DWEPI Ghosting with ASSET On.
Symptom
MRIQ DWEPI Ghosting with ASSET On. PURE On/Off Makes No Difference See Long Description See Attachment for the images. Ever since this 1.5T Excite HD system was upgraded from 12.0 M5A software to 12.0 M5B software (via FMI 60752), there is extreme phase ghosting on DWEPI images with ASSET turned on. The ghosting is gone with ASSET off. This problem did not exist before the upgrade. The problem is not intermittent, it happens all the time, even after rerunning the ASSET calibration. The ghosting is unchanged if just PURE is removed, and ASSET is left on, so PURE on or off makes no difference in this case. The FE can duplicate it every time with a phantom also. No error messages are seen or logged.
