Nanox AI Alternatives and AI Coronary Calcium Scoring Software for Routine Chest CT

The short answer

The main Nanox AI alternatives for coronary calcium scoring are Bunkerhill iCAC, Coreline AVIEW CAC, Riverain ClearRead CT CAC, Imbio CAC Software and HeartLung AI-CVD, plus scanner-console calcium scoring from Siemens, Canon and GE. For bone health, compare Bunkerhill BMD and HeartLung ABMD with Nanox HealthOST. Radiological.ai fits at the report rather than the score, flagging suspected findings and drafting confirmed coronary calcification with the practice's recommendation language for radiologist review; it does not compute an Agatston score, bone density value or liver fat value.

Nanox describes HealthCCSng, HealthOST and HealthFLD as its population health suite for routine CT. According to Nanox, HealthCCSng measures and visualizes coronary calcified plaque on non-contrast, non-ECG-gated chest CT, HealthOST addresses bone health, and HealthFLD addresses liver fat on routine chest and abdomen CT. The buying question is whether the hospital needs these scores together or a specific application for its existing imaging workflow.

Distribution matters as much as the product name. A September 2025 deepc press release describes HealthCCSng, HealthOST and HealthFLD as available on deepcOS. A November 2025 press release describes a Nanox reseller agreement with 3DR Labs. These are attributed distribution announcements, so buyers should ask which applications, interfaces and support responsibilities are included in the proposed contract.

Buyers comparing Nanox AI alternatives weigh a single vendor for coronary calcium, bone health and liver fat against choosing each application separately. A CAC shortlist includes Bunkerhill, Coreline, Riverain, Imbio and HeartLung, alongside scanner-console options. Gated, non-gated and contrast CT are separate evaluation questions. Bone health brings Bunkerhill BMD and HeartLung ABMD into the comparison. Ask each vendor to demonstrate the exact intended use, PACS or platform fit and output format. Nanox publishes no public price, so a quote must define its scope before it supports a meaningful comparison.

Radiological.ai addresses the report workflow. It reads X-ray, CT and MRI, flags suspected findings as decision support, prioritizes the worklist, measures findings the radiologist confirms, compares the prior and drafts the structured report into the practice's own template. It does not calculate CAC, bone density or liver fat values and makes no FDA clearance claim. For incidental coronary calcification, its role is to put confirmed findings and the practice's recommendation wording into fixed positions in the draft, including the impression. The radiologist reviews, edits and signs every report.

Nanox AI compared with calcium scoring alternatives and reporting support

Match the application and acquisition protocol to the clinical task, then compare integration, purchasing evidence and the final report.

