PDFF Phantoms

Calimetrix PDFF (Proton-Density Fat-Fraction) Phantoms are designed for testing and quality control of magnetic resonance (MR)-based fat quantification.

  • Housing-Based Phantoms: Optimal image quality for independent reference standard scans.

  • Phantom Pack: Reference standard for quality assurance embedded in every patient scan.

Clinical Relevance of PDFF Quantification

MRI-based triglyceride metrics can be useful for diagnosis, quantitative grading, and treatment monitoring of non-alcoholic fatty liver disease (NAFLD), also known as steatotic liver disease (SLD), and other diseases. However, such quantitative metrics must be both accurate and reproducible. Our Model 300, Model 600, and Phantom Pack products focus on the 0-50% PDFF range that is relevant for NAFLD. Our Model 825 product includes PDFF values that sample the complete range from 0-100% PDFF. This is relevant for the following tissues:

  • Fatty Liver Disease: 0-50% PDFF

  • Fatty Infiltration of Muscle: 0-15% PDFF

  • White Adipose Tissue (e.g. Subcutaneous Fat): 75-100% PDFF

  • Brown Adipose Tissue: 20-85% PDFF

  • Red Bone Marrow: 20-70% PDFF
