摘　　要：目的探讨低场MR T2 FLAIR序列在轻微脑外伤中的诊断价值。方法对120例轻微脑外伤患者分别进行CT、常规T2 FRFSE、T1 FLAIR序列扫描并加扫T2 FLAIR序列。结果 CT平扫发现阳性病灶143个,MR常规T2WI+T1WI像发现阳性病灶118个,加扫T2 FLAIR序列后阳性病灶为176个。结论低场MR加扫T2FLAIR序列能清楚显示病灶及其范围和大小,并可增加轻微脑外伤的病灶检出率,减少漏诊。Objective To investigate the diagnosis value of low field MR T2 FLAIR sequence in mild traumatic brain injury. Methods 120 cases with mild traumatic brain injury were detected with CT plain scan,conventional T2 FRFSE, T1 FLAIR sequence scan and T2 FLAIR sequence added. Results 143 positive lesions were found in CT plain scan, 118 positive lesions were found in conventional MR T2WI plusing T1WI imaging,and after adding T2 FLAIR se- quence,176 positive lesions were found. Conculsion Low field MR adding T2 FLAIR sequence can clearly show le- sions and its scope and size,and it can increase the lesion detection rate of mild traumatic brain injury and reduce misdia^nosis
