The document describes automated analysis and quantification based on predefined regions of interest and comparisons to a database of asymptomatic controls, but it does not mention AI, ML, or related terms like neural networks or deep learning. The analysis methods described are consistent with traditional image processing and statistical comparison techniques.
No.
This device is an image analysis software used for diagnosis, not for treating any condition.
Yes
The device quantifies activity in brain scans to assist in the examination of neurodegenerative processes such as Alzheimer's disease and Parkinson's disease. It also quantifies differences between two studies for the same patient and compares regional activity values to asymptomatic control subjects, indicating its use in diagnosing or aiding in diagnosis.
Yes
The device is described as a "program" that runs in a software environment (IDL operating system) and processes existing image data (PET, SPECT, CT). The description focuses entirely on the software's functionality for image analysis, quantification, and comparison, without mentioning any associated hardware components that are 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 NeuroQ™ 3.8 program processes and quantifies data from imaging scans (PET, SPECT, CT) of the brain. It does not analyze biological samples taken from the patient.
- Intended Use: The intended use clearly states it's for quantifying activity in brain PET and SPECT scans and assisting in the examination of brain scans.
- Device Description: The description focuses on image processing, quantification of pixel values within regions of interest, and comparisons with databases of brain scans.
Therefore, while it's a medical device used in the diagnostic process, it falls under the category of medical imaging software rather than an In Vitro Diagnostic device.

Intended Use / Indications for Use
The NeuroQ™ 3.8 program is used to regionally quantify activity in brain PET and SPECT scans using a ROI count method. It displays co-registered PET, SPECT and CT images, along with output from quantification of activities reflecting regional concentrations of FDG, amyloid imaging agents, SPECT perfusion and dopamine transporter radiotracers, relative to activities in any of several user-selected reference regions or whole brain. It provides for displaying and quantifying the regional differences between two PET or SPECT brain studies for the same patient, or the levels of amyloid imaging agents retained in specified brain regions of a patient, and for assisting the user in the examination of brain scans acquired for assessing neurodegenerative processes underlying symptoms of cognitive and movement disorders by comparing regional activity values to each other and to those in brain scans acquired for asymptomatic control subjects. These neurodegenerative processes can be Alzheimer's disease, Lewy body dementia. Parkinson's disease with dementia, vascular dementia, and frontotemporal dementia.
The product is intended for use by trained nuclear medicine physicians. The clinician remains ultimately responsible for the final interpretation and diagnosis based on standard practices and visual interpretation of all SPECT and PET data.

Device Description
NeuroQ™ 3.8 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, to perform an image fusion of the patients PET and CT data, and to provide analysis of amyloid uptake levels in the brain. The program can also be used to provide a quantitative analysis of uptake levels in basal ganglia structures of the brain. 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.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical tests: Compared processing and output of substantially equivalent devices (Hermes (DATSCAN™) and General Electric (DaTQUANT™)). Both provide similar analysis as DaTSCAN analysis in NeuroQ v3.8, enabling visual evaluation and quantification of DaTSCAN images, and providing a normal database for relative quantification. They automatically define regions of interest over left and right basal ganglia and calculate uptake values for DaTSCAN.
Clinical tests: The safety and effectiveness of the initial program, NeuroQ™ - PET DP and NeuroQ™ 3.0, was established through in-house testing and clinical validation studies per previous 510(k)s K041022 and K072307. For basal ganglia analysis, inter-observer reproducibility of determining scans with/without reduced dopamine transporter and accuracy of the application were assessed. Inter-observer reproducibility was highly significant (e.g., ratios of right posterior putamen to right anterior putamen Pearson coefficient r=0.59, p=0.00002; ratios of left posterior putamen to left anterior putamen r=0.78, p

5. Indication for use and Potential Adverse Effect on Health:
The NeuroQ™ 3.8 program is used to regionally quantify activity in brain PET and SPECT scans using a ROI count method. It displays co-registered PET, SPECT and CT images, along with output from quantification of activities reflecting regional concentrations of FDG, amyloid imaging agents, SPECT perfusion and dopamine transporter radiotracers, relative to activities in any of several user-selected reference regions or whole brain. It provides for displaying and quantifying the regional differences between two PET or SPECT brain studies for the same patient, or the levels of amyloid imaging agents retained in specified brain regions of a patient, and for assisting the examination of brain scans acquired for assessing neurodegenerative processes underlying symptoms of cognitive and movement disorders by comparing regional activity values to each other and to those in brain scans acquired for asymptomatic control subjects. These neurodegenerative processes can be Alzheimer's disease, Lewy body dementia, Parkinson's disease with dementia, vascular dementia, and frontotemporal dementia.
The product is intended for use by trained nuclear technicians and nuclear medicine physicians. The clinician remains ultimately responsible for the final interpretation and diagnosis based on standard practices and visual interpretation of all SPECT and PET 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. 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.

