Application of Fluid-attenuated Inversion Recovery(FLAIR) Sequence in Cerebral tumor Using Low Field Strength MR

Objective: To evaluate the value of fluid-attenuated inversion-recovery(FLAIR) sequences in cerebral tumor with low field strength MRI.Methods: 50 patients with cerebral tumor were studied with MR FSE-T2WI and FLAIR technique.The detectable abilities of lesions with FLAIR and FSE-T2WI were compared.Results: The FLAIR image showed 64 lesions(100%),but the FSE-T2WI only showed 56 lesions(87.5%).46 lesions(71.88%)were clear with FLAIR in demonstrating the intrinsic structure and border of lesions,and 27 ones(42.19%)with FSE-T2WI.Therefore,the FLAIR images were superior to FSE-T2WI in demonstrating the intrinsic structure and border of lesions(P0.01).Conclusion: In low field MR of the brain,FLAIR sequence was helpful to differentiate the tumor from edema,visualize the intrinsic structure of lesions.Therefore,FLAIR should become a conventional sequence in the diagnosis of cerebral tumor.
