Authorized purpose: Assist physicians in reviewing previously acquired lumbar-spine MRI by providing user-confirmed anatomy identification, segmentation, labeling, measurements, and reporting; it is not a diagnostic device.
Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.

Overview status: Source-reviewed overview
What does this software do?Authorized purpose: Assist physicians in reviewing previously acquired lumbar-spine MRI by providing user-confirmed anatomy identification, segmentation, labeling, measurements, and reporting; it is not a diagnostic device.
Which images or clinical context are in scope?Modality: MRI Anatomy or clinical context: Lumbar spine, including vertebral bodies L1-S1, intervertebral discs, cord canal, dural sac, nerve roots, and posterior arch. Input: Previously acquired T2-weighted DICOM lumbar-spine MRI images from patients 18 and older. The packet excludes pregnancy, postoperative complications, tumors, infections, and complex hardware.
Who uses it?Intended users: Physicians, including radiologists and neuro/orthopedic spine surgeons; the user must review and authorize measurements and draft reports.
What does the software produce?Output: Qualitative image viewing; segmentation and labels for lumbar-spine structures; quantitative measurements such as disc protrusion, intervertebral angles, vertebral-body and disc heights, anterolisthesis/retrolisthesis, lordotic angle, dural-sac diameter, and report export. User-confirmed settings and measurements control storage and reporting.
What is its most important limitation?Key limitation: Not for diagnosis or treatment recommendation; segmentations are not final outputs; the user must confirm or reject measurements, inspect labels and segmentations, and review and approve reports. Only the stated T2-weighted DICOM lumbar-spine inputs and labeled patient restrictions are supported.
Clinical takeaway
Clinical role: Assist physicians in reviewing previously acquired lumbar-spine MRI by providing user-confirmed anatomy identification, segmentation, labeling, measurements, and reporting; it is not a diagnostic device.
Evidence takeaway
Evidence from the reviewed source record: FDA K240793 reports three independent data sets: 255 patient images for ground-truth development, 575 for pass/fail criteria, and 238 testing patients/studies from five U.S. sites on GE, Philips, and Siemens 1.5T/3.0T MRI systems. Four independent experts compared unedited software outputs with expert ground truth. Endpoints were structure segmentation mean Dice/MDC and measurement mean absolute error (MAE); listed mean Dice values ranged from 0.911 to 0.993 with structure-specific 95% CIs, and measurement MAEs were below structure-specific limits. The packet states no human clinical study was conducted for premarket clearance.

Start with the authorized purpose, then verify how it fits your service line and reading workflow.
Exact purpose
Assist physicians in reviewing previously acquired lumbar-spine MRI by providing user-confirmed anatomy identification, segmentation, labeling, measurements, and reporting; it is not a diagnostic device.
Qualitative image viewing; segmentation and labels for lumbar-spine structures; quantitative measurements such as disc protrusion, intervertebral angles, vertebral-body and disc heights, anterolisthesis/retrolisthesis, lordotic angle, dural-sac diameter, and report export. User-confirmed settings and measurements control storage and reporting.
Not for diagnosis or treatment recommendation; segmentations are not final outputs; the user must confirm or reject measurements, inspect labels and segmentations, and review and approve reports. Only the stated T2-weighted DICOM lumbar-spine inputs and labeled patient restrictions are supported.
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
Use these fields to structure a vendor demo, security review, and implementation estimate.
Integration
DICOM image input and qualitative/quantitative report export are established; the packet does not establish a specific PACS, RIS, EHR, or routing interface.
Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version. Candidate literature without exact product and version linkage is not shown as product evidence.

Safety and lifecycle
Postmarket record
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
Postmarket safety review
The exact-identifier FDA recall query returned no native recall record for K240793. This limited result does not establish absence of recalls or other safety information and does not cover later versions, family records, MAUDE reports, corrections, or field notices.
Verify security and privacy controls: Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.
Verify training: Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.
Verify pricing and total cost: No public price or quote for the exact K240793 configuration was established in this review.
Verify reimbursement and coding relevance: No exact-product payer policy, coding instruction, or payment determination was established; eligibility must be evaluated by payer, site of service, and use case.
Verify local validation and lifecycle monitoring: Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.
