The NM NeuroQ 3.75 application is designed to help clinicians perform a quantitative analysis of FDG-PET brain scans. The application compares the regional brain activity in an individual scan to activity values derived from a group of asymptomatic control subjects. It analyzes the distribution of FDG-PET in individual scans, as sometimes it’s hard to detect differences between two PET scans on the same patient taken at different points in time.
