What MRI Scanners Have Decay Variance Been Tested With?
Decay variance has been tested on a range of field strengths from 3T to 7 T. Current validation research includes 1.5T scanners, but these results are not yet available. So far, Decay Variance has been used with Siemens, Philips and Bruker scanners. Generally, any scanner that is able to perform a CPMG-type multi-echo sequence and output data in a standard format (such as DICOM) should be adequate.
