CaliberMRI launches new preclinical MRI phantom

Boulder, CO-based CaliberMRI is releasing a quantitative MRI (qMRI) phantom for high-field preclinical scanners. 

The Model 340 includes the following: 

• A 59-mm diameter. 

• A range of T1, T2, and apparent diffusion coefficient (ADC) calibration solutions traceable to the National Institute of Standards and Technology (NIST).

• A resolution coupon insert with hole patterns from 0.4 mm to 1.2 mm in diameter, which enables measurements of the scanner’s spatial resolution. 

• The company’s patented MR-readable liquid crystal thermometer. 

The phantom is designed to let sites compare qMRI measurements across field strengths, particularly in smaller coils and on 4.7-tesla, 7-tesla, and 9.4-tesla systems, according to the company. It complements CaliberMRI’s standard phantom line, and the company cited growing interest from researchers using qMRI on preclinical and smaller-bore scanners. 

CaliberMRI will showcase the phantom at the RSNA annual meeting in Chicago, November 29 to December 2.
