CaliberMRI – Model 321 DSC phantom for MRI
The CaliberMRI Dynamic Susceptibility Contrast DSC Phantom is the CaliberMRI Model 321 for technical standardization support in dynamic susceptibility contrast MRI.
Typical use
Suitable for MRI, research and QA/QC teams that need a physical reference for DSC sequence tracking, rCBV technical comparison and documented protocol stability, while validating local compatibility and use.
Key points
- The official page states use for standardizing dynamic susceptibility contrast imaging in support of rCBV imaging biomarkers and DSC sequence development.
- The public spec sheet identifies the product as Model 321 Delta/Dynamic Susceptibility Contrast DSC Phantom.
- Developed in conjunction with NIST following the RSNA/QIBA Dynamic Susceptibility Contrast MRI DSC-MRI profile, DSC-2020.01.29.
- 194 mm spherical shell, listed by the supplier as fitting most MRI scanners and head coils.
- Includes ten 30 ml vials with aqueous agarose solutions in concentrations from 0.2% to 3.0%, doped with 0.01 mM GdCl3.
- Includes chemical reference solutions: three 30 ml vials with 0.047 mM MnCl2 and three 5 ml physical reference vials with 1.0 mM GdCl3.
- The spec sheet lists a ten-element MR-readable LC thermometer for temperature compensation from 15 C to 24 C.
