    CT COLONOGRAPHY

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    CT Colonography is a CT image analysis software package which allows the visualization of 2D and 3D medical image data of the colon derived from DICOM 3.0 compliant CT scans for the purpose of screening of a colon to detect polyps, masses, cancers, and other lesions. It provides functionality for 2D/3D rendering, bookmarking of suspected lesions, synchronized viewing of supine & prone data sets, and an object oriented endoluminal display. In comparison to colonoscopy, this tool has an advantage of depth penetration due its 3D presentation capability. It is intended for use by Radiologists, Clinicians, and referring Physicians to process, render, review, archive, print, and distribute colon image studies.

    Device Description

    CT Colonography is an image analysis software package that includes all the required software that allows the user to study the inside, wall, and outside of the colon using CT-acquired helical images. The tool is laid out to facilitate the detection of colonic lesions. CT Colonography is an advanced visualization software option that provides endoluminal views of anatomical structures. The flexibility of this software allows the user to move interactively from air paths to inner vessels visualization and thus, it is not limited to inner navigation of structures as lungs and sinuses. Volume Analysis (includes both. CT/MR Windows Workstation, K913770 and 3D & Dentascan for Windows K923077) provides the base for Colonography, CTC/Nav2 and Nav2 alone, which allows an increase in the ease of use and productivity. Colonography, CTC/Nav2 and Nav2 alone, also use some options of Volume Rendering (AW Volume Render Option K972399), which allows the user to quickly isolate structure of interest and render volumetric data in three dimensions.

    AI/ML Overview

    The provided text does not contain detailed information about specific acceptance criteria or a dedicated study proving that the device meets those criteria. Instead, it focuses on establishing substantial equivalence to previously cleared devices.

    Here's an analysis based on the available information:

    1. Table of Acceptance Criteria and Reported Device Performance:

    The document does not explicitly state quantitative acceptance criteria or provide a table of reported device performance metrics against such criteria. The "Conclusions" section in {1} states: "The CT Colonography option (K023943) does not result in any new potential safety risks and performs as well as devices currently on the market." This suggests that the performance standard is to be equivalent to the predicate devices, rather than meeting specific numerical thresholds.

    2. Sample Size Used for the Test Set and Data Provenance:

    The document does not mention a specific test set, its sample size, or its data provenance (e.g., country of origin, retrospective or prospective nature). The safety and effectiveness claim is based on substantial equivalence to predicate devices, implying that their established performance is sufficient.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications:

    This information is not provided. Since no specific test set or study validating device performance is described, the process of establishing ground truth for such a set is not detailed.

    4. Adjudication Method for the Test Set:

    This information is not provided.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size:

    The document does not indicate that an MRMC comparative effectiveness study was conducted. The focus is on demonstrating that the CT Colonography software provides similar functionality and safety as the predicate devices.

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done:

    The document does not explicitly state whether a standalone algorithm performance study was done. The device is described as an "image analysis software package" intended for "Radiologists, Clinicians, and referring Physicians to process, render, review, archive, print, and distribute colon image studies," implying it is used with human interaction, not as a standalone diagnostic tool.

    7. The Type of Ground Truth Used:

    The document does not specify the type of ground truth used for any performance evaluation, as no such evaluation is detailed. Given the nature of CT Colonography for lesion detection, a typical ground truth would likely involve colonoscopy with biopsy/histopathology or surgical pathology.

    8. The Sample Size for the Training Set:

    The document does not mention a training set or its sample size.

    9. How the Ground Truth for the Training Set Was Established:

    This information is not provided, as no training set is discussed.

    Summary of Device Acceptance Rationale:

    The core of the acceptance for the "CT Colonography" (K023943) device is its substantial equivalence to two predicate devices:

    The manufacturer, GE Medical Systems, asserts that their CT Colonography option "does not result in any new potential safety risks and performs as well as devices currently on the market." This suggests that the acceptance criteria are met by demonstrating that the new device shares fundamental technological characteristics, intended use, and performance characteristics (as understood from the predicate devices) without raising new questions of safety and effectiveness. The "Conclusions" section acts as the primary statement on how the device meets "acceptance criteria" by equating its performance to already cleared devices.

    The FDA's clearance letter (pages {2} and {3}) confirms this approach, stating they "have determined the device is substantially equivalent... to legally marketed predicate devices." This regulatory pathway does not typically require extensive new clinical studies to prove performance against novel acceptance criteria, but rather a demonstration of similarity to existing safe and effective devices.

    Device Name :

    CT COLONOGRAPHY/NAVIGATOR2

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    CT Colonography/Navigator2 is an image analysis software package that contains CT Colonogarphy and Navigator2.

    CT Colonography allows the user to study the inside, wall and outside of the colon. It provides the user with an ability to view datasets from both, prone and supine positions, facilitating detection of colonic lesions. In comparison to colonoscopy, this tool has an advantage of non-invasive depth penetration due to its 3D presentation capability.

    Navigator2 provides endoluminal views of anatomical structures. Navigator2 is designed to enhance and modify current image quality, tools, speed and user interface of Navigator for improved productivity. Navigator2 provides a visualization tool to investigate structures (such as polyps, tumors, stones, calcification etc.) within anatomy, airways and organs. Thus. its viewing capability of the inner and outer surfaces of organs as well as within their walls provides additional supplemental information, complementing endoscopy/colonoscopy, to support interpretation and treatment planning. Navigation2 is applicable to X-ray as well as CTMR.
