The short answer: PowerScribe 360 is the on-premises radiology reporting and dictation platform that most US imaging groups have used for years. It takes a radiologist's spoken findings, turns them into a structured report using the Dragon Medical speech engine, and lets the radiologist review, edit and sign the result into the patient record. Microsoft, which owns it through its acquisition of Nuance, is retiring it: annual renewals and maintenance ended August 31, 2026, and full support ends August 31, 2027. Its cloud successor is PowerScribe One.

If you have inherited a PowerScribe 360 system, joined a group that runs one, or started shopping for a replacement, it helps to understand exactly what the product is and where it sits in the reading workflow. This guide keeps it plain: what PowerScribe 360 does, how the dictation actually works, how it differs from PowerScribe One and from Dragon, and why 2026 is the year the question matters.
What is PowerScribe 360?
PowerScribe 360 is a radiology reporting platform: the software a radiologist uses to create the diagnostic report after reading a study. Its core job is turning dictated speech into a finished, structured report. A radiologist opens a case, reviews the images in the PACS viewer, speaks the findings and impression into a microphone, and PowerScribe converts that speech into text laid out in the group's report template. The radiologist edits and signs, and the signed report becomes part of the patient record and flows back to the ordering physician.
It came from Nuance, the speech-recognition company Microsoft acquired and folded into its healthcare division. "360" is the on-premises generation of the product line, installed on servers the imaging group owns and licensed as a purchase with annual maintenance. It has been one of the most widely deployed reporting systems in US radiology, which is exactly why its retirement is such a large event for the field.
How does PowerScribe 360 work?
The workflow is built around voice. When a radiologist speaks into the dictation microphone, PowerScribe uses the Dragon Medical speech recognition engine to transcribe the words in real time and drop them into the correct sections of a report template. Groups can run it a few ways: straight speech recognition with self-editing, speech recognition with delegated editing where a transcriptionist cleans up the draft, or macro-driven and auto-structured reporting where natural language understanding organizes the dictated content into a standard structure automatically.
Templates and AutoText are where the real value accumulates. Over years, a group builds a library of report templates and voice-triggered text snippets that encode how it likes to report each study type. That library is usually the single thing a group is most afraid of losing in any migration, because it represents thousands of hours of standardization. The assist, though, begins only once the radiologist is already reading and already talking. Deciding which study to read next, and catching the subtle finding, remains entirely the radiologist's job. Tools that begin earlier, at the worklist or in a drafted report, change the shape of the shift rather than just the speed of typing, which is the idea behind AI-assisted radiology reporting that drafts the structured report from the study before dictation starts.
Who makes PowerScribe 360?
Microsoft. The product was created by Nuance Communications, the company behind Dragon speech recognition. Microsoft acquired Nuance in 2022 and now sells and supports the PowerScribe line through its healthcare group. That matters for two reasons: the roadmap is set by Microsoft's priorities, which currently point firmly at cloud and subscription products, and the same company also owns Dragon and the DAX ambient documentation product, which are related but not the same thing.
What is the difference between PowerScribe and Dragon?
Dragon is the speech recognition engine; PowerScribe is the radiology reporting application built on top of it. Dragon Medical listens and turns speech into text in any clinical setting. PowerScribe wraps that transcription in everything radiology reporting specifically needs: report templates, AutoText macros, structured sections, worklist integration and the sign-off workflow. Put simply, Dragon is the ears and PowerScribe is the radiology-specific product around them. Microsoft's DAX is a third, different thing again: it listens to a spoken patient encounter and drafts a clinical note, so it has nothing to transcribe in a diagnostic image read. All three are Microsoft products, which is a common source of confusion.
Is PowerScribe 360 being discontinued?
Yes, in the way that matters to you. Microsoft has told customers that annual renewals and maintenance for PowerScribe 360 ended on August 31, 2026, and that full support ends on August 31, 2027. End-of-life notices went out in early 2026. The binaries will keep running after those dates, but there is no path to renew maintenance or get supported updates, and running unmaintained clinical software that handles protected health information becomes a compliance exposure your security team has to track and document rather than a decision you can quietly defer. For most groups, "we will just keep running it" stops being a real option.
What is the difference between PowerScribe 360 and PowerScribe One?
PowerScribe One is the cloud-hosted, subscription-priced successor to PowerScribe 360. The dictation experience is broadly familiar, but three things change: where the software runs (cloud instead of your own servers), how you pay for it (a recurring subscription instead of a perpetual license with maintenance), and who carries the uptime risk (the vendor and your internet connection rather than your local network). PowerScribe One also adds cloud speech recognition that vendor materials describe as not requiring the per-radiologist voice-profile training that 360 sites are used to, plus AI-assisted impressions. We break the two down feature by feature, including where the older one still wins, in our PowerScribe One vs 360 comparison.
| PowerScribe 360 | PowerScribe One | |
|---|---|---|
| Where it runs | On-premises, your servers | Cloud-hosted |
| How you pay | Purchase plus maintenance | Recurring subscription |
| Support status | Renewals ended Aug 31, 2026; support ends Aug 31, 2027 | Current, actively developed |
| Speech recognition | Local, per-radiologist voice training | Cloud, described as no profile training required |
What replaced PowerScribe 360, and what are the options?
Microsoft's answer is PowerScribe One, and for many groups that will be the path of least resistance: a familiar product family, a supported migration route that reuses existing 360 templates and content, and a vendor relationship already on paper. There is nothing wrong with choosing it. But a forced migration is the one moment in a decade when the cost of leaving is roughly the same as the cost of staying, because you do the template, integration and training work either way.
That symmetry is worth using. Three paths are genuinely open: move to PowerScribe One, move to another speech-based reporting platform, or ask whether dictation should still be the core of the reporting layer at all. If you are rebuilding templates and retraining radiologists regardless, it is the cheapest chance you will get to also fix worklist triage and finding flags. We lay out the full trade in our guide to a Nuance PowerScribe alternative, and the dated specifics of the retirement in PowerScribe 360 end of life. If your interest is the reporting layer specifically, our structured radiology reporting software page covers what a modern report draft should include before you ever start dictating.
Is PowerScribe 360 cloud-based?
No. PowerScribe 360 is on-premises software, installed and maintained on servers your organization owns and runs inside your own network. That is precisely what is changing: PowerScribe One moves reporting to the cloud. The on-premises model has one advantage worth naming, which is that an internet outage does not stop dictation because everything runs locally. The cloud model trades that for automatic updates, vendor-managed infrastructure and no local servers to maintain. Which matters more depends on your connectivity, your IT staffing and your tolerance for depending on a vendor's availability.
Where Radiological.ai fits
Radiological.ai is decision support built for the whole read rather than dictation alone. It flags suspected findings for your review, prioritizes the worklist so urgent studies surface first, and drafts the structured report into your template before you sit down, across X-ray, CT and MRI in one pane. If a PowerScribe migration is forcing you to re-examine your reporting layer anyway, it is worth comparing the whole workflow rather than the dictation step in isolation. It is decision support, not a diagnosis, and the radiologist reviews, edits and signs every study. You can try the illustrative sample above to see how a drafted report reads.
