The goal of current study is to validate whether the contrast enhanced T2 FLAIR (CE-T2-FLAIR) could provide additional value for clinical diagnosis beyond the regular sequence. A retrospective analysis of 52 cases of intracranial ring-enhanced lesions validated by menstrual surgery, pathology or clinical follow-up observation from January 2019 to June 2020 was performed in current study. Our results demonstrated that the CE-T2-FLAIR "edge enhancement sign" was more closely related to inflammatory lesions, and indicated a high possibility of that disease.
