Application of FAST-FLAIR imaging to patients with cerebral infarction

Aim: To evaluate the value of Fluid - Attenuated inversion Recovery(FLAIR) pulse sequence in MRI study for patients with cerrebral infarction. Methods: Seventy - one patients with cerebral infarction were studied with FAST - FLAIR sequence and T2 - weighted fast Spin - echo sequence prospectively, and a comparition between T2- weighted imaging and FAST - FLAIR imaging was made. Results: In our study, 210 and 150 infarcted lesions were detected with fast - FLAIR and T2WI respectively. The extent of the infarcted lesions and the border of the lesions were better demonstrated in fast FLAIR sequence. Conclusion: The infarcted lesions of the brain were demonstrated by FAST - FLAIR sequence better than T2 weighted sequence, espcially in the case while the lesions were around the cerebral surface or ventricle. FAST - FLAIR sequence is an important complementary technique for foutine sequence of patients with cerebral infarctions.
