The Veuron-Brain-pAb2 is a software for the registration, fusion, display and analysis of medical images from multiple modalities including MRI and PET. The software aids clinician in the assessment and quantification of pathologies from PET Amyloid scans of the human brain. It enables automatic analysis and visualization of amyloid protein concentration through the calculation of standard uptake volume ratios (SUVR) within target regions of interest and comparison to those within the reference regions. The software is deployed via medical imaging workplaces and is organized as a series of workflows which are specific to use with radiotracer and disease combinations.
The Veuron-Brain-pAb2 is stand-alone software to automatically calculate the "Standardized Uptake Value Ratio (SUVR)" for quantitative analysis of amyloid PET. The calculated result is just used as a reference supporting the accuracy of the diagnosis of patients' dementia for the medical professional. It also helps with accurate visual interpretation through visualization functions. Various amyloid PET images can be processed by providing a variety of options for users to choose in the image process.
The provided text describes the Veuron-Brain-pAb2 device, a software for the registration, fusion, display, and analysis of medical images (MRI and PET) to aid clinicians in assessing and quantifying pathologies from PET Amyloid scans of the human brain. It enables automatic analysis and visualization of amyloid protein concentration through the calculation of standard uptake volume ratios (SUVR).
However, the document is a 510(k) summary and primarily focuses on demonstrating substantial equivalence to a predicate device (Veuron-Brain-pAb). While it mentions "bench testing" and that the "measurement tool performance meets its pre-defined requirements," it does not provide explicit details about specific acceptance criteria, reported device performance metrics against those criteria, or the study design (including sample size, ground truth establishment, expert qualifications, or adjudication methods) that would typically prove such acceptance.
Therefore, many of your requested details cannot be extracted from this document.
Here's a breakdown of what can and cannot be answered from the provided text:
1. A table of acceptance criteria and the reported device performance
- Cannot be fully provided. The document states, "Bench testing is done to show that the system is suitable for its intended use and that the measurement tool performance meets its pre-defined requirements. This did not reveal any issues with the system, demonstrating that the performance of Veuron-Brain-pAb2 is as safe and effective as its predicate device."
- This implies that there were pre-defined requirements (acceptance criteria) and that the device met them. However, the document does not list these specific acceptance criteria (e.g., accuracy thresholds for SUVR calculation, registration precision limits) or the quantitative results of the device's performance against them.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Cannot be provided. The document mentions "bench testing" but does not describe the test set size, its provenance, or whether it was retrospective or prospective.
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)
- Cannot be provided. The document does not describe the method for establishing ground truth for any test set or the involvement or qualifications of experts in such a process.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Cannot be provided. No adjudication method is described.
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
- Cannot be provided. The document does not mention an MRMC study or any assessment of human reader improvement with AI assistance. The device is described as aiding clinicians and providing automatic analysis but not specifically as an AI assistance tool in an MRMC context within this summary.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Partially addressed, but not with specific performance metrics. The device is described as "stand-alone software to automatically calculate the 'Standardized Uptake Value Ratio (SUVR)' for quantitative analysis of amyloid PET." This indicates that the core SUVR calculation is standalone. However, the document does not present specific standalone performance metrics (e.g., sensitivity, specificity, accuracy) for this calculation. It merely states that its performance "is as safe and effective as its predicate device."
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Cannot be provided. The document does not specify the type of ground truth used for performance evaluation.
8. The sample size for the training set
- Cannot be provided. The document does not mention a training set or its size.
9. How the ground truth for the training set was established
- Cannot be provided. No information about a training set or its ground truth establishment is present.
