Radiology practices replacing an aging PACS, the system that stores and displays medical images, often compare New Lantern and Sirona Medical. Both are San Francisco companies that put the worklist, the image viewer, reporting, and AI into one cloud system that runs in a web browser. New Lantern is the younger company, and its Curie assistant drafts much of each report for the radiologist to edit and sign. Sirona Medical sells RadOS, which also includes a PACS archive and can run on top of a practice's current systems or replace them.
Independent radiology groups that want worklist, image viewer, and AI report drafting in one cloud system
Large health systems that need a long record of enterprise PACS installations
Groups reading for many hospitals that want one workflow across them
Hospitals that need the software installed on their own servers
| Axis | New Lantern | Sirona Medical |
|---|---|---|
| What it replaces | Replaces separate PACS, reporting, and worklist tools with one platform and a single login. | Stronger Can sit on top of the current PACS or replace it, under one of three subscription options. |
| AI report drafting | Stronger Curie takes measurements, compares prior studies, and pre-drafts up to 75 percent of each report in the radiologist's own wording. |
AI drafts the impression section of the report, and AI tools from several other vendors can run inside the same system. |
| Image archive and advanced imaging | Includes a cloud PACS viewer, and New Lantern is registered with the FDA as a Class I image communications device. | Stronger Includes a PACS archive and an Advanced Imaging Suite, cleared by the FDA in October 2025, that adds PET-CT support. |
| Size of its biggest customers | Customers include Central Illinois Radiological Associates, whose more than 93 radiologists read for more than 26 hospitals and clinics. | Stronger Everlight Radiology signed a five-year deal in May 2026 to move its 800 radiologists in six countries onto RadOS. |
| Company track record | Benchmark led a $19 million Series A in November 2024. | Stronger Raised a $22.5 million Series A, a $40 million Series B, and a $45 million Series C, and launched RadOS publicly in November 2023 after five years with partner practices. |
| Getting the practice live | Stronger Scores 7.2, and it needs a plan to move old images out of the current PACS. |
Scores 6.9, and it needs an executive owner for a larger change to the practice's systems. |
| Knowing what you will pay | Scores 6.6, quoted by study volume, radiologists, sites, image storage, and migration, with no public price list. | Stronger Scores 7.0, quoted under one of three named subscription options, with no public price list. |
“My group switched to New Lantern in January. Cloud based PACs and dictation. Initially speech recognition was meh for some members of the group but has significantly improved since learning and speech training.”

“They don't integrate with third party reporters, one of the core strengths of their product are the worklist automations built natively in between their viewer and reporter”

“I see and integrate dozens of PACS a year. They’re. Okay. They have a ways to go before I’d call them mature.”

New Lantern is for an independent radiology group that is adding sites quickly, wants AI to draft most of each report, and is ready to replace its PACS, worklist, and reporting tools at once. Sirona Medical is for a larger practice or teleradiology group, meaning a group that reads scans remotely for many hospitals, that wants one cloud platform across all of them and the option to keep its current PACS at first.
Walk away from both if you only want an AI add-on for the reporting system you use today. Walk away from New Lantern if you want AI that detects disease on images, since Curie does not detect or diagnose disease. Walk away from Sirona Medical if your hospitals require software installed on their own servers.
