MR of the brain using fluid-attenuated inversion recovery (FLAIR) pulse sequences.

摘要: PURPOSE Results from conventional T2-weighted spin-echo sequences were compared with those obtained using fluid attenuated inversion recovery (FLAIR) pulse in order to assess their relative merits detecting disease. METHODS Forty adult patients suspected disease of the brain examined (TE = 20 and TE 80), results FLAIR several types times 1800-3000 msec echo 130-240 msec. Scans assessed by two radiologists for lesion number, conspicuity, extent. RESULTS A total 48 lesions or groups recognized both sequences. In 22 instances, more seen sequences, and, remaining 26, equal numbers seen. 42 lesions, conspicuity was better five worse one cystic lesion. Lesion extent 28 cases equally well remainder. CONCLUSION By virtue long time freedom cerebrospinal artifact provide high sensitivity a wide range disease. The basic sequence is easy implement but relatively consuming.
