| 摘 要： | 目的比较液体衰减反转恢复(FLAIR)和弥散加权成像(DWI)在急性脑梗塞中的应用。方法14例急性脑梗塞患者接受FLAIR和DWIMRI检查评价病变的显示范围,边界及对比度并计算病变区。结果FLAIR序列和DWI对病变的显示范围,均优于常规T2WI,以DWI对病变显示更佳。结论FLAIR和DWI在急性脑梗塞中均有用,以DWI最好,且能对急性脑梗塞作定量评价。

| Abstract: | Objective: To Compare fluid-attenuated inversion reloverly(FLAIR)sequence and diflusion-weighted imaging (DWI)sequence in evaluation of acute cerebral infarction. Methods: 14 cases of acute cerebral infaretion were examined with FLAIR and DWI sequences on1. 5T MR scanner. The extent, boundary and contrast of the lesions on all images were evaluated. Apparent diffusion coefficient (ADC)and relatine ADC (rADC) of the lesions were calculated. Results: The extent, boundary and contrast on FLAIR and Dwimageswere superior to conventional T2WI. The visualization of the lesions on DW images was proved to be the best. Conelusion: Both FLAIR and DWI sequences are more Valuble on Visualization of acute cerebral infarction than conventional T2WI sequence. DWI was the best to show the lesions,furthermore, it can assess the infarction area quantitatively. |
