I need to know what color scsr tissue would be on an mri done with no contrast! i had a double laminectomy 6 mo ago, at l 4-5 & l 5/s 1.

Contrast needed to: tell scar tissue from other tissues, unfortunately. The truthful answer to your question is "gray". Scar tissue is a relatively bland gray on all sequences of a noncontrast MR. That is why contrast is recommended in patients who've had surgery. If you have MR on CD, I can review at HealthTap Concierge, healthtap.com/saurbornmd, but I may not be able to answer your question without contrast images.
