Value of fat-suppression gradient-echo MR imaging in the diagnosis of ovarian cystic teratomas.
Gradient-echo MR imaging (MRI) was evaluated for the diagnosis of ovarian mature cystic teratomas (MCTs). The FLASH technique was applied to T1-weighted images with and without fat suppression in 18 surgical operated patients with 19 MCTs, and findings were compared to those of conventional spin-echo (SE) T1-weighted-SE. Seventeen out of 19 MCTs were correctly diagnosed using FLASH and SE T1-weighted MR images with and without fat saturation. This study suggests that gradient-echo MRI can replace conventional SE T1-weighted MRI for the diagnosis of ovarian MCTs.
