The NeuroQ™-PET DP program is indicated to perform a quantitative analysis of FDG-PET brain scans using a ROI count method. NeuroQ™ 3.0 provides added functionality which allows for analyzing the difference between two FDG-PET brain studies for the same patient, calculating values within user defined regions of interest, and displaying CT and PET brain studies for the patient.
NeuroQ™ 3.0 has been developed to aid in the assessment of human brain scans through quantification of mean pixel values lying within standardized regions of interest, and to provide quantified comparisons with brain scans derived from FDG-PET studies of defined groups having no identified neuropsychiatric disease or symptoms, i.e., asymptomatic controls (AC). The Program provides automated analysis of brain PET scans, with output that includes quantification of relative activity in 240 different brain regions, as well as measures of the magnitude and statistical significance with which activity in each region differs from mean activity values of brain regions in the AC database. The program can also be used to compare activity in brain regions of individual scans between two studies from the same patient, between symmetric regions of interest within the brain PET study, and to perform an image fusion of the patients PET and CT data. This program was developed to run in the IDL operating system environment, which can be executed on any nuclear medicine computer systems which support the IDL software platform. The program processes the studies automatically, however, user verification of output is required and manual processing capability is provided.
The provided document is a 510(k) summary for NeuroQ 3.0, a display and analysis program for PET Brain studies. It details the device's intended use and substantial equivalence to a predicate device but does not contain detailed information about specific acceptance criteria or a dedicated study proving performance against such criteria for NeuroQ 3.0 itself.
Instead, it refers to the validation of the initial program, NeuroQ™ - PET DP, and states that "The validation for modifications in version 3.0 can be found in Item F, Testing & Validation of this 510(k)". However, Item F is not included in the provided text.
Therefore, many of the requested details cannot be extracted directly from the given information.
Here's what can be inferred or stated based on the provided text:
1. A table of acceptance criteria and the reported device performance
- Cannot be provided. The document refers to validation in "Item F, Testing & Validation" which is not included. It broadly claims "safety and effectiveness" based on in-house testing and clinical validation studies for the previous version, but no specific quantifiable acceptance criteria or performance metrics for NeuroQ 3.0 are given.
2. Sample size used for the test set and the data provenance
- Cannot be provided directly for NeuroQ 3.0. The document mentions "clinical validation studies submitted in our previous 510(k) K041022" for the initial program, but details for NeuroQ 3.0's test set are not present.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Cannot be provided. This information would typically be detailed within the "Testing & Validation" section (Item F) which is missing.
4. Adjudication method
- Cannot be provided. This information is not present in the given text.
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 explicitly stated for NeuroQ 3.0. The device is described as "a display and processing program to aid in the diagnostic interpretation" and not meant to "replace or eliminate the standard visual analysis." It performs automated analysis but requires "user verification of output." While it assists physicians, an MRMC comparative effectiveness study to quantify human reader improvement with AI assistance is not described in this summary.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Yes, implicitly. The device "provides automated analysis of brain PET scans" and "quantification of relative activity in 240 different brain regions, as well as measures of the magnitude and statistical significance." This suggests the algorithm performs an analysis independently of immediate human interaction, though "user verification of output is required." However, specific standalone performance metrics are not given.
7. The type of ground truth used
- Cannot be provided directly. The document refers to comparing patient studies to a "reference database" of "FDG-PET studies of defined groups having no identified neuropsychiatric disease or symptoms, i.e., asymptomatic controls (AC)." This suggests "normal" or "healthy" controls form a basis for comparison, but the specific type of ground truth for assessing the accuracy of its quantitative analyses (e.g., against pathology, clinical outcomes, or expert consensus on abnormal findings) is not detailed.
8. The sample size for the training set
- Cannot be provided directly. The document mentions an "AC database" (asymptomatic controls) used for comparison, but the size of this database, or any other specific training set for model development (if applicable to this type of analysis program), is not disclosed.
