Example

Modic type
1 - edema/inflammation (T1 low, T2 high)

Result: Modic type 1: bone-marrow edema / inflammation, T1 hypointense and T2 hyperintense.

The tool opens with these values already filled in. Replace them with your own.

What the result means

Type 1
Bone-marrow edema / inflammation: T1 hypointense, T2 hyperintense.
Type 2
Fatty (yellow) marrow: T1 hyperintense, T2 iso- to hyperintense.
Type 3
Subchondral bony sclerosis: T1 hypointense, T2 hypointense.
