The DGSCOPE system is indicated for the review of diagnostic medical images produced by DICOM-based multimodality sources. These sources may include, but are not limited to, radiological diagnostic systems, picture archival computers (PACS), and processing workstations. The DGSCOPE system displays the processed images using an integrated computer. The DGSCOPE's PC's surfaces can be disinfected using an FDA approved liquid disinfectant indicating that the use of the DGSCOPE system is appropriate in an operating room environment. The display of CT, MR, X-Ray, NM, US, and other diagnostic data is in the standard planar and pseudo-three dimensional formats in both static and dynamic review modes. This device is not used in the primary diagnosis of Mammography images.
Not Found
The provided text is a 510(k) premarket notification approval letter for the DGSCOPE, Release 1.0 device. This document primarily focuses on the regulatory approval and indications for use, rather than detailed performance studies or statistical metrics. As such, most of the requested information regarding acceptance criteria, study details, and performance metrics is not available in the provided text.
Here's what can be extracted and what is missing:
1. A table of acceptance criteria and the reported device performance
Not available in the provided text. This document is an approval letter, not a performance report.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Not available. The document does not describe any specific test sets or data provenance.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not available.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not available.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not available. The DGSCOPE is described as a device for "review of diagnostic medical images" and "displays the processed images." There is no mention of AI assistance or a comparative effectiveness study involving human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not available. The DGSCOPE is described as a display system, not a standalone diagnostic algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not available.
8. The sample size for the training set
Not available.
9. How the ground truth for the training set was established
Not available.

Dear Dr. Briandet:
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 (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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such 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.
Image /page/0/Picture/9 description: The image shows a logo with the text "1906-2006 FDA Centennial" inside a circular border. Below the logo, the text "Protecting and Promoting Public Health" is written in a decorative font. The logo appears to be a commemorative emblem for the FDA's centennial anniversary. The text below the logo emphasizes the organization's mission to safeguard and improve public health.

§ 892.2050 Medical image management and processing system.
(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)
Classification. Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).