9. How the ground truth for the training set was established
- Implicit for the AC database: The text states the AC database consists of "FDG-PET studies of defined groups having no identified neuropsychiatric disease or symptoms." This implies a clinical assessment or screening process to confirm the asymptomatic status, which serves as their "ground truth" for normality. However, the specific methodology of this establishment is not detailed.

- Medical Device:
NeuroQ 3.0 -- Display and Analysis program for PET Brain studies.
Classification Name - System, Tomography, Computed, Emission
- Medical Device Equivalence:
NeuroQ™ - PET DP, Ref.510(k)#: K041022
- Device Description:
NeuroQ™ 3.0 has been developed to aid in the assessment of human brain scans through quantification of mean pixel values lying within standardized regions of interest, and to provide quantified comparisons with brain scans derived from FDG-PET studies of defined groups having no identified neuropsychiatric disease or symptoms, i.e., asymptomatic controls (AC). The Program provides automated analysis of brain PET scans, with output that includes quantification of relative activity in 240 different brain regions, as well as measures of the magnitude and statistical significance with which activity in each region differs from mean activity values of brain regions in the AC database. The program can also be used to compare activity in brain regions of individual scans between two studies
{1}------------------------------------------------
from the same patient, between symmetric regions of interest within the brain PET study, and to perform an image fusion of the patients PET and CT data. This program was developed to run in the IDL operating system environment, which can be executed on any nuclear medicine computer systems which support the IDL software platform. The program processes the studies automatically, however, user verification of output is required and manual processing capability is provided.
5. Intended Use and Potential Adverse Effect on Health:
The intended use of this program was to provide the physician with a program which would allow him to co-register and display brain PET scans and compare the patients study to a reference database. The program can also be used to compare the activity in brain regions of individual scans between two studies from the same patient, between symmetric regions of interest within the brain PET study, and to perform an image fusion of the patients PET and CT data. This program serves merely as a display and processing program to aid in the diagnostic interpretation of a patient's study. It was not meant to replace or eliminate the standard visual analysis of the PET brain scan. The physician should integrate all of the patients' clinical and diagnostic information, i.e. patients' history, quality control images, visual interpretation of the PET brain scan, and quantitative results, prior to making his final interpretation. This comprehensive processing technique (as with all diagnostic imaging) is not perfect, and will be associated with some false positive and false negative results. The previous validation of the program can be found in the 510(k) submission for NeuroQ™ - PET DP, Ref. 510(k) #: K041022. The validation for modifications in version 3.0 can be found in Item F, Testing & Validation of this 510(k) and the physician should be aware of the accuracy when integrating the quantitative results for his final interpretation. Therefore, this program has no direct adverse effect on health since the results represent only a part of the information, which the physician will utilize for his final interpretation. The final responsibility for interpretation of the study lies with the physician.
6. Marketing History:
There have been other medical device programs marketed in the past which perform similar functions to those performed by the NeuroQ™ 3.0 program. Most Nuclear Medicine manufacturers have programs that can co-register SPECT/PET data and some of them have programs for comparison of the patient's data to a reference database. NeuroQ™ 3.0 provides a program which executes in the IDL operating system environment and we believe is substantially equivalent to our previous version of NeuroQ™ - PET DP K041022. To our knowledge there have been no safety problems with NeuroQ™ - PET DP K041022 which has been in the marketplace since June 2004.
7. Conclusions:
The safety of this program has been determined through the various stages of software development which included the initial design, coding, debugging, testing, and validation. The effectiveness of the initial program, NeuroQ™ - PET DP, has been established in in-house testing and clinical validation studies submitted in our previous 510(k) K041022. Specific details and results concerning the validation of the
{2}------------------------------------------------
NeuroQ™ 3.0 program are listed in Item F, Testing & Validation. We contend that the method employed for the development and the final in-house validation results of this medical display software program, NeuroQ™ 3.0, have proven its safety and effectiveness. In our opinion, NeuroQ™ 3.0 program is substantially equivalent to our previous version of NeuroQ™ - PET DP program which has been cleared for marketing. NeuroQ™ 3.0 program is intended for the same purpose and raises no new issues of safety or effectiveness.
