I had MRI of the femur and pelvis. Can you explain abnormal findings:
"Marrow signal abnormality in the metaphysis and diaphysis of both femora without lesion. Possible red marrow conversion".
Specifics of MRI show:
MRI shows patchy low T1 and high T2 marrow signal in meta and diaphysis in both femur. At mid diaphyseal level, curvilinear bright T2 and STIR signal noted in the intramedullary cavity. No lesion noticed.
Thanks for any insight. Is there another website I could use for more information?

Hi. I have recently been experiencing an artifact on a STIR sequence (GE Signa HDxT 3.0T) using a HD CTL spine Coil. I'm am not fully understanding what could be happening here. One MRI technologist thought it was a corduroy artifact due to RF leak, but I'm not 100% sure there was RF leak, at least from the door, as it was closed completely.

My understanding with Stir is to have longer TR and shorter TE than a normal T2 sequence. Ive also wondered this question and have not found a definite answer as I guess it could vary from manufacturer to manufacturer?
Im on a Siemens Avanto 1.5T, and typically our STIR sequence ranges from:
TR = 4000 - 10,000ms (I try not to go beyond 7,000)
TE = 20 - 40ms
...obviously you can adjust values for different outcomes depending what you are trying to identify.
