The core challenge in advanced oncological imaging is the manual, labor-intensive nature of image quantification. Clinicians spend hours outlining tumors and organs (segmentation) to assess disease burden. This process is not only a major workflow bottleneck but also suffers from high inter-observer variability, meaning different experts can get different results from the same scan. This inconsistency hinders the reliable use of advanced, quantitative biomarkers like Total Metabolic Tumor Volume (TMTV), which are proven to be highly valuable for prognosis and therapy planning.
The proposed solution is the deployment of AI, specifically deep learning models (like U-Nets), to perform fully automated segmentation of PET/CT images. These models are trained on large datasets of expert-annotated scans to learn how to identify and delineate tumors and healthy organs with high accuracy. This technology, especially when combined with the superior image quality from new Long-Axial Field-of-View (LAFOV) scanners, provides a consistent, reproducible, and scalable method for extracting rich quantitative data from every scan.
For a healthcare enterprise, implementing this AI-driven approach offers a multi-faceted impact. Operationally, it dramatically reduces the time and cost associated with image analysis, freeing up expert clinicians to focus on higher-value tasks. Clinically, it improves the quality and consistency of care by standardizing diagnostics and enabling data-driven therapy planning. Strategically, it positions the organization as a leader in personalized medicine, attracting talent and patients while enabling participation in cutting-edge clinical trials and research.

Case Study: Prostate Cancer Therapy Planning
The paper provides a compelling use case in planning radioligand therapy (e.g., [177Lu]Lu-PSMA) for prostate cancer, where precise quantification is essential for predicting treatment response and toxicity.
Traditionally, determining a patient's eligibility for PSMA-targeted therapy involves a visual analysis of a PET scan, which can be subjective. The research demonstrates that AI-driven methods can automatically segment all tumors in the body to calculate the total tumor volume (TMTV) and other PSMA-expression metrics. This automated, quantitative approach provides a robust biomarker that is strongly associated with therapy response. Furthermore, AI can segment healthy organs, enabling accurate dose prediction to minimize toxicity. This transforms therapy planning from a qualitative assessment to a data-driven, personalized strategy, improving patient selection and outcomes.
Building the Future: Normative Databases
A key opportunity enabled by low-dose LAFOV scanning and AI is the creation of large-scale 'normative' databases of healthy individuals. This establishes a baseline for 'normal' radiotracer uptake, revolutionizing anomaly detection.