What to compare	Nanox AI	CAC alternatives and Radiological.ai
Scope of scores	Nanox describes a population health suite covering coronary calcified plaque with HealthCCSng, bone health with HealthOST and liver fat with HealthFLD.	Compare Bunkerhill iCAC, Coreline AVIEW CAC, Riverain ClearRead CT CAC, Imbio CAC Software and HeartLung AI-CVD for CAC. Radiological.ai supports findings and report drafting without computing these scores.
FDA clearance record	The record contains 12 clearances across Zebra Medical Vision, Nanoxai and Nano-X AI. Relevant entries include HealthCCSng K210085 (September 15, 2021) and K241440 (August 19, 2024), HealthOST K213944 (April 22, 2022) and HealthFLD K233080 (February 8, 2024).	CAC records include Bunkerhill iCAC K230223 (April 25, 2023), AVIEW CAC K243696 (February 14, 2025), ClearRead CT CAC K242188 (December 3, 2024), Imbio K230112 (June 13, 2023) and AI-CVD K252029 (December 19, 2025). Radiological.ai makes no FDA clearance claim.
Gated, non-gated and contrast CAC	Nanox describes HealthCCSng for non-contrast, non-ECG-gated chest CT. Do not extend that description to gated or contrast studies without checking the applicable indication.	Bunkerhill has separate iCAC, CAC (gated) Algorithm K240369 and Contrast CAC K260166 records. Check acquisition coverage for every alternative, including Siemens, Canon and GE console software. Radiological.ai does not calculate a calcium score on any protocol.
Bone density	HealthOST is Nanox's vendor-stated bone health application for routine CT, with clearance K213944.	Bunkerhill BMD K242295 (April 8, 2025) and HeartLung ABMD K213760 (July 29, 2022) are alternatives to evaluate for the bone measurement task. Radiological.ai does not compute a bone density value.
Liver fat	Nanox describes HealthFLD as measuring liver fat on routine chest and abdomen CT. Its clearance is K233080.	A CAC or bone density clearance does not establish liver fat coverage. Request a named liver application and its indication if that is a requirement. Radiological.ai does not compute a liver fat value.
Buying and distribution	Press releases describe availability through deepcOS in September 2025 and a 3DR Labs reseller agreement in November 2025. Confirm which modules the proposed purchase includes.	Ask alternative vendors to specify the purchasing route, platform dependencies and PACS output. Radiological.ai works alongside PACS over DICOM and returns results over HL7 or FHIR.
Federal purchasing record	The USAspending recipient search for Zebra Medical, Nano-X and Nanox returns zero federal prime awards. This search result does not establish the absence of other purchasing routes.	VA calcium scoring software orders range from $13,468 to $67,660. Bunkerhill's GSA award is for AI in medical and imaging, not a CAC purchase. Do not use it as CAC pricing evidence.
Public price	No published price list. Request an itemized quote for the selected applications, integration, support and contract term.	No scoring vendor in this category publishes a price list. Radiological.ai Practice covers X-ray and CT at $199 per reading radiologist per month billed annually, or $399 month to month. This is reporting support pricing, not CAC scoring pricing.
What reaches the report	Nanox describes measurement and visualization of coronary calcified plaque. Ask to see how the result reaches the radiologist and the signed impression.	Radiological.ai drafts confirmed coronary calcification and recommendation language in fixed positions within the practice's own report template. The radiologist reviews, edits and signs. It provides no Agatston score.

Side by side

Radiological.ai vs Nanox AI (formerly Zebra Medical Vision), honestly

A fair look at what each does well. Both are capable tools. Here is where they differ.

What matters	Radiological.ai	Nanox AI (formerly Zebra Medical Vision)
Coronary calcium measurement	Flags suspected findings as decision support and drafts confirmed coronary calcification. Does not compute an Agatston score.	Nanox describes HealthCCSng as measuring and visualizing coronary calcified plaque on non-contrast, non-ECG-gated chest CT.
Bone and liver values	Does not compute a bone density or liver fat value. Evaluate dedicated scoring software when those outputs are required.	Nanox describes HealthOST for bone health and HealthFLD for liver fat as part of its population health suite.
Report workflow	Drafts the structured report into the practice's template, including confirmed findings and the practice's recommendation language in fixed positions.	Evaluate the scoring output and ask how it enters the report, including whether the impression requires a separate step.
PACS and platform fit	Works alongside PACS over DICOM, with results returned over HL7 or FHIR. Compares the prior and prioritizes the worklist.	Press releases describe deepcOS availability and a 3DR Labs reseller agreement. Confirm interfaces and responsibility for support in the quote.
Pricing basis	Practice covers X-ray and CT at $199 per reading radiologist per month billed annually, or $399 month to month.	No public price. Ask for itemized application licenses, deployment, interfaces, support and renewal terms.
Review and clearance	Decision support with no FDA clearance claim. The radiologist reviews, edits and signs every report.	The openFDA record identifies cleared devices across the Zebra and Nanox names. Match the specific device and indication to the planned clinical use.

Comparison reflects general, publicly understood positioning. Capabilities change, so check each product for the latest.

For the broader chest CT workflow, compare AI CT scan analysis with AI lung nodule detection. A nodule workflow and a coronary calcium workflow can share a study while requiring different applications. The ClearRead CT comparison covers the lung nodule decision alongside the wider product family.

Use the radiology AI regulatory guide when checking device names, K numbers and intended use. For procurement, AI calcium scoring software cost examines the purchasing question. Compare the reporting support plans on Radiological.ai pricing with a scoring vendor's itemized quote, keeping the different deliverables explicit.

For buyers searching for Nanox AI reviews, the evidence here is the clearance record, attributed vendor descriptions and federal purchasing search, rather than a customer rating. Ask for a demonstration using the protocols and report template your practice actually uses. Verify the scoring result, PACS delivery and final impression separately before deciding whether the proposed workflow meets your requirements.

