MRI: T2WI: often high SI T1WI: iso SI T1WI C+: avid enhancement However, the MR signal intensity may be variable according to the degree of cellularity, myxoid change, and collagenization. Low signal intensity on T2-weighted image correlating with less cellularity and myxoid change with higher collagenization Reference) Rhim Jung hyo, Kim Ji-hoon, et al.