Cybersecurity
The risks associated with cybersecurity and the NeuroQ™ medical device have been assessed and resolved to a satisfactory level. The risks are associated with the files or images being corrupted by a security breach. There are methods in place to prevent this corruption through MD5 checksums, encryption, multiple patient labels on output screens to allow for patient authentication by users, and using methods for compiling of code and interfaces that substantially reduce or eliminate the ability to corrupt the code. In addition, it is the responsibility of the local information technology personnel at the institution to implement the necessary security methods and procedures to restrict access to the computers and data stored on these systems. Some of these methods include limiting access to trusted users through user ID and passwords, implementing timed methods to terminate sessions, and using strengthen password protection methods. They should also ensure trusted content and implement methods for detection of security compromises and for retention and recovery.
New software versions as well as patches are compiled and moved to a known clean computer and are checked there for viruses and malware. Software is then packaged together into an installer which is signed with a key to ensure the installer remains intact throughout testing and on to distribution.
Validated software updates and patches are provided at least annually and whenever a cybersecurity risk is identified. Notification of availability of these patches is made through the software itself. These updates are delivered as signed installers that present signature information to the user to confirm validity of the source of the patch.
It is always recommended that the installation environment have adequate, updated antivirus and anti-malware scanners in place. It is also recommended that a firewall, by default, deny all inbound and outbound traffic on the network. At installation time, a list of ports and destinations for firewall exceptions is provided specific to each installation.
6. Marketing History:
There have been other medical device programs marketed in the past which perform similar functions to those performed by the NeuroQ™ 3.8 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™ 3.8 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, NeuroQ™ 3.0 (510(k) #: K072307, NeuroQ™ 3.6 (510(k) #: K130451, and Hermes Medical Solutions AB, Hermes Medical Imaging Suite v5.2, Reference K121278. To our knowledge there have been no safety problems with NeuroQ™ - PET DP K041022 which has been in the marketplace since June 2004, NeuroQ™ 3.0 510(k) #: K072307 which has been in the marketplace since March 14, 2008, NeuroQ™ 3.6 510(k) #: K130451 which has been in the marketplace since May 17, 2013, Hermes Medical Solutions AB, Hermes Medical Imaging Suite v5.2, Reference K121278 which has been in the marketplace since December 18,

7. Performance Testing Summary
Non-clinical tests:
We have compared the processing and output of the substantially equivalent devices in their literature, web site, and Pre-Market Notification Summaries for Hermes (DATSCAN™) and General Electric (DaTQUANT™). Both of these programs provide similar analysis as the DaTSCAN analysis in NeuroQ v3.8. They all enable visual evaluation and quantification of the DaTSCAN images. They provide a normal database to enable quantification relative to a population of DaTSCAN images without reduced uptake of the dopamine transporter radiotracer (DaTSCAN). All of these medical devices provide a method for automatically defining regions of interest over the left and right basal ganglia and to calculate uptake values for the administered radiopharmaceutical imaging agent (DaTSCAN) in these regions. They all provide analysis of the basal ganglia using the SPECT DaTSCAN imaging agent.
Clinical tests:
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 and NeuroQ™ 3.0, has been established in in-house testing and clinical validation studies submitted in our previous 510(k) K041022 and 510(k) #: K072307. The validation for basal ganglia analysis consisted of determining the inter-observer reproducibility of determinations of the scans being without versus with reduced dopamine transporter and the accuracy of the application. Inter-observer reproducibility was highly significant, even between trainee interpreters using the module for quantifying basal ganglia sub regions (e.g., ratios of right posterior putamen to right anterior putamen Pearson coefficient r=0.59, p=0.00002: ratios of left posterior putamen to left anterior putamen r=0.78, p
