I submitted this question years ago. Answer to this question and anyone else with an issue in SNR testing is: it was the phantom. GE coils as with all coils have SET phantoms that should be used due to the system programming. It looks for the gaps/spaces between the phantom balls, blocks, etc. At that time of question above the FE doing the testing was using USAI phantoms (which are large blocks) and GE CTL phantoms are small/mid size balls contained in an acrylic piece. After complete rebuild of 25 CTL's figured I got bench testing these things down to a science, with T1/T2 values higher than OEM. I can thank that FE, because it made me improve my reverse engineering skills, which I've applied to so much since then.
