Intended Use
CDM Insights is a post-processing image analysis software that assists trained healthcare practitioners in viewing, analyzing, and evaluating MR brain images of adults > 45 years of age. CDM Insights provides the following functionalities: - Automated segmentation and quantitative analysis of individual brain structures and white matter hyperintensities - Quantitative comparison of brain structures and derived values with normative data from a healthy population - Presentation of results for reporting that includes numerical values as well as visualization of these results
Device Story
CDM Insights is post-processing software for MR brain images; accepts DICOM inputs. Performs automated segmentation/quantification of brain structures and white matter hyperintensities; conducts post-acquisition analysis of diffusion-weighted imaging (DWI) data; compares patient metrics against normative data from healthy populations. Deployed as a cloud solution; produces DICOM-encapsulated PDF reports with numerical values, graphs, and anatomical color overlays. Used by radiologists and neurologists to assist in clinical evaluation; output supports clinical decision-making by providing quantitative brain morphometry and lesion data. Benefits include standardized, objective assessment of brain structures and longitudinal tracking of metrics.
Clinical Evidence
Bench testing only. Accuracy of segmentation and cortical surfaces validated against gold standard (US board-certified neuroradiologists) using 60 cases (healthy, Alzheimer's, MCI, frontotemporal dementia, MS). Mean Dice overlap for white matter hyperintensities was 0.66 (SD 0.15), exceeding 0.58 criterion. Regional cortical Dice scores ranged 0.58-0.72, all passing 0.58 threshold. Repeatability tested on 121 individuals; reproducibility tested on >1500 subjects (aged 45-90). Percentile accuracy tested on ~2000 independent scans.
Technological Characteristics
Medical image management and processing software. Cloud-based deployment. Inputs: DICOM MR images (T1-weighted, FLAIR, DWI). Outputs: DICOM-encapsulated PDF reports, numerical data, color overlays. Complies with ISO 13485, ISO 14971, IEC 62304. Software-based segmentation and quantification algorithms.

# Dear Yulia Nikova:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
{1}------------------------------------------------
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (OS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
