huge consequences. Cloud latency disrupted dictation and workflow, making real-time AI unusable.”
Dr. Vikram Krishnasetty, Associate CMO at Radiology Partners
“Building agentic AI solutions in radiology is uniquely challenging—especially when orchestrating multiple workflows that span both inside and outside the reporting environment. From controlling external systems to retrieving and synthesizing data across diverse platforms, true orchestration requires seamless collaboration between specialized models.”
Avez Rizvi, CEO and Co-Founder, RADPAIR
These workflow and technical bottlenecks slowed throughput, increased operational costs, and threatened adoption of AI-assisted reporting, impacting the onboarding of new customers. The broader challenge: enabling natural, voice-driven orchestration across multiple AI agents in radiology workflows. And that starts with solving real-time reporting issues that erode physician trust and slowed documentation, creating inefficiencies that were clearly unsustainable for clinical teams.
RADPAIR is developing a modern SDK standard with the intent to open-source it that allows AI to act intelligently and safely across workflows:
Here is the AI-enabled workflow (powered by Fireworks):
| Step | Actor | Action |
|---|---|---|
| 1 | Radiologist | Dictates findings naturally |
| 2 | Fireworks AI | Hosts RADPAIR’s STT model, provides real-time transcription, streaming, and low-latency multi-model orchestration |
| 3 | RADPAIR | Populates structured report. Fetches prior reports/measurements. Updates viewports/images. Performs safety checks. Finalizes report. |



The table below highlights the contributions of Fireworks and RADPAIR within the AI-enabled workflow.

Downstream tasks including populated structured reports, retrieving prior studies, updating viewports and safety checks are orchestrated by RADPAIR, leveraging the transcription Fireworks provides.
Fireworks enables RADPAIR to deploy AI-assisted, multi-agent radiology workflows at scale, letting radiologists focus on interpreting images while patients benefit from faster, more accurate diagnoses.
Before: Fragmented Workflows and Distrust in AI
Imaging → Switch screens → Report software → Dictate findings → Fetch prior reports → Compile measurements → Submit report
Before RADPAIR’s speech engine was optimized, radiologists experienced significant latency between speaking and seeing finalized text appear in the transcript. Cloud-based speech engines often introduced noticeable delays compared to locally installed systems, interrupting dictation flow and breaking concentration. In addition, editing and correcting transcript errors was cumbersome, and cloud-processing artifacts occasionally produced hallucinated or misplaced words—further reducing reliability and trust in real-time reporting.
After: Reliable, Real-time AI Reporting at Scale
Radiologist speaks → [RADPAIR’s hosted STT model on Fireworks] Real-time transcription → [RADPAIR] Populates structured report → [RADPAIR] Retrieves prior reports & measurements → [RADPAIR] Updates viewports → [RADPAIR] Performs safety checks → Finalize report
Radiologists dictate naturally; AI transcribes shorthand and specialized terms in real time, populating structured reports instantly. Physicians focus on interpretation, not troubleshooting technology.
Fireworks provides the infrastructure to host and scale RADPAIR’s fine-tuned STT and other AI models, enabling sub-second, near-real-time transcription and model orchestration (<200ms intermediate display), which supports RADPAIR’s delivery of accurate transcription while preventing missed words, hallucinations, and macro misfires. RADPAIR’s orchestration layer handles multi-tasking, error-checking, and audit logging so radiologists can focus on high-value interpretation rather than troubleshooting technology. The result: faster throughput, higher accuracy, and restored physician trust in AI-assisted reporting.
Impact on physicians and healthcare operations:
Human and Clinical Impact:
“We’re at a point in radiology facing a 35% workforce deficiency nationally. Patients wait longer for reports, and there aren’t enough radiologists. We want to do everything on the tech front to increase capacity, reduce burnout, and enable radiologists to perform at the top of their license. They shouldn’t be secretaries and transcriptionists. Working with RADPAIR— and through their partnership with Fireworks — has been key to pushing this forward. Now, radiologists can dictate naturally and have AI keep up in real time, which is a major leap forward,”
Dr. Vikram Krishnasetty, MD, Associate CMO, Radiology Partners
