Application of Fast Fluid-Attenuated Inversion Recover Pulse Sequence in Cerebral Diseases

Objective To study the value of fast FLAIR(fluid attenuated inversion recovery) in cerebral diseases. Materials and Methods 76 patients of cerebral diseases were performed fast FLAIR and T 2 weighted fast spin echo(FSE) sequence prospectively, and a comparative study of FSE and fast FLAIR imaging was made.Results FLAIR sequence demonstrated 172 foci of lesions, whereas FSE showed 123 foci. The former was more sensitive than the later. The extent and border of lesions were shown better on FLAIR imaging than on FSE. Moreover, the high contrast of lesion to normal and lesion to CSF (cerebrospinal fluid) were shown on FLAIR imaging. Conclusion FLAIR sequence is superior to FSE T 2WI in the detection of cerebral lesions, especially in the case while the lesions were around the cerebral surface or ventricle. FLAIR has been suggested to be a routine imaging sequence of choice in the brain due to an important value in diagnosing brain disease.
