A Universal Standard for Quantitative MRI Diffusion Imaging

High Precision Devices' Quantitative (qMRI) Diffusion Phantom is a commercialized version of the QIBA DWI phantom specifically designed for MRI scanners mapping isotropic diffusion processes of water molecules. It consists of a plastic sphere similar in size to a human head and vials with various concentrations of the polymer polyvinylpyrrolidone (PVP) in aqueous solution. The solutions are referenced to NIST for the most accurate assessment and standardization of MRI scanners performing measurements of the apparent diffusion coefficient (ADC).

Key Features

  • Diameter: 194 mm
  • 13 vials filled with aqueous solutions of PVP from 0 to 50 % w/w
  • Measurements taken with vials in ice bath at 0°C
  • Temperature probe port for easy measurement of temperature
  • Interchangeable vial plate for accommodating vials of different sizes.