Why groups pick Radiological.ai

One assistant across the whole read

Choose the required output first

A numeric coronary calcium score, a bone density value and a drafted impression are different deliverables. Specify which outputs your screening workflow requires before choosing a vendor. Nanox brings coronary calcium, bone health and liver fat applications into its vendor-stated suite. Dedicated alternatives let buyers evaluate each measurement separately. Radiological.ai supports the report without replacing the scoring application.

Check protocols against the named device

Ask the vendor to map the proposed software to your gated, non-gated, non-contrast and contrast protocols. The Bunkerhill record includes separate gated and contrast CAC devices. Nanox describes HealthCCSng for non-contrast, non-ECG-gated chest CT. A portfolio clearance count alone cannot establish coverage for every acquisition, and a console application needs its own compatibility review.

Keep public orders in context

VA software purchases include Siemens order 36C25718P2756 for calcium scoring software and hardware at $67,660, Trillamed order 36C25721P0490 for calcium scoring software at $19,909, and Canon order 36C24522F0407 for Vitrea vScore at $13,468. These are order-specific amounts. Bunkerhill's GSA award concerns AI in medical and imaging, not CAC. Neither that award nor the VA range establishes Nanox pricing.

Make the impression part of the evaluation

The 2017 SCCT/STR guideline recommends evaluating and reporting CAC on all noncontrast chest CT and accepts a visual ordinal estimate. Decide how confirmed coronary calcification and the practice's recommendation wording reach the impression. Radiological.ai drafts those elements in fixed positions within the practice's template. The radiologist reviews the findings, edits the draft and signs every report.

Good questions

Nanox AI (formerly Zebra Medical Vision) vs Radiological.ai, answered

The main CAC alternatives are Bunkerhill iCAC, Coreline AVIEW CAC, Riverain ClearRead CT CAC, Imbio CAC Software, HeartLung AI-CVD and Siemens, Canon or GE scanner-console scoring. For bone health, compare Bunkerhill BMD and HeartLung ABMD. Radiological.ai supports confirmed findings and report drafting rather than computing those scores.

Yes, Nanox AI is formerly Zebra Medical Vision. The openFDA search spans Zebra Medical Vision, Nanoxai and Nano-X AI applicant names and identifies 12 software clearances across them. Match the device name and K number to the proposed application. Nanox.ARC hardware clearances are separate from this software record.

Yes, HealthCCSng has FDA 510(k) records K210085 dated September 15, 2021, and K241440 dated August 19, 2024. Nanox describes it as measuring and visualizing coronary calcified plaque on non-contrast, non-ECG-gated chest CT. Ask for the applicable indication and confirm that your proposed protocols fall within its scope.

Nanox AI publishes no public price, so an itemized vendor quote is necessary. Ask it to identify HealthCCSng, HealthOST and HealthFLD separately, the licensing basis, deployment, PACS or platform interfaces, support, contract term and renewal conditions. VA calcium scoring orders provide purchasing context, not a Nanox subscription price.

FDA records include Nanox HealthCCSng, Bunkerhill iCAC and its separate gated and contrast CAC applications, Coreline AVIEW CAC, Riverain ClearRead CT CAC, Imbio CAC Software and HeartLung AI-CVD. The table lists their K numbers and dates. Check each device's intended use rather than assuming every acquisition protocol is covered.

Yes, software exists for coronary calcium analysis on non-gated chest CT. Nanox describes HealthCCSng for non-contrast, non-ECG-gated chest CT, and Bunkerhill has an iCAC device record. Confirm the specific output and cleared indication. The 2017 SCCT/STR guideline also accepts a visual ordinal estimate when evaluating and reporting CAC.

No, Radiological.ai does not calculate an Agatston score. It flags suspected findings and drafts the report so confirmed coronary calcification and the practice's recommendation reach the impression. The draft uses the practice's template and fixed positions for those elements. The radiologist reviews, edits and signs every report.

Bunkerhill BMD and HeartLung ABMD are bone density alternatives to evaluate alongside HealthOST. Their FDA records are K242295 dated April 8, 2025, and K213760 dated July 29, 2022, respectively. Compare the intended use, supported CT protocols and output requirements. Radiological.ai does not compute a bone density value.
