The device description explicitly states that Quantib Prostate is an extension to the "Quantib AI Node software platform" and mentions "automatic processing module that performs prostate and prostate sub-reqion segmentation". While the specific AI/ML algorithms aren't detailed, the platform name and the nature of the automatic segmentation strongly suggest the use of AI/ML.
No
The device is image post-processing software that provides tools for visualization, analysis, and interpretation of prostate MRI images, assisting trained medical professionals in diagnosis. It explicitly states that "Diagnosis should not be made solely based on the analysis performed using Quantib Prostate." This indicates it's a diagnostic aid, not a therapeutic device.
No
The software provides tools to assist in the interpretation of prostate MR studies and states that "Diagnosis should not be made solely based on the analysis performed using Quantib Prostate." This indicates it's an interpretative aid, not a diagnostic device.
Yes
The device description explicitly states that Quantib Prostate is "image post-processing software" and an "extension to the Quantib Al Node software platform." The modules described are all software-based functionalities for processing, visualization, and analysis of existing MRI images. There is no mention of any accompanying hardware component that is 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 medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Quantib Prostate's Function: Quantib Prostate processes and analyzes medical images (MRI scans) of the prostate. It does not perform tests on biological samples.
- Intended Use: The intended use clearly states it's for "image post-processing software" to "facilitate the analysis and study review of MR data sets."
- Device Description: The description focuses on image processing modules, segmentation, registration, and visualization of MRI data.
While the software provides information that assists in clinical interpretation and diagnosis, it does so by analyzing imaging data, not by performing tests on biological specimens. This places it outside the scope of an In Vitro Diagnostic device.
No
The input indicates "Control Plan Authorized (PCCP) and relevant text: Not Found", meaning the letter does not contain explicit language stating the FDA has reviewed and approved or cleared a PCCP for this device, which is required by the Key Decision Rules.
Intended Use / Indications for Use
Quantib Prostate is image post-processing software that provides the user with processing, visualization, and editing of prostate MRI images. The software facilitates the analysis and study review of MR data sets and provides additional mathematical and/or statistical analysis. The resulting analysis can be displayed in a variety of formats, including images overlaid onto source MRI images.
Quantib Prostate functionality includes registered multiparametric-MRI viewing, with the option to view images combined into a single image to support visualization. The software can be used for semi-automatic segmentation of anatomical structures and provides volume computations, together with tools for manual editing. PI-RADS scoring is possible using a structured workflow.
Quantib Prostate is intended to be used by trained medical professionals and provides information that, in a clinical setting, may assist in the interpretation of prostate MR studies. Diagnosis should not be made solely based on the analysis performed using Quantib Prostate.

Non-clinical performance testing:
Bench testing of the software was done to show that the system is suitable for its intended use and to evaluate the stand-alone performance of the sub-region segmentation algorithm. This was done by comparing the automatic sub-region segmentation to a ground truth and calculating the Dice overlap and Mean Surface Distance. To place the agreement between the automatic method and the manual segmentation into context, the results are compared with the inter-observer measurements using statistical tests.
Clinical performance:
The clinical performance test of the sub-region prostate segmentation and the ROI localization initiation as seen by the user in a clinical context is conducted in a qualitative manner. Radiologists were asked to score the sub-region segmentations and ROI initial localizations using a 5-point Likert scale.

The semi-automatic prostate segmentation is extended with an algorithm to divide the prostate segmentation into sub-regions (central gland, peripheral zone, and urethra), without impacting the original prostate segmentations are displayed in the mpMRI analysis user interaction step and can be exported as a secondary capture series that also includes the ROI segmentations. Internal boundaries of subregions cannot be edited, but user edits of the outer prostate segmentation are reflected in the sub-region outer boundaries. Individual volumes of sub-regions are not provided.
