MRI scan

Keira

Is it possible to have an idea of the size of a lesion off an mri scan by looking at it? If so what size do you think this might be close too? I’m just curious I’ll be going back to see the doctor soon, I remember the doctor told me my previous measurement was 13mm

No one knows what it is yet I’m just a little curious if it might of grown, also why would they not use contrast dye this time
