FDG-PET vs. Advanced MRI: A Comparative Look
While FDG-PET remains a cornerstone for cancer detection and staging, advanced MRI techniques offer distinct advantages, particularly in probing real-time metabolic flux without ionizing radiation.
| Feature | FDG-PET | Hyperpolarized MRI (HP-MRI) | Deuterium Metabolic Imaging (DMI) |
|---|---|---|---|
| Tracer Type | Radioisotope ([18F]FDG) | Stable Isotope ([1-13C]Pyruvate, DHA) | Stable Isotope ([2H]-Glucose, [2H]-Fructose) |
| Mechanism | Glucose uptake, Hexokinase activity, Retention of FDG-6-P | Real-time enzymatic flux (e.g., pyruvate to lactate) | Production of deuterated water (HDO), downstream metabolites (lactate, glx) |
| Clinical Use | Gold standard for detection & staging | Emerging pre-clinical, early clinical trials | Emerging pre-clinical, early clinical trials |
| Sensitivity | High | High (via DNP/PHIP enhancement) | Moderate to High |
| Downstream Metabolism | Limited | Yes (kinetic modeling of metabolic products) | Yes (direct detection of deuterated products) |
| Ionizing Radiation | Yes | No | No |

Case Study: Dual-Probe HP-MRI for Redox & Glycolysis Insights
Researchers utilized hyperpolarized dehydroascorbic acid (DHA) and pyruvate to image brain metabolism in a murine model. This combined probe approach revealed increased production of lactate in white matter and increased reductive and oxidative capacity in gray matter, offering valuable biological insights and foundational methodology for clinical translation.
Key Result: Simultaneous assessment of redox and glycolytic pathways provided enhanced biological context for metabolic dysregulation in cancer.
DMI: Tracing Glucose & Fructose Metabolism with Deuterium
Deuterium Metabolic Imaging (DMI) offers a non-ionizing way to track glucose and fructose metabolism and their products, with ongoing advancements in speed and sensitivity.

Case Study: Rapid [2H7]glucose DMI for Anti-Glycolytic Efficacy
Intravenous administration of a perdeuterated glucose tracer, [2H7]glucose, generates rapid metabolic contrast through HDO production within 5 minutes. This approach provides advantages over [6,6'-2H2]glucose by allowing immediate tracking of glucose utilization kinetics, reporting effectively on anti-glycolytic therapeutic efficacy in murine flank tumor models.
Key Result: Rapid (within 5 minutes) and distinct HDO production kinetics allow for early assessment of therapeutic efficacy.
CEST MRI: Endogenous Probes for Glycolytic State
Chemical Exchange Saturation Transfer (CEST) MRI techniques are advancing to detect endogenous glycolytic metabolites and energy reserves like glycogen.
Case Study: Monitoring Glycolysis via Endogenous 31P CEST
Vassallo et al. (2025) demonstrated that ³¹P CEST can monitor glycolysis by tracking endogenous pool sizes of phosphorylated glycolytic metabolites (e.g., glucose-6-phosphate, phosphoenol pyruvate). This method involves selective saturation transfer, revealing greater glycolytic metabolite pool sizes in tumors compared to adjacent muscle tissue in vivo.
Key Result: Direct detection of tumor-specific phosphorylated glycolytic metabolite pools without exogenous tracers.
Case Study: GlycoNOE Imaging for Glycogen Storage in Tumors
Glycogen nuclear Overhauser effect (glycoNOE) imaging leverages through-space magnetic coupling between glycogen and water to achieve higher resolution and intensity. While initially published in the context of hepatology, this technique holds significant promise for exploring the role of glycogen storage and its modulation in tumors to reveal metabolic contrast.
Key Result: High-resolution, sensitive imaging of glycogen stores provides insights into tumor energy reserves.
