PET Image Quantification

Assess FDG PET/CT study comparability using glucose-aware quantitative standards.

This tool helps technologists and clinicians understand how blood glucose, uptake time, and dose timing may affect quantitative interpretation.

OraQuant — PET Image Quantification

OraQuant is a quantitative assessment tool designed to help imaging professionals evaluate FDG PET/CT study comparability using glucose-aware, time-aware standards.

Supports quantitative interpretation by assessing glucose level, uptake time, and dose timing timing consistency.
Designed for use before or during image review to understand potential sources of SUV variability.
Aligns with guidance from SNMMI, EANM, PERCIST, and ACR-aligned quantitative best practices.

Evaluation mode: OraQuant provides rule-based quantitative context and optional AI-assisted explanations. It does not generate clinical recommendations or replace professional judgment.

Data handling: This tool is intended for educational and workflow support. Do not enter patient identifiers or protected health information (PHI).
