Intended Use
Liver Suite is an aiding tool for the clinician to review multi-phase liver CT images following LI-RADS® guidelines. Liver Suite is designed to help analyzing liver lesions in patients with known or suspected hepatocellular carcinoma (HCC). It provides optimized series display and a guided workflow to assess relevant clinical features for user-defined observations, to enable computation of a LI-RADS score. It is intended for use by healthcare professionals. The clinician remains ultimately responsible for the final assessment and diagnosis based on state-of-the-art practices, clinical judgment and interpretation of liver images or quantitative data.
Device Description
Liver Suite is a medical software that offers a guided workflow for the review and assessment of multi-phase CT liver exams per LI-RADS® v2018 guidelines. It is designed to help analyze liver lesions in patients with known or suspected hepatocellular carcinoma (HCC) by providing optimized image display and assessment of intensity metrics related to the 3 major imaging features for LI-RADS scoring. Liver Suite takes phased contrast CT series as input. It only processes one exam at a time (no longitudinal analysis). Liver Suite guided workflow includes: Automatic phase identification of the four hepatic imaging phases: unenhanced, arterial, portal venous and delayed; Semi-automatic lesion contouring based on an initial deposition from the user, user selects applicable appropriate score (LRNC, LR-TIV, LR-1, LR-2 or LR-M) based on image review; A user interface to guide the user in the application of LI-RADS scoring guidelines v2018; User sets the features - non-rim APHE (Yes/No), Enhancing Capsule (Yes/No), Non-peripheral washout (Yes/No), Threshold growth (Yes/No/Not Applicable), Ancillary Features; Automated computation of intensity metrics to help characterize Arterial Phase -Hyper Enhancement (APHE), Washout and Capsule; Automated calculation of LI-RADS score (per LI-RADS v2018 guidelines) from user assessment of major and ancillary features; Display of all measurements in a table for review and export. Identification of hepatic phases is based on a model-based algorithm or can be set manually by the user. Semi-automatic contouring of the lesion is based on the Auto Contour feature and user input. The Auto Contour feature is already part of Volume Viewer (K041521). User sets LI-RADS major and ancillary features and compute associated LI-RADS score. To assist with the assessment of Arterial Phase Hyper Enhancement (APHE), Washout and Capsule, intensity metrics based on enhancement characteristics around the lesion are automatically computed. LI-RADS score is computed based on LI-RADS features using LI-RADS diagnostic table. User can edit the major features, add ancillary features or manually choose a different score.

Unknown
The document mentions a "model-based algorithm" for phase identification, which could potentially be an ML model, but it doesn't explicitly state that AI or ML is used. The description of the algorithm is not detailed enough to confirm the use of AI/ML.

No.
The device is described as an "aiding tool for the clinician to review multi-phase liver CT images" and "designed to help analyzing liver lesions". It provides a LI-RADS score and assists with assessment, but it does not directly perform any therapy or treatment.

Yes

The device is described as an "aiding tool for the clinician to review multi-phase liver CT images following LI-RADS® guidelines" and is "designed to help analyzing liver lesions in patients with known or suspected hepatocellular carcinoma (HCC)". It provides a "guided workflow to assess relevant clinical features...to enable computation of a LI-RADS score." The "Automated calculation of LI-RADS score (per LI-RADS v2018 guidelines) from user assessment of major and ancillary features" directly contributes to a diagnostic process, even though the clinician remains ultimately responsible for the final diagnosis.

Yes

The device description explicitly states "Liver Suite is a medical software" and details its functions as processing input CT series and providing a guided workflow and calculations. There is no mention of accompanying hardware components being part of the device itself.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Liver Suite software processes medical images (CT scans) of the liver. It does not analyze biological samples taken from the patient.
  • Intended Use: The intended use is to aid clinicians in reviewing and analyzing liver CT images and applying LI-RADS guidelines. This is an image analysis and interpretation tool, not a diagnostic test performed on a biological sample.

Therefore, the Liver Suite software falls under the category of medical imaging software or a clinical decision support tool, not an in vitro diagnostic device.
