From: Mature cystic teratoma of the ovary: a cutting edge overview on imaging features
Axial T2-weighted (a), fat-saturated T2-weighted (b), in-phase (c) and opposed-phase T1-weighted (d) MR images of a 56-year-old female with a floating ball (arrowheads) in a mature cystic teratoma. The central core of the ball contains minor fat, which is seen as decreased signal intensity in the opposed-phase image, and an outer layer with a major fat signal that decreases in the fat-saturated T2-weighted image
