1 A: Chemical shift artifact (arrows) on T1-weighted gradient echo scan in right ovarian dermoid cyst. This finding is the white on black line that occurs at the fat–water interface in the frequency encoding direction and is pathognomonic of a dermoid cyst. B: Note the dark signal in the fat contents (arrow) on this T1-weighted fat-suppressed gradient echo scan.
