Malignant melanoma with pet positive femur lesion- what OT-RADS would you give

Yes

Since dwi is so bright with adc of 0.5
pet positive and incr perfusion

I left it as OT-RADS III- probably benign and can be followed up

rather than OT-RADS II- definitely benign.

Playing safe but I agree its likely just red marrow

Best!

Does the oop loss of signal suggest this is focal red marrow rather than met?

Hoping this is correct as had a similar pet ‘+ve’ case a few weeks ago and found the oop t1 dixon useful.
